ESTA Publishes Rigging System Inspection Standard

Posted on Wednesday, May 10th, 2017

Rigging system inspections are recommended as a component of theatrical workplace safety programs, but there are currently no industry-accepted guidelines for inspection frequency, who conducts the inspection, how the inspection is conducted, and what should be included in reports. The lack of industry-accepted guidelines exists both for owner-conducted and third-party inspections.

In 2012, ESTA began working on a standard for rigging system inspections. ANSI E1.47 – 2017, Entertainment Technology — Recommended Guidelines for Entertainment Rigging System Inspections, is now approved as an American National Standard and available for free download at tsp.esta.org/freestandards, courtesy of ProSight Specialty Insurance. It offers guidance on inspecting entertainment rigging system — which are systems used to lift and support scenery, luminaires, and other equipment overhead in entertainment venues, such as theatres, video/film studios, amphitheatres, and arenas used for live performances or special events — including recommended inspector qualifications and responsibilities, scope and frequency of inspections, content of the rigging inspection report, and related information concerning the inspection process. The standard may be of use to rigging system inspectors, rigging system owners, stagehands and performers, insurance companies, and occupational health and safety authorities.

Two ESTA Standards in Public Review

Posted on Thursday, March 30th, 2017

Two ESTA Technical Standards Program draft standards have been posted for public review at http://estalink.us/pr. Descriptions and deadlines for comments are as follows:

BSR E1.14 — 2001 (R201x), Entertainment Technology — Recommendations for Inclusions in Fog Equipment Manuals, applies to the instruction manuals for fog-making equipment manufactured for use in the entertainment industry. In order to use fog safely and effectively, the user must have some general knowledge of the technology, have a clear understanding of how to operate the fog making system, and be aware of the potential hazards related to the use of fog, and particularly the system that he/she is using. This standard is designed to establish guidelines for manufacturers to provide to the user the necessary information required for the safe and responsible use of fog equipment. Last reaffirmed in 2013, the 2001 version is again being considered for reaffirmation by the Fog & Smoke Working Group. The public review ends at the end of the day on May 15, 2017.

BSR E1.31 — 201x, Entertainment Technology — Lightweight Streaming Protocol for Transport of DMX512 using ACN., provides a very simple protocol that offers functionality comparable to proprietary DMX512 over Ethernet protocols while being compatible with the E1.17 suite of protocols. The standard is being revised, limited to the addition of IPv6 compatibility and the correction of errors. Input on additional features is not being sought at this time. A future revision of the standard is planned to incorporate any changes outside of this scope. That future revision will be developed following the IPv6 update. To aid reviewers in discerning which sections of the draft standard include changes, a copy of the draft showing tracked changes is included in the public review package. The public review ends at the end of the day on May 8, 2017.

The review documentation — including the draft standards, review forms, review explanations, and review instructions — is available to download from http://estalink.us/pr. Email review forms to standards@esta.org before the date listed on the public review documents page.

Three ESTA Standards in Public Review

Posted on Thursday, May 5th, 2016

00B92B28D0Three draft standards have been added to the ESTA public review page at the URL below. People materially affected by the standards are invited to review them and to offer comments, if they chose, before the reviews end on June 27. The three draft standards are:

BSR E1.40, Recommendations for the Planning of Theatrical Dust Effects — ANSI E1.40-2011 is being revised to warn against deflagration — deflagration being the technical term for the wave of flame that burned hundreds of people at a water park in Taiwan last year. Other changes include a regrouping of types of dusts and changing MSDS references to SDS references.

BSR E1.41, Recommendations for the Measurement of Entertainment Luminaires Utilizing Solid State Light Sources — ANSI E1.41-2012 is being revised to specify that the Fidelity Index (Rf) rating, as defined in IES TM-30-15, be used for reporting the production of white light of a reported CCT. The existing ANSI standard requires reporting the CQS score, but CQS has no hold in the lighting market. CRI is a flawed metric, not suitable for narrow-band emitters.

BSR E1.55, Standard for Theatrical Makeup Mirror Lighting — ANSI E1.55-2015 is being revised to add the Fidelity Index (Rf) rating per IES TM-30-15, for the same reasons that Rf is being added to E1.41.

Three Additional ESTA Technical Standards in Public Review

Posted on Thursday, April 7th, 2016

estaThree additional ESTA Technical Standards Program documents make eight in public review at http://tsp.esta.org/tsp/documents/public_review_docs.php. Comments on these additional documents are due no later than May 23, 2016. Anyone who would be materially affected by the publication of these documents as American National Standards is invited to submit comments. The three additional documents are:

BSR E1.28 — 2011 (R201x), Guidance on planning followspot positions in places of public assembly (a reaffirmation) — From the followspot position working group, E1.28 offers guidance on the planning of permanent followspot positions, including recommendations on the locations of the followspot positions within the venue, the power likely to be needed, the waste heat generated, the amount of space likely to be needed, and the fall protection and egress issues to be considered for the followspot operator’s safety. The existing standard is being considered for reaffirmation.

BSR E1.42 — 201x, Entertainment Technology — Design, Installation, and Use of Orchestra Pit Lifts (a new project) — From the stage lifts working group, BSR E1.42 intends to cover the design, construction, operation, inspection, testing, maintenance, alteration, and repair of permanently installed orchestra pit lifts and their associated parts, rooms, spaces, enclosures, and hoistways, where located in a theatre or a similar place of public entertainment.

BSR E1.56 — 201x, Entertainment Technology — Rigging Support Points (a new project) — From the rigging working group, BSR E1.56 applies to stationary rigging points that are intended to be permanent and provides minimum requirements for the design, fabrication, installation, inspection, and documentation of these rigging points for their use to support rigging loads.

Four ESTA Standards Approved and Published

Posted on Monday, March 14th, 2016

00B92B28D0Last month, the American National Standards Institute’s Board of Standards Review approved four ESTA standards: two brand-new, safety-related documents and two control protocol documents that were reaffirmed. These, and all of ESTA’s published standards, are available for free download to everyone, courtesy of ProSight Specialty Insurance, at tsp.esta.org/freestandards, or they may be purchased from ANSI or IHS.

ANSI E1.46 – 2016, Standard for the Prevention of Falls from Theatrical Stages and Raised Performance Platforms — The users of theatrical stages and raised platforms can suffer debilitating injuries from falls into orchestra pits, open stage lifts, and similar openings in stage floors. Health and safety regulations require action to prevent these falls by employees, but offer little guidance that is suitable for theatrical environments. This document provides that guidance to protect all people at risk.

ANSI E1.43 – 2016, Entertainment Technology-Performer Flying Systems — This standard establishes a minimum level of performance parameters for the design, manufacture, use, and maintenance of performer flying systems used in the production of entertainment events. The purpose of this guidance is to achieve the adequate strength, reliability, and safety of these systems to ensure safety of the performer, other production personnel, and audiences under all circumstances associated with performer flying.

ANSI E1.30-1 – 2010 (R2016), EPI 23, Device Identification Subdevice — This EPI (EPI stands for E1.17 Profiles for Interoperability) specifies a collection of properties which may be exposed by a DMP device to provide detailed information on the manufacturer, model, serial number, hardware and software revisions, and other administrative details of the device. These properties are described in a standard format as a templated DDL (sub)device.

ANSI E1.3 – 2001 (R2016), Entertainment Technology — Lighting Control Systems — 0 to 10 V Analog Control Specification ANSI E1.3 describes a method of controlling equipment by means of an analog control voltage in the nominal range from zero to 10 volts positive, with the controller sourcing the signal current.

According to ANSI Essential Requirements: Due process requirements for American National Standards, ESTA’s approved American National Standards must undergo periodic maintenance. This means that all ANS must be reviewed every five years from the date of approval, and either revised to be current, withdrawn as an ANS, or reaffirmed. Reaffirmation means that the document needs no substantive changes, and is designated with an R and the year of reaffirmation in parenthesis following the standard’s designation and original year of approval.

The ESTA Technical Standards Program is an ANSI-accredited standards development organization, created and administered by the Entertainment Services and Technology Association (ESTA) to serve its members and the entertainment technology and live event industries. The TSP publishes standards that solve problems faced by users, designers, manufacturers, and dealers of entertainment technology. Membership in ESTA is not a requirement for TSP participation, but there is a $100 annual fee for all individual participants, regardless of the number of working groups to which you apply.

There are eight working groups: Control Protocols, Electrical Power, Floors, Fog & Smoke, Followspot Position, Photometrics, Rigging, and Stage Lifts. People with a material interest in the work of any of these groups may join by submitting a working group application to standards@esta.org, one for each working group of interest.

New Standard in review: Prevention of falls on mobile stages

Posted on Wednesday, December 16th, 2015

PLASA_Standards_Logo_tag_web

 

BSR E1.57 – 201x, Recommendations to prevent falls on or off movable parade floats, movable stages, and similar moving platforms.

This standard offers recommendations to prevent falls by anyone (e.g., performers, technicians, politicians) on parade floats, movable stages, and similar moving platforms. Fall protection is needed, but this protection needs to be provided in a way that preserves the artistic intent of the moving float or platform. This document is being written to provide guidance on how to accomplish this.

 Comments are due by US COB on 2nd February, 2016.

CIE looks to update Colour Rendering Index (CRI)

Posted on Friday, November 27th, 2015

00439AA0B2The Commission Internationale de l’Eclairage (CIE) have published a position statement on their intentions to develop a new and improved colour fidelity metric that would update the CRI (Colour Rendering Index).

The CIE have also accepted that the CRI has several significant sources of colorimetric inaccuracies and accept that it should be updated with the latest well-accepted formulae and an improved set of test samples. CIE’s own Technical Committee (TC1-90) is in the process of developing a new improved colour fidelity metric that can update the CRI. The CIE also recognises that the colour fidelity metrics including the CRI do not assess other important aspects of the colour qualities of light sources, in particular, those related to colour preference.

CIE TC 1-91 is developing a Technical Report on this subject, which will be the groundwork for developing colour preference metric(s). And again the CIE’s own TC1-91 is preparing a report on this subject, which according to the CIE’s website, will be the groundwork for developing colour preference metric(s).

Importantly, the CIE supports the study of the recently published IES Technical Memorandum TM-30, to which some CIE TC 1-90 members have contributed. This work was recently proposed for consideration in TC 1-90, which voted to make its Rf metric the basis for the TC’s first working draft.

To read the full draft of the CIE Position click here.

In relation to the above, the Society of Light and Lighting has published an open letter in support of TM-30

Seven PLASA Standards in Public Review

Posted on Tuesday, November 24th, 2015

PLASA_Standards_LogoSeven PLASA North America standards are currently up for review.

New Standards:

BSR E1.53 – 20xx, Overhead Mounting of Luminaires, Lighting Accessories, and Other Portable Devices: Specification and Practice. The standard covers specifications for the primary and secondary mounting devices for portable stage and studio luminaires and accessories. It also covers these mounting devices for special effects equipment (e.g. fog machines and bubble machines) that are often mounted along with lighting equipment on trusses and rigging system battens. The standard would give guidance on how to properly affix these mounting devices. Comments are due by US COB on January 4, 2016.

BSR E1.51, The Selection, Installation, and Use of Single-Conductor Portable Power Feeder Cable Systems for Use at 600 Volts Nominal or Less for the Distribution of Electrical Energy in the Television, Film, Live Performance, and Event Industries in Canada. E1.51 is intended to offer guidance in accordance with existing applicable standards and regulations in Canada on how to select, install, use, and maintain single-conductor portable feeder cables used to supply power for television, film, live performance, and special events in Canada. Comments are due by US COB on January 4, 2016.

BSR E1.37-5 – 201x, General Purpose Messages for ANSI E1.20, RDM. This document provides additional Get/Set parameter messages (PIDs) for use with the ANSI E1.20 Remote Device Management protocol. Comments are due by US COB on January 5, 2016.

Standards to be reaffirmed:

ANSI E1.3 – 2001 (R201x), Entertainment Technology – Lighting Control Systems – 0 to 10V Analog Control Specification. The standard describes a method of controlling current-sink devices and equipment by means of an analog control voltage in the nominal range from zero to 10 volts positive, with the control signal current sourced from the controller. It is primarily intended for theatrical lighting controllers and controlled devices (e.g., dimmers), but any device could use this control method. The working group proposes to reaffirm the existing standard, which was previously reaffirmed in 2011. Comments are due by US COB on December 28, 2015.

ANSI E1.30-1 – 2010 (R201x), EPI 23. Device Identification Subdevice. This document is part of BSR E1.30, application level equipment interoperability for control of commonly encountered entertainment technology devices using ANSI E1.17. It specifies a templated device for device identification as typically used for remote hardware and software devices. The working group is proposing to reaffirm the 2010 version. Comments are due by US COB on December 28, 2015.

ANSI E1.27-1 – 2006 (R201x), Entertainment Technology-Standard for Portable Control Cables for Use with ANSI E1.11 (DMX512-A) and USITT DMX512/1990 Products. This standard describes the types of portable cable for the transmission of digital data among products which comply with ANSI E1.11, Entertainment Technology – USITT DMX512-A. It covers recommended cable types, connectors, and their internal wiring. The working group is proposing to reaffirm the 2006 version. Comments are due by US COB on January 4, 2016.

Standard to be Withdrawn:

ANSI E1.30-7 – 2009 (W201x), EPI 29, Allocation of Internet Protocol Version 4 Addresses to ACN Hosts. E1.30-7, EPI 29, is a recipe that changes some of the rules for ACN (ANSI E1.17) so that devices with IP addresses not set by DHCP can be used on a network. The standard is being proposed for withdrawal on the grounds that much of the document was based around a protocol not adopted by the market, and that implementation for IP addressing is better dealt with by designers, not through the standardization of any particular method. Comments are due by US COB on December 28, 2015.

ANSI approves two PLASA standards and the withdrawal of a third

Posted on Wednesday, October 21st, 2015

On September 25, ANSI’s Board of Standards Review approved the reaffirmation of the 2010 edition of ANSI E1.30-4, EPI 26, Device Description Language (DDL) Extensions for DMX512 and E1.31 Devices, and the revised version of ANSI E1.37-2, Entertainment Technology – Additional Message Sets for ANSI E1.20 (RDM) – Part 2, IPv4 & DNS Configuration Messages.

ANSI E1.30-4 does what the title says: it defines protocol-specific extensions to the device description language for describing DMX512 devices.

ANSI E1.37-2 is another part of the multi-part, open-ended E1.37 standard. It provides get/set parameter messages for configuring network interfaces, routing information, and DNS settings on devices with IPv4 addresses.

Both standards are now published. They may be downloaded at no charge from http://tsp.plasa.org/freestandards; the free download is sponsored by Prosight Specialty Insurance.

On October 8, the ANSI Board of Standards Review approved PLASA North America’s withdrawal of ANSI E1.45 – 2013, Unidirectional Transport of IEEE 802 data frames over ANSI E1.11 (DMX512-A). ANSI E1.45 has been withdrawn because it does not comply with PLASA’s patent policy, which states that we do not intend to publish any standard that contains protected intellectual property unless that property can be licensed by anyone for a reasonable fee on a non-discriminatory basis. There are patents issued in Korea and in the United States that cover key parts of the standard. The licensing terms offered by the patent-holder do not meet our requirements, so the standard has been withdrawn.

Weather vs. Lighting Designer

Posted on Monday, March 30th, 2015

Written by: John Featherstone

Even if Oscar Wilde did once say “Conversation about the weather is the last refuge of the unimaginative,” we all still love to talk about the weather. And, sooner or later, we will all have to do a show outside, or at the very least in a tent.

If we are honest, we are a business of “control freaks.” We love to set our own schedules, create our own environments and make our own rules. Yet the weather won’t cooperate with our schedules, seems to conspire against our creativity, and defies our rules. Whatever the reason, there is little debate that the weather is changing — storms seem to be fiercer, winds stronger, rains harder, winters colder and summers hotter. We have all seen the results of the weather catching us off guard, some of us first hand. From festival roofs collapsing to tour bus accidents, all too often lives are lost or people seriously hurt – band, crew and audience alike. So how can we learn to work with the weather, and still stay sane and most importantly safe? I’d like to use two projects as examples of how planning helps work in the face of the elements and coming out if not ahead, certainly unscathed.

Two PLASA Standards Published: A Revision and a Reaffirmation

Posted on Friday, February 27th, 2015

NSI E1.19 – 2015, Recommended Practice for the Use of Class A Ground-Fault Circuit Interrupters (GFCIs) Intended for Personnel Protection in the Entertainment Industry and ANSI E1.23 – 2010 (R2015), Entertainment Technology – Design and Execution of Theatrical Fog Effects, were approved by the ANSI Board of Standards Review on February 10th and 13th respectively. They are now published and are available for free at http://tsp.plasa.org/freestandards. The free download is made possible by the sponsorship of ProSight Specialty Insurance. They also may be purchased from ANSI’s eStandards Store (http://webstore.ansi.org/) for $15.00 each.

ANSI E1.19 is intended to offer guidance in accordance with existing applicable standards on how to select, install, use, and maintain ground-fault protection devices in the entertainment industry to protect persons from shock and persons and property from fire. This is a revision of the 2009 version that incorporates new information about avoiding nuisance tripping and offers new recommendations for ground-fault protection on higher ampacity circuits.

ANSI E1.23 offers guidance on planning and carrying out fog effects so that recognized exposure levels are not exceeded, fire and egress hazards are not created, false alarms don’t summon the fire brigade, and fog effects are executed as they are designed, performance after performance. This is a reaffirmation of the 2010 version. There are no substantive changes.

Four New Technical Standards Program Projects Announced

Posted on Tuesday, August 12th, 2014

The PLASA Technical Standards Program announces four new projects.

BSR E1.37-4 File Transfer Control to Provide Firmware Upload Capabilities — The proposal sets out the minimum requirements for controllers and responders to allow a method of firmware uploads using RDM. It defines the transfer process, command implementation, and relationship to the existing ANSI E1.20 RDM standard, and specifically provides a transfer mechanism that can be applied to memory limited responders with transmit and receive buffers as small as 64 bytes, while allowing scalable improvements (reduction in transfer times) for responders.

BSR E1.54 PLASA Standard for Color Communication in Entertainment Lighting — The goal of this draft standard is to specify a standardized color space by defining an RGB triangle and white point. Using these, manufacturers of luminaires and lighting controllers will have a common reference toward achieving consistent color. The standard will facilitate the communications between lighting controllers and color-changing luminaires by using this standardized way of specifying color. The method proposed is generic and is neither manufacturer-specific nor color technology-specific.

BSR E1.55 Standard for Theatrical Makeup Mirror Lighting — The standard would offer recommendations and requirements for makeup mirror lighting in performer dressing rooms and similar locations. It would define a range of acceptable lamp CCTs and color-rendering ratings, and would also specify illumination levels and lighting angles for illuminating the performer’s face.

BSR E1.56. Rigging Support Points Design, Fabrication, Installation, and Testing — This standard is to provide guidance for the design, fabrication, installation, and testing of permanent and temporary rigging points and rigging lugs and their connection to existing building and venue structures.

PLASA invites any interested parties to become involved with these projects, either by joining a working group or participating in future public reviews of draft standards. Working group applications may be downloaded from http://tsp.plasa.org/tsp/working_groups/index.html and public review documents are posted to http://plasa.me/4xvjf.

Three PLASA Standards Posted for Public Review

Posted on Thursday, April 10th, 2014

Three draft standards have been posted for public review on the PLASA Technical Standards Program website. The reviews run through June 2, 2014; the reviews are over and the links to the documents disappear when June 3 starts.

The three draft standards available for review are:

BSR E1.42 – 201x, Entertainment Technology — Safety Standard for Orchestra Pit Lifts. Stage lifts, such as orchestra pit or theatre forestage lifts, are not the subject of any current national standard in the USA. As result, safety requirements and inspections of them are inconsistent. E1.42 is being written to address this lack of a standard. The scope is limited to safety and to orchestra or forestage lifts that are installed as a part of the building and that are not custom-built for a single theatrical production.

BSR E1.43 – 201x, Entertainment Technology — Live Performer Flying Systems. E1.43 specifies a minimum level of performance parameters for the design, manufacture, use, and maintenance of performer flying systems used in the production of entertainment events. Performer flying systems within the scope include systems supporting people that give the impression of weightlessness, floating, or flying, and for acrobatic and circus performance acts. All locations of the flight path, including over the stage and audience, are within the scope.

BSR E1.51 – 201x, The Selection, Installation, and Use of Single-Conductor Portable Power Feeder Cable Systems for Use at 600 Volts Nominal or Less for the Distribution of Electrical Energy in the Television, Film, Live Performance, and Event Industries in Canada. E1.51 is intended to offer guidance in accordance with existing applicable standards and regulations in Canada on how to select, install, use, and maintain single-conductor portable feeder cables used to supply power for television, film, live performance, and special events in Canada.

Seven PLASA Standards for reaffirmation up for Public Review

Posted on Tuesday, January 7th, 2014

Seven PLASA standards up for reaffirmation are posted for public review on the PLASA TSP website . No changes are planned at this time for the requirements in the standards. Any changes would be limited to changing “ESTA” to “PLASA,” updating the PLASA office address and copyright date, and so on. However, this public review period is a time when the public is invited to tell PLASA if they think changes are needed.

All the documents are available for review now, and will be through 3 February 2014. On February 4 they will be gone. In alpha-numeric order the standards are:

ANSI E1.5 – 2009, Theatrical Fog Made with Aqueous Solutions of Di- and Trihydric Alcohols

ANSI E1.5 describes the composition of theatrical fogs or artificial mists that are not likely to be harmful to healthy performers, technicians, or audience members of normal working age. It is limited to those fogs and mists made from a solution of water and one or more dihydric or trihydric alcohols, and is intended to be applied in theatres, arenas, and other places of entertainment or public assembly.

ANSI E1.27-2 – 2009, Recommended Practice for Permanently Installed Control Cables for Use with ANSI E1.11 (DMX512-A) and USITT DMX512/1990 Products

ANSI E1.27-2 is a recommended practice for permanent data cabling installations for interconnecting lighting equipment that comply with ANSI E1.11 (DMX512-A) or with USITT DMX512/1990. The recommendations include definitions of acceptable cable and connector types and the ways in which they may be used.

ANSI E1.29 – 2009, Product Safety Standard for Theatrical Fog Generators that Create Aerosols of Water, Aqueous Solutions of Glycol or Glycerin, or Aerosols of Highly Refined Alkane Mineral Oil

ANSI E1.29 – 2009 is intended to help guide product safety testing laboratories in evaluating fog-making equipment for design or construction defects that might create unacceptable hazards. It is based on ANSI/UL 998 – 2006, Humidifiers, with modifications. Products covered are theatrical fog generators intended for use in professional theatrical entertainment, film and video production, theme parks, and fire safety training.

ANSI E1.30-3 – 2009, EPI 25, Time Reference in ACN Systems Using SNTP and NTP

ANSI E1.30-3 is another recipe in the E1.30 cookbook for ACN. It offers ways of providing a time reference so that events can be synchronized.

ANSI E1.30-7 – 2009, EPI 29, Allocation of Internet Protocol Version 4 Addresses to ACN Hosts

ANSI E1.30-7 is a recipe that changes some of the rules for ACN so that devices with IP addresses not set by DHCP (fixed IP addresses) can be used on a network. Device Host Configuration Protocol (DHCP) is a very convenient way to assign IP addresses on a network, but there are cases when IP addresses have to be assigned a different way, perhaps manually. This EPI suggests how.

ANSI E1.30-10 – 2009, EPI 32, Identification of Draft Device Description Language Modules

ANSI E1.30-10 is a recommended way of identifying a Device Description Language Module for ACN as a trial version, one under development, not for release yet. ANSI E1.30-10 is part of an open series of E1.30 documents that suggests ways of doing common tasks with ANSI E1.17, Architecture for Control Networks. It is being considered for reaffirmation.

ANSI E1.34 – 2009, Entertainment Technology – Measuring and Specifying the Slipperiness of Floors Used in Live Performance Venues

ANSI E1.34 describes a simple means of measuring and specifying the slipperiness of floor surfaces used by performers in live entertainment venues. The standard is not for normal walking and working surfaces, but only for those floor surfaces used by actors, dancers, and other similar artists when performing before an audience.

Proposal for new extensions to DMX512

Posted on Monday, June 3rd, 2013

The PLASA Technical Standards Council has approved a new project within the Control Protocols Working Group: BSR E1.49, DMX512 Extensions for Architectural Lighting.

The project is in response to the increased use of ANSI E1.11 in architectural applications, sometimes with proprietary Alternate START Code messages to make it more suitable for these applications. Of particular interest is providing direct control of architectural luminaires rather than simply controlling dimmers or switches that power them.

At this time the project is expected to build on ANSI E1.11’s physical layer, but initial investigations will consider if EIA-485-A is indeed the best networking technology for direct luminaire control.

People and companies having a material interest in this project are invited to participate, either by joining the Control Protocols Working Group or by responding during future public reviews of the draft document. Membership in PLASA is not a requirement for working group membership, but voting members are required to attend meetings and to vote on letter ballots.

More information about joining working groups and a link to the required working group application form are available at tsp.plasa.org/tsp/working_groups/index.htm

And just a reminder in case you missed the recent announcement that all PLASA Technical Standards are now available free to download, courtesy of ProSight Specialty Insurance at plasa.me/prosightstgecrft. (If only someone would do the same thing to improve safety in Australia by providing access to  Australian Standards like Test & Tag.)

Three PLASA Standards in Public Review

Posted on Wednesday, February 6th, 2013

Three PLASA standards are now in public review. The public review materials for the standards are available at the URL below. The last day to comment for each of them is April 1. The reviews have ended when April 2 starts.

BSR E1.44 – 201x, Common Show File Exchange Format for Entertainment Industry Automation Control Systems – Stage Machinery, defines a common show file format for the exchange of automation control data between control systems by different manufacturers of stage machinery.

BSR E1.45 – 201x, Unidirectional Transport of IEEE 802 Data Frames Over ANSI E1.11 (DMX512-A), defines a minimal method to transport IEEE 802 data frames unidirectionally over ANSI E1.11 physical links using an Alternate START Code. The primary motivation is to allow communication of 802 data to luminaires over an ANSI E1.11 DMX512-A datalink for data transmission from those luminaires using Visible Light Communication, IEEE 802.15.7. However, this standard may be used to transport any 802 data for any purpose.

BSR E1.48 – 201x, A Recommended Luminous Efficiency Function for Stage and Studio Luminaire Photometry, specifies an energy-based luminous efficiency function V(lambda) based on recent research for use when measuring the lumen output for any stage or studio luminaire in which it is known or believed that 20% or more of the output power is at wavelengths shorter than 500nm. Most light meters in use today use the 89-year-old CIE 1924 V(lambda) function. It’s wrong, so the meters are wrong. This standard is intended to encourage the use of a far more accurate V(lambda) function in the entertainment industry.
