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.

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.
