Three draft standards have been added to those currently available for public review on the ESTA website at www.esta.org/tsp/documents/public_review_docs.php. The three additional standards are BSR E1.23, a guidance document for planning and executing fog effects; BSR E1.25, a document specifying the basic testing conditions for any of a variety of flat-wall photometry methods; and BSR E1.27-1, a standard for portable DMX512 cables.
BSR E1.23, Entertainment Technology-Design and Execution of Theatrical Fog Effects, is modeled after the well-respected NFPA standards for indoor pyrotechnics and flame effects. Those NFPA standards (NFPA 1126 and NFPA 160) help protect workers and audience members and also help simplify working with the local authority having jurisdiction for the effects designers and technicians. E1.23, when it is finished, is expected to do the same for fog effects. The review on this document runs through December 27.
BSR E1.25, Recommended Basic Conditions for Measuring the Photometric Output of Stage and Studio Luminaires by Measuring Illumination Levels Produced on a Planar Surface, describes the basic testing conditions (e.g., the condition of the luminaire, the power supply, et cetera) for any of a number of methods of measuring a luminaire's output that involve shining the light from the luminaire on a flat wall and then measuring the levels of illumination produced. The draft standard does not describe the equipment or measurement method used to measure the illumination. The major changes since the last public review have been in the sections about lamp calibration and power supply stability. The review on this document runs through January 3.
BSR E1.27-1, Entertainment Technology-Standard for Portable Control Cables for Use with USITT DMX512/1990 and E1.11 (DMX512-A) Products, is a draft standard for a very common thing: a piece of portable DMX512 or E1.11 cable. BSR E1.27-1 would standardize the wiring of a DMX512 cable and require labeling so single-pair and dual-pair cables can be distinguished from each other. The review on this document runs through January 3.
Note that the website listings show the reviews as ending the dates one day after the dates listed above. This is because the reviews listed here end when the date listed on the website begins. That is, the start of December 28 at midnight UTC marks the end of December 27; when December 28 starts, the public review running through December 27 ends, and the links to the review materials on the website will disappear.
In addition to being asked to review the documents to see if they offer adequate advice, reviewers are asked to look for protected intellectual property in the draft standards. ESTA does not warrant that its standards contain no protected intellectual property, but it also does not intend to adopt any standard that requires the use of protected intellectual property, unless that property is necessary for technical reasons and can be licensed and used by anyone without prejudice or preference for a reasonable fee. Any protected intellectual property in the document should be pointed out in the comments.
