Five Draft Standards in Public Review

Five draft standards are now in public review and will be through April 26. The standards deal with wire rope ladders, theatrical boom & base assemblies (lighting trees), the ACN protocol, pin connectors, and flat-wall photometry. The documents are accessible on the ESTA website at http://www.esta.org/tsp/documents/public_review_docs.php. The date noted on the website of April 27 is when they will disappear and will no longer be accessible.

BSR E1.1, Entertainment Technology - Construction and Use of Wire Rope Ladders, is a revised version of ANSI E1.1-1999, Entertainment Technology - Construction and Use of Wire Rope Ladders. E1.1-1999 was offered for public review to reaffirm it last year, since it was at the 5-year anniversary at which an American National Standard must be reaffirmed, revised, or withdrawn. No one offered any public review comments, but close examination of the document by Rigging Working Group members showed that the specification for the wire rope needed to be changed. This is a substantive change, so this revised version is being offered for public review.

BSR E1.15, Entertainment Technology Recommended Practices and Guidelines for the Assembly and use of Theatrical Boom & Base Assemblies, is a draft standard for the assembly and use of ground-supported variable and fixed-height lighting fixture suspension devices. These devices normally consist of a heavy floor base, a vertical member or members, and horizontal members (arms) coming of the vertical member for the attachment of luminaires or accessories. The draft standard has been offered for public review before, but substantive changes have been made in response to comments, so it is being offered for review again.

BSR E1.17, Entertainment Technology - Multipurpose Network Control Protocol Suite, is the draft standard commonly called "ACN." The draft standard is a suite of protocols offering needed services in network management, device management, device description, and device control with reliable multi-cast transport on data networks that use the common Internet Protocols. Substantive changes have been made since the last public review, so it is being offered for public review again. There are 17 documents that describe various aspects of the suite of protocols, and they are all contained in the compressed file ACN2ndReview.zip. The file is a little less than 2 megabytes in size.

BSR E1.24, Entertainment Technology - Dimensional Requirements for Stage Pin Connectors, is a configuration standard covering the dimensional requirements and mechanical requirements related to intermateability for a series of split-pin and sleeve wiring devices known as Pin Connectors or Stage Pin Connectors that are used predominately in the theatre, television and motion picture industries in North America. It is not a safety standard.

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 document has been offered for public review before, but the resolutions to the comments have resulted in substantive changes to the document, so it is being offered for public review again.

A complete public review packet consists of the draft standard and a public review response form. Members of the public are invited to review each of the draft standards and to give an opinion on its acceptability as an American National Standard so we can know if the document reflects the consensus of informed opinion in the entertainment lighting industry. Please tell the standards committee if you think the draft is good enough to become an American National Standard as it is. If you think so, please check the "Yes" box. If you think so, but you want to offer some comments, check "Yes with comments," and offer your comments in the space provided, or on additional pages, in an email message, or in some other computer-readable file. If you don't think the draft standard is acceptable, please mark "No with reasons" and state your reasons.

If you vote "No with reasons," please be as specific as you can about what needs to be changed, where, and why. For example, a comment such as, "Ropes should be longer," would not be very helpful. How long should they be? Where in the document should the rope length specification be changed? Please cite sections or quote the parts that need to be changed; do not return a marked-up copy of the draft standard. Also, please give an argument for why this change would result in a better standard. A clear argument will help the standards committee to understand what you want and why. Our goal is to draft a document that satisfies the needs of as many people in the industry as possible, so we need to know what you would want to see changed to earn your unqualified "Yes" vote.

The response form is an Adobe Acrobat 6.0 form. You can fill it out on your computer, save it, and email it back if you have a full version of Acrobat 6.0 or above. If you have Reader, you can fill it out on your computer, print it, and then mail it or fax it. You can also print the blank form and fill it in by hand and return it. If you do either of these last two things, it would be helpful if you also sent your comments or reasons separately by email. This will save a lot of retyping in the ESTA office and will help make sure your comments or reasons are recorded correctly.

Please return your comments or reasons (if you have any) on the comment form or with it to both ESTA's Technical Standards Manager and the Secretary of the ANSI Board of Standards Review. The email addresses and other contact information are given on the public review comment form.

Please also look for protected intellectual property in the draft standard. ESTA and Accredited Standards Committee E1 do not intend to adopt any standard that requires the use of protected intellectual property, unless that property can be licensed and used by anyone without prejudice or preference for a reasonable fee. If you see any protected intellectual property in the document, please point it out in your comments.
