Control Protocols, Luminaire Inspection, and Floors Testing Draft Standards Are Offered for Review
The public is invited to review three newly revised draft standards in control protocols, luminaire inspection, and floors testing. The three draft standards are posted for free download on the ESTA website at http://www.esta.org/tsp/documents/public_review_docs.php. They will be available there for review from now through September 22; the documents will be removed when the ending date shown on the website, September 23, is reached. The three draft standards are:
BSR E1.31 - 200x, Entertainment Technology - Lightweight streaming protocol for transport of DMX512 using ACN, describes a way of transporting DMX512-type data over Ethernet using ACN's Session Data Transport mechanism. DMX512-type streaming data can be intermixed with random access data and high speed feedback in a flexible and scalable way.
BSR E1.32 - 200x, Recommended Practice for the Inspection of Entertainment Industry Luminaires, is intended to help people evaluate luminaires to see whether they are reasonably safe or are in need of repair or maintenance. The project was started in response to discussions about what causes "false tripping" with GFCIs are used in entertainment venues. Sometimes the tripping isn't false at all, but is the proper response to poorly maintained lighting equipment with excessive leakage current. Proper maintenance is essential for equipment safety, and proper luminaire maintenance starts with a regular inspection procedure and schedule. BSR E1.32 is designed to help people establish a regular procedure for inspecting the equipment for which they are responsible. The information in the draft document is intended to supplement and not to replace the information contained in a manufacturer's maintenance instructions.
BSR E1.34 - 200x, Entertainment Technology - Measuring and Specifying the Slipperiness of Floors Used in Live Performance Venues, describes a way of measuring and specifying the slipperiness of floor surfaces used by performers in live entertainment venues. Right now, discussions of whether a performance floor is too slippery or not slippery enough are entirely subjective. It is difficult for portable flooring manufacturers to tell prospective customers how slippery or not a floor surface might be. This draft standard describes a simple way of testing a floor to arrive at a specification for the floor when tested with standardized stainless steel test feet and when tested with show-specific performers' footwear.
In addition to being asked to review the documents to see if they offer adequate advice, reviewers are asked to notify ESTA of any 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 by anyone without prejudice or preference for a reasonable fee. Any protected intellectual property should be noted on the public review response form.
