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.
