PLASA Technical Standards Program Public Reviews

Eight PLASA draft standards are in public review. The draft documents, review forms, and instructions for submitting comments may be downloaded from the Technical Standards Program website at http://tsp.plasa.org/tsp/documents/public_review_docs.php. Anyone with a material interest is invited to submit comments through the end of the day September 28, 2015. Listed in order by working group, they are:

Control Protocols Working Group -- BSR E1.31 - 20xx, Entertainment Technology -- Lightweight streaming protocol for transport of DMX512 using ACN This standard describes a mechanism to transfer DMX512-A packets over a TCP/IP network using a subset of the ACN protocol suite. It covers data format, data protocol, data addressing, and network management. It also outlines a synchronization method to help ensure that multiple sinks can process this data concurrently when supervised by the same controller. This revision includes the addition of DMX universe synchronization. The review runs through September 28, 2015; it is over when September 29 starts.

BSR E1.33 - 20xx, Entertainment Technology -- (RDMnet) -- Message Transport and Device Management of ANSI E1.20 (RDM) over IP Networks This standard describes a method of implementing ANSI E1.20 Remote Device Management messaging over an IPv4 network. The primary anticipated use of the standard would be to complement ANSI E1.31 on an IPv4 entertainment lighting control network. This project was originally described as offering extensions to E1.31, but in fact the messages work alongside E1.31 in the same network environment. The review runs through September 28, 2015; it is over when September 29 starts.

Electrical Power Working Group -- 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 gives guidance on how to properly affix these mounting devices. The review runs through September 28, 2015; it is over when September 29 starts.

Floors Working Group -- BSR E1.46 - 20xx, 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 would provide that guidance for all people at risk, including employees. The review runs through September 28, 2015; it is over when September 29 starts.

Rigging Working Group -- BSR E1.4-1 - 201x, Entertainment Technology Manual Counterweight Rigging Systems The current ANSI E1.4 - 2009 standard has been opened for revision. The intent is a suite of standards. BSR E1.4-1 applies to permanently installed, manually operated systems of stage rigging hardware for the raising, lowering, and suspension of scenery, lighting, and similar loads. The review runs through September 28, 2015; it is over when September 29 starts.

BSR E1.22-201X, Entertainment Technology -- Fire Curtain Safety Systems BSR E1.22-201x is a revision of the 2009 ANSI standard. It is being updated to better align it with the requirements stated in NFPA 80. The draft standard describes the materials, design, fabrication, installation, operation, testing, and maintenance of fire safety curtains and systems used for theatre proscenium opening protection. The review runs through September 28, 2015; it is over when September 29 starts.

BSR E1.43 - 201X, Entertainment Technology -- Performer Flying Systems This document 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 under all circumstances. The review runs through September 28, 2015; it is over when September 29 starts.

Stage Lifts Working Group -- BSR E1.42 - 201x, Entertainment Technology -- Safety Standard for Orchestra Pit Lifts Stage lifts, such as orchestra pit or theatre forestage lifts, are not the subject of any current national standard. As a result, safety requirements and inspections of them are inconsistent. E1.42 is being written to address this lack of a standard. The scope is limited to safety and to orchestra or forestage lifts that are installed as a part of the building and that are not custom-built for a single theatrical production. The review runs through September 28, 2015; it is over when September 29 starts.
