The Entertainment Services and Technology Association's technology standards program has released two more draft American national standards for public review: E1.1, Entertainment Technology--Construction and Use of Wire Rope Ladders; and E1.3, Entertainment Technology--Lighting Control Systems--0-10V Analog Control Protocol. E1.1 describes the ladders often used on rock-and-roll shows to allow access to trusses, while E1.3 specifies technical details for 0-10V analog lighting control protocol.

For review copies, contact the technical standards manager at the ESTA office by mail, fax, or e-mail. The documents will also be available on the ESTA website at www.esta.org. Comments should be returned to both the ESTA technical standards manager and the ANSI board of standards review.
