The Floors Working Group, part of PLASA's Technical Standards Program, has announced that it is in the process of considering reaffirming ANSI E1.26 - 2006, Entertainment Technology – Recommended testing methods and values for shock absorption of floors used in live performance venues. This document defines an acceptable shock absorption testing method for floors used by performers in live performance venues. Floors that are too stiff or too flexible can lead to performer injuries or to excessive effort in dancing and performing. It also offers a range of values that have been found to be acceptable for some floors. Examples of "live performance venues" include theatre stages, drama rehearsal studios, and dance studios. Reaffirmation would make no substantive changes to the standard.
Members of the materially affected public are invited to review the existing standard and to offer their opinion as to whether it should be reaffirmed or not. The public review response form and instructions are available here .
The standard itself is available for purchase from The ESTA Foundation. List price is $40.00 for the general public and $30.00 for PLASA members. The official ANSI review period is from 15 July through 29 August 2011, but responses will be accepted now. The review is over when the posted "Review End Date" of 30 August starts UTC.
