ASTM WK77043

Revision of C423-17 Standard Test Method for Sound Absorption and Sound Absorption Coefficients by the Reverberation Room Method


None Provided


Adjunct material The referenced document refers to the fabrication and construction of a round robin reference specimen dating back to the early 80s. The material is not available and was a special manufacturing run at the time. Per the current staff manager there have been no requests for this material. The material is very dated and could confuse the newest reader of the standard. At a recent sub event the committee chair proposed removal from the standard and received no opposition.
