Scope

1.1 This specification describes the construction and installation of a standard reference specimen for quality control of laboratory sound transmission loss measurements using Test Method E90. Test Method E90 allows a significant latitude in the construction and operation of a test facility. It is the objective of standard measurement procedures that the property of a reference specimen being measured have the same value in all facilities.

1.2 This specification addresses the need for a reference specimen for sound transmission loss facilities where measurements are made according to Test Method E90. It describes in detail how the specimen is to be constructed and installed in a test opening.

1.3 The values stated in SI units are to be regarded as standard. The values in parentheses are provided for information only.
