This test method describes the laboratory measurement of the sound transmission loss for door panels and door systems. It also includes the measurement of the force required to close and latch, as well as to unlatch the door under test. An appendix presents methods to determine the respective contribution of the door components and seals to the sound transmission loss of a door system.

Formerly under the jurisdiction of Committee E33 on Building and Environmental Acoustics, this test method was withdrawn in January 2009 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

This test method is used for three purposes: the laboratory measurement of (1) the sound transmission loss of fully operable doors equipped with a particular combination of hardware and seals, (2) the sound transmission loss of a laboratory sealed door panel and (3) the force or torque required to operate the door system.

This test method relies upon Test Method E 90 for acoustical testing, and all requirements in that standard, including Annex A2 (Laboratory Accreditation). Also see 6.1 for additional references and requirements.

This test method is not intended for field tests. Field tests of sound transmission should be performed in accordance with Test Method E 336.

This test method evaluates the overall sound transmission loss of an operable door system which may include various seals and hardware components. An additional (nonmandatory) test procedure for assessing individual door components is given in Appendix X1.

1.1 This test method describes the laboratory measurement of the sound transmission loss for door panels and door systems. It also includes the measurement of the force required to close and latch, as well as to unlatch the door under test. An appendix presents methods to determine the respective contribution of the door components and seals to the sound transmission loss of a door system.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
