Historical Standard: ASTM E1111-02 Standard Test Method for Measuring the Interzone Attenuation of Ceiling Systems
SUPERSEDED (see Active link, below)
ASTM E1111
1. Scope
1.1 This test method is intended to provide measurements of the sound reflective characteristics of ceiling systems when used in conjunction with partial-height space dividers. This arrangement is commonly used in offices and schools to achieve speech privacy between work zones in the absence of full-height partitions. This test method is applicable to any ceiling configuration, including, for example, a pattern of sound-reflective panels in an otherwise sound-absorptive ceiling. This test method, as specified, is primarily restricted to measurements with a fixed space divider height of 1.50 m (60 in.), a ceiling height of nominally 2.70 m (108 in.), a source height of 1.20 m (48 in.), and microphone positions at 1.20 m (48 in.) height.
1.2 Laboratory Accreditation A procedure for accrediting a laboratory for purposes of this test method is given in Annex A1.
1.3 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.
1.4 The values stated in acceptable metric units are to be regarded as the standard. The values given in parentheses are provided for information only.
