Standard Practice for Determining the Acoustical Performance of Exterior Windows and Doors
|Publication Date:||15 August 1991|
|ICS Code (Doors and windows):||91.060.50|
1.1 This practice establishes requirements for testing and rating acoustical performance of exterior windows and doors, regardless of their method or materials of manufacture.
1.1.1 Air leakage and operating force are integral elements of acoustical performance of exterior windows and doors; therefore this practice requires concurrent testing of air leakage and operating force in addition to acoustical tests.
1.2 This practice establishes the test methodology and specimen criteria and classification rating system for purposes of determining the acoustical performance levels of exterior windows and doors only, and not through openings between such assemblies and adjacent construction.
1.3 Excluded from the scope of this practice are roof windows, skylights, sloped glazing systems, or any interior window or door assembly.
1.4 The values stated in inch/pound units are to be regarded as standard. The values given in parentheses (SI units) are provided for information only.
1.5 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.
