(Classification)Standard Classification for Acoustical Ceiling Products
Standard Classification for Acoustical Ceiling Products
SIGNIFICANCE AND USE
This classification is used to classify and aid in the selection of acoustical ceiling products.
SCOPE
1.1 This classification covers ceiling products that provide acoustical performance and interior finish in buildings. Products used in performance spaces and other special applications may require more detailed specification than provided by this classification.
1.2 This classification classifies acoustical ceilings by type, pattern, and certain ratings for acoustical performance, light reflectance, and fire safety. It does not cover the aspects of acoustical ceilings when used as a component of a system or assembly tested for fire endurance or floor/ceiling sound transmission.
1.3 This classification does not include physical properties, such as structural hardness, friability, sag, linear expansion and contraction, and transverse strength, which may affect the handling, installation, and use of acoustical ceiling products (see Test Methods C 367).

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
