1.1 This guide is intended to assist acoustical consultants, architects, specifiers, and others in understanding ASTM standards in environmental acoustics, so that building specifications and other documents can accurately refer to relevant standards. The full standards are found in alphanumeric order in Volume 04.06 of the Annual Book of ASTM Standards .

1.2 The scope of Committee E-33 is: "The development of standards on the characteristics and performance of materials, products, systems, and services relating to the acoustical environment and the promotion of related knowledge." Only standards under the jurisdiction of Committee E-33 are included in this guide. Additional standards related to environmental acoustics may be found under the jurisdiction of other ASTM committees.

1.3 None of the discussions herein is sufficiently detailed to substitute for reading the full standard. Only a careful reading of a standard will provide a complete understanding of its function. This guide is specifically NOT to be used as a direct reference in building specifications. Only the original standard gives sufficient information to serve as a specification reference.
