Sets out guidelines and principles underlying the set of basic Standards (AS 1217.2 to AS 1217.7) for measuring the airborne noise emitted by machines and equipment, and provides assistance in the selection of the appropriate basic Standard. Also provides guidelines for the preparation of noise test codes for any type of machine or equipment, with the exception of moving vehicles or other non-stationary equipment, for the determination of sound power levels of noise sources.

This standard provides guidelines comprising the following:(a) Brief explanations of the principles underlying the set of basic standards, published as AS 1217.2 toAS 1217.7, for measuring the noise emitted by machines and equipment.(b) Assistance in the selection of the appropriate basic standard.(c) General information on supplementing the basic standards with instructions concerning the installation and operating conditions for the particular type of machines or equipment; such instructions are usually incorporated in test codes.FIELD OF
