AS 5331:2019 PDF
The objective of this Standard is to provide guidance for the use of a set of 12 basic International Standards (see Tables 1, 2 and 3) describing various methods for determining sound power levels from all types of machinery, equipment and products.
This Standard provides guidance on the selection of one or more of these Standards, appropriate to any particular type of sound source, measurement environment and desired accuracy. The guidance given applies to airborne sound. It is for use in the preparation of noise test codes (refer to ISO 12001) and also in noise emission testing where no specific noise test code exists. Such standardized noise test codes can recommend the application of particular basic International Standard(s) and give detailed requirements on mounting and operating conditions for a particular family to which the machine under test belongs, in accordance with general principles given in the basic standards.
This Standard is not intended to replace any of the details of, or add any additional requirements to, the individual test methods in the basic International Standards referenced.
This Standard is identical with, and has been reproduced from, ISO 3740:2019, Acoustics — Determination of sound power levels of noise sources — Guidelines for the use of basic standards.
