Scope

This International Standard --gives information on the declaration of noise emission values, -- describes acoustical and product information to be presented in technical documents for the pur- poses of noise emission declaration, and -- specifies a method for verifying the noise emission declaration It is applicable to machinery and equipment. The values to be used for the purposes of noise emission declaration are either declared single- number noise emission values, Ld, or declared dual- number noise emission values, L and K.L is a noise emission value determined directly from measure ments and K is the uncertainty associated with those measurements. Ld is the sum of L and K and rep- resents an upper limit which values from repeated measurements are unlikely to exceed at a given con- fidence level; Lc corresponds to the stated or labelled value Lc, defined in ISO 7574-1. The two forms of noise declaration are alternative means of representing any or all of the A-weighted sound sower level, LwA, the A-weighted emission sound pressure level at specified positions, Lpa, and the C-weighted peak emission sound pressure level at specified positions, LpC peak. The choice as to which of the two forms is used in a particular case depends upon the requirements to be fulfilled. This selection is mace, and guidance on the values of K is given, in the appropriate noise test code Guidelines for determining declared noise emission values are given in annex A
