SIS SS-ISO 7574/4:1986 Acoustics - Statistical methods for determining and veryfying stated noise emission values of machinery and equipment - Part 4: Methods for stated values for batches of machines
This part of ISO 7574 provides guidelines for determining the iabelled value, Lc, by the labeller and specifies statistical sampling procedures for verifying compliance of the noise emissions of a batch (lot) of machinery and equipment with its Iabelled value.
This part of ISO 7574 is intended to assist those parties respon-sible for drawing up specific labelling codes for specific families
of machines. It is also intended to be of use to labellers who want their batches of machines to conform with verification procedures that are in accordance with the specifications given in the specific labelling codes based on clause 7.
This part of ISO 7574 does not deal with the consequences that ensue if the stated value is not confirmed as verified for a batch (lot) of machines.
