This part of ISO 7574 is derived from ISO 7574/4. It provides guidelines for determining the labelled value, Lc, by the labeller and specifies a simple method for verifying compliance of the noise emissions of a batch (lot) of machinery or equipment with its labelled value, Lc. This method may be used when a specific noise labelling code (in accordance with clause 6 of ISO 7574/4) specifying the reference Standard deviation, Sample size and sampling procedure for the family of machines does not yet exist. If a specific noise labelling code exists, it shall be used, in which case reference to this part of ISO 7574 shall not be made.

This patt of ISO 7574 should preferably be used only by agreement, e.g. as reached in the Standards relating to the relevant machinery industry or in a contract.

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 of machines.
