This part of ISO 7574 provides guidelines for determining the labelled values of the noise emissions of individually-labelled machinery and equipment, that is, in the situation in which each machine produced has its own individually-labelled value of its noise emission quantity. It also specifies a method for verifying compliance of the noise emission of an individual machine or item of equipment with its labelled value. This part of ISO 7574 does not deal with the consequences that ensue if the stated value is not confirmed as verified for a single machine.
