Описание (английский):

Provides quidelines for determining the labelled values of the noise emitted by individually-labelled machines, that is in the situation in which each machine has its on value of its noise emission quantity. Specifies a procedure for checking compliance of noise values of machines with the labelled values.

Overview

ISO 7574-2:1985 - Acoustics: Statistical methods for determining and verifying stated noise emission values of machinery and equipment - Part 2: Methods for stated values for individual machines provides guidance for establishing and checking the labelled noise emission value for each individual machine. It covers statistical procedures for determining a machine’s declared noise value and a method to verify that a particular machine’s noise emission does not exceed its labelled limit. The standard assumes measurement by an accredited testing laboratory with appropriate facilities and trained staff.

Key topics

Scope and purpose: Methods are specific to situations where each machine receives an individual labelled noise value (i.e., each unit has its own declared noise emission).

Statistical approach: Uses statistical methods mainly to estimate parameters relevant to verifying labelled values (the document notes particular emphasis on estimation of the factor K - see clause 5).

Compliance check: Defines a procedure for testing an individual machine to confirm its noise emission is at or below the labelled value (the labelled value is treated as a limit).

Dependencies and definitions: Relies on general definitions and principles in ISO 7574/1 and references established sound power measurement methods (ISO 3741–3746 family and ISO 3744, ISO 3745, ISO 3746, ISO 3742, ISO 3743).

Assumptions and limits: Does not address regulatory or contractual consequences if a machine fails verification; focused on the statistical verification method itself.

Applications

Manufacturer labelling: For manufacturers who provide an individually-labelled noise emission value for each machine produced.

Testing and conformity assessment: For acoustic laboratories and test houses conducting verification tests and issuing compliance reports.

Procurement and contract testing: Used by buyers and contractors to confirm delivered machines meet declared noise limits.

Quality control: Employed in production quality assurance when noise performance is tracked per unit.

Regulatory support: Assists safety and environmental compliance teams in validating noise declarations for machinery.
