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

EN 27574-2:1988 (identical to ISO 7574-2:1985) covers statistical methods for determining and verifying stated noise emission values of individual machines. It provides guidelines for establishing a machine’s labelled noise value (the declared sound emission or upper noise limit for that specific machine) and specifies a procedure to check whether the measured noise emission of an individual machine complies with that labelled value. The standard assumes measurements are carried out by a competent testing laboratory using appropriate acoustic methods.

Key topics

Scope and definitions - Applies where each machine produced is assigned its own individual labelled noise value; definitions follow ISO 7574-1.

Statistical approach - Describes statistical procedures (used in a restricted sense) for estimating the declared value and for verifying compliance; statistical treatment is particularly relevant to estimating parameters such as uncertainty or correction factors (e.g., K).

Verification procedure - A practical method for checking whether an individual machine’s noise emission lies below its labelled value.

Measurement context - Assumes use of recognized acoustic measurement methods and facilities (reverberation/anechoic conditions as appropriate) and trained staff in a testing laboratory.

Limitations - The standard does not prescribe consequences or remedial actions if a machine fails verification.

Applications

Manufacturers declaring noise emission values on labels or technical data sheets for individual machines.

Accredited test laboratories performing conformity checks and noise measurements (sound power/pressure) to confirm labelled values.

Conformity assessment bodies and regulators that need a standardized statistical method for verification of declared noise values.

Acoustic consultants and procurement teams evaluating noise claims in purchasing or certification processes.

Practical use typically involves measuring sound power or sound pressure using established acoustics methods, applying the statistical verification procedure from this part of ISO 7574, and documenting compliance or non‑compliance of the individual machine with its labelled noise value.
