La présente partie de l'ISO 7574 donne un guide pour la détermination des valeurs annoncées des émissions acoustiques des machines et équipements étiquetés individuellement, c'est-à-dire que chaque machine produite a la valeur de sa grandeur d'émission acoustique annoncée individuellement. Elle spécifie également une méthode de contrôle de la conformité de l'émission acoustique d'une machine individuelle ou d'un équipement avec la valeur annoncée. La présente partie de l'ISO 7574 ne traite pas des conséquences qui s'ensuivent dans le cas où la valeur déclarée n'est pas confirmée comme étant vérifiée pour une machine individuelle.

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
EN 27574-2 / ISO 7574-2 is useful for:
- 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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bodies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take patt in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 7574/2 was prepared by Technical Committee ISO/TC 43,
Acoustics.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless othetwise stated.
