Electroacoustics - Sound level meters - Part 3: Periodic tests

IEC 61672-3:2013 describes procedures for periodic testing of time-weighting, integrating-averaging, and integrating sound level meters that were designed to conform to the class 1 or class 2 specifications of the second edition of IEC 61672-1. The aim of the standard is to ensure that periodic testing is performed in a consistent manner by all laboratories. The purpose of periodic testing is to assure the user that the performance of a sound level meter conforms to the applicable specifications of IEC 61672-1 for a limited set of key tests and for the environmental conditions under which the tests were performed. Periodic tests described in this edition of IEC 61672-3 apply to sound level meters for which the manufacturer claims conformance to the specifications of the second edition of IEC 61672-1. Periodic tests described in IEC 61672-3 apply to sound level meters for which the model has been, or has not been, pattern approved by an independent testing organization responsible for pattern approvals in accordance with the test procedures of the second edition of IEC61672-2. This second edition cancels and replaces the first edition published in 2006. This second edition constitutes a technical revision. The main changes with regard to the previous concern conformance to specifications which is now demonstrated when measured deviations from design goals do not exceed the applicable acceptance limits, and when the uncertainty of measurement does not exceed the corresponding maximum-permitted uncertainty, with both uncertainties determined for a coverage probability of 95 %. In this document, references to IEC 61672-1, IEC 61672-2, and IEC 61672-3 refer to the second editions unless stated otherwise. Procedures for the periodic testing of sound level meters designed to conform to the specifications of IEC 61672-1:2002 were given in IEC 61672-3:2006.

Electroacoustique - Sonomètres - Partie 3: Essais périodiques

La CEI 61672-3:2013 décrit les procédures relatives aux essais périodiques des sonomètres à pondération temporelle, des sonomètres intégrateurs-moyenneurs et des sonomètres intégrateurs conçus pour répondre aux spécifications de la classe 1 ou de la classe 2 de la CEI 61672-1. L'objet de la présente norme est de s'assurer que les essais périodiques sont effectués de manière cohérente par tous les laboratoires. Le but des essais périodiques est d'assurer à l'utilisateur que les performances d'un sonomètre répondent aux spécifications applicables de la CEI 61672-1, pour un nombre limité d'essais clé et pour les conditions d'environnement dans lesquelles ces essais ont été réalisés. Les essais périodiques décrits dans la CEI 61672-3 s'appliquent aussi aux sonomètres pour lesquels la conformité aux spécifications de la deuxième édition de la IEC 61672-1 a été déclarée par le fabricant. Les essais périodiques décrits dans la CEI 61672-3 s'appliquent aux sonomètres dont le modèle a été ou n'a pas été approuvé par un organisme d'essai indépendant, responsable des approbations de modèles conformément aux procédures d'essai de la deuxième édition de la CEI 61672-2. Cette deuxième édition annule et remplace la première édition parue en 2006. Cette deuxième édition constitue une révision technique. Les modifications techniques majeures suivantes par rapport à l'édition précédente concernent la conformité aux spécifications qui est maintenant démontrée lorsque les écarts mesurés par rapport aux valeurs nominales ne dépassent pas les limites d'acceptation applicables, et lorsque l'incertitude de mesure ne dépasse pas l'incertitude maximale autorisée correspondante, les deux incertitudes étant déterminées pour une probabilité de couverture de 95 %. Dans le présent document, les références aux CEI 61672-1, CEI 61672-2, et CEI 61672-3 s'entendent pour les deuxièmes éditions, sauf indication contraire. Les procédures pour réaliser les essais périodiques de sonomètres conçus pour être conformes aux spécifications de la CEI 61672-1:2002 ont été données dans la CEI 61672-3:2006.
