Electroacoustics - Sound level meters - Part 2: Pattern evaluation tests

IEC 61672-2:2013 provides details of the tests necessary to verify conformance to all mandatory specifications given in IEC 61672-1 for time-weighting sound level meters, integrating-averaging sound level meters, and integrating sound level meters. Pattern-evaluation tests apply for each channel of a multi-channel sound level meter, as necessary. Tests and test methods are applicable to class 1 and class 2 sound level meters. The aim is to ensure that all laboratories use consistent methods to perform pattern-evaluation tests. This second edition cancels and replaces the first edition published in 2003. This second edition constitutes a technical revision, the main technical changes with regard to the previous edition 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 pattern-evaluation testing of sound level meters designed to conform to the specifications of IEC 61672-1:2002 were given in IEC 61672-2:2003.

Elektroakustik - Schallpegelmesser - Teil 2: Baumusterprüfungen

Electroacoustique - Sonomètres - Partie 2: Essais d'évaluation d'un modèle

La CEI 61672-2:2013 donne des détails concernant les essais nécessaires pour vérifier la conformité à toutes les spécifications obligatoires données dans la CEI 61672-1 pour les sonomètres à pondération temporelle, les sonomètres intégrateurs-moyenneurs, et les sonomètres intégrateurs. Les essais d'évaluation d'un modèle s'appliquent, si nécessaire, à chaque canal d'un sonomètre à plusieurs canaux. Les essais et les méthodes d'essai sont applicables aux sonomètres de classe 1 et de classe 2. Le but est de s'assurer que tous les laboratoires utilisent des méthodes cohérentes pour effectuer les essais d'évaluation d'un modèle. Cette seconde édition annule et remplace la première édition parue en 2003. Elle constitue une révision technique qui inclut des modifications techniques majeures concernant démonstration de la conformité aux spécifications. Elle 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 ce 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 d'évaluation d'un modèle de sonomètres conçus pour être conformes aux spécifications de la CEI 61672-1:2002 ont été données dans la CEI 61672-2:2003.

Elektroakustika - Merilniki zvočne jakosti - 2. del: Preskusi z ocenjevanjem vzorcev (IEC 61672-2:2013)

Ta del standarda IEC 61672 navaja podrobnosti glede preskusov, potrebnih za preverjanje skladnosti z vsemi obveznimi specifikacijami, podanimi v standardu IEC 61672-1 za merilnike časovno vrednotene zvočne jakosti, zvokomere z integracijskim povprečenjem in merilnike integracijske zvočne jakosti. Preskusi z ocenjevanjem vzorcev se po potrebi uporabijo za vsak kanal večkanalnega merilnika zvočne jakosti. Preskusi in preskusne metode se uporabljajo za merilnike zvočne jakosti razreda 1 in 2. Cilj je zagotoviti uporabo skladnih metod pri preskušanju z ocenjevanjem vzorcev v vseh laboratorijih.
