Annotation of standard text IEC 61577-2-ed.2.0 :
IEC 61577-2:2014 describes the specific requirements for instruments measuring the activity concentration of airborne 222Rn and 220Rn outdoors, in dwellings and in workplaces including underground mines. This standard applies practically to all types of electronic measuring instruments that are based on either spot or continuous measurements. The different types of instrumentation used for measurements are stated in IEC 61577-1. This new edition includes the following significant technical changes with respect to the previous edition: - addition of new requirements and tests concerning performance; - harmonization of the requirements and tests concerning performance with other standards in this area. LIEC 61577-2:2014 decrit les exigences specifiques relatives aux instruments destines au mesurage de lactivite volumique des 222Rn et 220Rn en suspension dans lair a lexterieur, dans les habitations et sur les lieux de travail, y compris dans les mines souterraines. En pratique, la presente norme sapplique a tous les types dinstruments de mesure electroniques utilisant des methodes basees sur des prelevements instantanes ou encontinu. Les differents types dinstrumentation utilises pour les mesures sont indiques par lIEC 61577-1. Cette nouvelle edition inclut les modifications techniques significatives suivantes par rapport a ledition precedente: - ajout de nouvelles exigences et de nouveaux essais concernant la performance; - harmonisation des exigences et des essais, concernant la performance, avec dautres normes dans ce domaine.
