Les hottes d’évacuation avec et sans registres d’évacuation sont couvertes par ces exigences. 1.2 Les hottes d’évacuation avec et sans registres d’évacuation automatiques déclenchés en cas de feu sont couvertes…

IEC 62841-2-7:2024 deals with the safety of electric motor-operated hand-held spray guns for non-flammable materials. The rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. The rated input is not more than 3 700 W. The limits for the applicability of this standard for battery tools are given in K.1 and L.1. This standard deals with the…

This document gives general guidance for the sampling and gas chromatographic analysis of compressor oil in biomethane or compressed natural gas (CNG). The compressor oil mass fraction is determined by sampling on coalescing filters under defined operational conditions (the two first cubic meters of gas referring to standard conditions, delivered at a refuelling station). Compressor oils are…

Le présent document fournit des recommandations générales relatives au prélèvement et à l'analyse par chromatographie en phase gazeuse de l'huile de compresseur présente dans le biométhane ou dans le gaz naturel comprimé (GNC). La fraction massique de l'huile de compresseur est déterminée par prélèvement sur des filtres coalescents dans des conditions d'exploitation définies (…

IEC 61189-2-808:2024 describes the thermal transient method to characterize the thermal resistance of an assembly consisting of a heat source (e.g. power device), an attachment material (e.g. solder) and a dielectric layer with electrode. This method is suitable to determine the thermal resistance of materials and assembly methods as well as to optimize the thermal flux to a heat sink. NOTE:…
