EN 60079-20-1:2010

Explosive atmospheres - Part 20-1: Material characteristics for gas and vapour classification - Test methods and data

IEC 60079-20-1:2010 provides guidance on classification of gases and vapours. It describes a test method intended for the measurement of the maximum experimental safe gaps (MESG) for gas- or vapour-air mixtures under normal conditions of temperature and pressure so as to permit the selection of an appropriate group of equipment. The tabulated values of chemical and engineering properties of substances are provided to assist engineers in their selection of equipment to be used in hazardous areas. This first edition of IEC 60079-20-1 cancels and replaces the first edition of IEC 60079-1-1(2002), the second edition of IEC 60079-4 (1975), its amendment 1(1995) and its complement: IEC 60079-4A (1970), the first edition of IEC/TR 60079-12 (1978) and the first edition of IEC 60079-20 (1996). It constitutes a technical revision.

Atmosphères explosives - Partie 20-1: Caractéristiques des substances pour le classement des gaz et des vapeurs - Méthodes et données d'essai

La CEI 60079-20-1:2010 donne des lignes directrices pour le classement des gaz et des vapeurs. Elle décrit une méthode d'essai destinée à mesurer les interstices expérimentaux maximaux de sécurité (IEMS) des mélanges de gaz ou de vapeurs et d'air dans des conditions normales de température et de pression de manière à permettre le choix d'un groupe approprié de matériels. Les valeurs des propriétés chimiques et physiques des substances données dans les tableaux sont destinées à aider les ingénieurs pour le choix des matériels utilisés dans des zones dangereuses. Cette première édition de la CEI 60079-20-1 annule et remplace la première édition de la CEI 60079-1-1 (2002), la deuxième édition de la CEI 60079-4 (1975), son amendement 1 (1995) et son complément: la CEI 60079-4A (1970), la première édition du CEI/TR 60079-12 (1978) et la première édition de la CEI 60079-20 (1996). Elle constitue une révision technique.

Eksplozivne atmosfere - 20-1. del: Lastnosti materiala - Razvrstitev plinov in hlapov, preskusne metode in podatki (IEC 60079-20-1:2010)

Ta del IEC 60079 zagotavlja vodilo za razvrstitvi plinov in hlapov. Opisuje preskusno metodo za merjenje maksimalnih preskusnih varnih vrzeli (MESG) za mešanice plin-zrak ali hlap-zrak pod običajnimi pogoji  temperature in pritiska, da je omogočena izbira primerne skupine opreme.  Metoda ne upošteva možnih učinkov ovir na varnih vrzelih. Ta standard prav tako opisuje preskusno metodo, namenjeno za uporabo pri določitvi temperature samovžiga kemično čistih hlapov ali plina v zraku pri atmosferskem tlaku.    Tabelirane vrednosti kemičnih in tehničnih lastnosti substanc so podane v pomoč inženirjem pri njihovi izbiri opreme za uporabo na nevarnih področjih. Pričakuje se, da bodo občasno objavljeni nadaljnji podatki, in sicer, ko bodo na voljo rezultati preskusov, opravljenih v več državah.    Področje uporabe teh podatkov je bilo izbrano s posebnim ozirom na uporabo opreme na nevarnih območjih, pri čemer so se upoštevale standardne meritvene metode.
