IEC 60079-29-1:2007

Specifies general requirements for construction and testing and describes the test methods that apply to portable, transportable and fixed apparatus for the detection and measurement of flammable gas or vapour concentrations with air. The apparatus, or parts thereof, are intended for use in potentially explosive atmospheres and in mines susceptible to firedamp.

Specifies requirements for group II (as defined in part 1) portable, transportable and fixed apparatus for the detectino and measurement of combustible gas or vapour concentrations with air. The apparatus, or parts thereof, may be installed or used in potentially explosive atmospheres, other than mines susceptible to firedamp (i.e. group I). This standard is restricted to apparatus intended for the detection and measurement of combustible gas or vapour concentrations with air up to 100% lower explosive limit (LEL).

Specifies requirements for group II (as defined in part 1) portable, transportable and fixed apparatus for the detection and measurement of combustible gas or vapour concentrations with air. The apparatus, or parts thereof, may be installed or used in potentially explosive atmospheres, other than mines susceptible to firedamp (i.e. group I). This standard is restricted to apparatus intended for the detection and measurement of volume ratios of combustible gas or vapour in air in volume fractions from 0% to 100%.

Specifies requirements for group I (as defined in part 1) portable, transportable and fixed apparatus for the detection and measurement of methane concentrations in mine air. The apparatus, or parts thereof, are intended for use in mines susceptible to firedamp. The requirements and test methods applicable to the apparatus covered by this standard are specified in part 1. This standard is restricted to apparatus intended for the detection and measurement of volume ratios of methane in air from a volume fraction of 0 % up to a volume fraction of 100 %.

Specifies requirements for group I (as defined in part 1) portable, transportable and fixed apparatus for the detection and measurement of methane concentrations in mine air. The apparatus, or parts thereof, are intended for use in mines susceptible to firedamp. The requirements and test methods applicable to the apparatus covered by this standard are specified in part 1. This standard is restricted to apparatus intended for the detection and measurement of volume ratios of methane in air from a volume fraction of 0 % up to, but not exceeding, a volume fraction of 5%.

IEC 60079-29-1:2016 spécifie les exigences générales pour la construction, les essais et l’aptitude à la fonction, et décrit les méthodes d’essai qui s’appliquent aux matériels portables, transportables et fixes pour la détection et le mesurage des concentrations de gaz ou de vapeurs inflammables dans l’air. Les matériels, ou parties de ceux-ci, sont destinés à être utilisés dans des atmosphères explosives et dans les mines grisouteuses. Cette deuxième édition de l'IEC 60079-29-1 annule et remplace la première édition de la série IEC 60079-29-1:2007. Cette édition constitue une révision technique. Reportez-vous à l'avant-propos du document pour une liste changements importants entre cette édition et l'édition précédente. Mots clés: détection et le mesurage des concentrations de gaz ou de vapeurs inflammables dans l’air, atmosphères explosives, mines grisouteuses, explosion potentiel Le contenu des feuilles d'interprétation 1 et 2 (2019-04) a été pris en considération dans cet exemplaire (en anglais seulement).
