EN 60079-29-4:2010

Explosive atmospheres - Part 29-4: Gas detectors - Performance requirements of open path detectors for flammable gases

IEC 60079-29-4:2009 specifies performance requirements of equipment for the detection and measuring of flammable gases or vapours in ambient air by measuring the spectral absorption by the gases or vapours over extended optical paths, ranging typically from one meter to a few kilometres. Such equipment measures the integral concentration of the absorbing gas over the optical path in units such as LFL.meter for flammable gases. This standard supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of this standard shall take precedence.

Atmosphères explosives - Partie 29-4: Détecteurs de gaz - Exigences d'aptitude à la fonction des détecteurs de gaz inflammables à chemin ouvert

La CEI 60079-29-4:2009 spécifie les exigences d'aptitude à la fonction des matériels de détection et de mesure des gaz ou vapeurs inflammables dans l'air ambiant dont le principe de fonctionnement est basé sur la mesure de l'absorption spectrale par les gaz ou vapeurs sur des chemins optiques étendus, généralement sur une étendue comprise entre un mètre et quelques kilomètres. Ce type de matériel mesure la concentration intégrale des gaz absorbants sur le chemin optique en unités telles que le LII mètre pour les gaz inflammables. Cette norme complète et modifie les exigences générales de la CEI 60079-0. Lorsqu'une exigence de cette norme entre en conflit avec une exigence de la CEI 60079-0, l'exigence de la présente norme prévaut.

Eksplozivne atmosfere - 29-4. del: Javljalniki plina - Zahteve za delovanje javljalnikov vnetljivih plinov z odprto merilno potjo (IEC 60079-29-4:2009)

Ta del IEC 60079-29 opredeljuje zahteve za delovanje opreme za javljanje in merjenje vnetljivih plinov ali par v zunanjem zraku z merjenjem spektralne absorbcije plinov in par po razširjenih optičnih poteh, ki segajo od enega metra do nekaj kilometrov. Takšna oprema meri celotno koncentracijo absorpcijskega plina po optični poti v enotah, kot je meter LFL (spodnja meja vnetljivosti) za vnetljive pline.
