(Main)Performance of portable leak detectors and of room monitors for halogenated refrigerants
Performance of portable leak detectors and of room monitors for halogenated refrigerants
The purpose of this European Standard is to qualify the performance of portable sniffing leak detectors and room monitors for halogenated refrigerants. These leak detectors are designed for the detection of CFC, HCFC, HFC and PFC halogenated gases, and their detection limit is checked with a calibration leak or calibration gas.
Leistung von mobilen Leckdetektoren und Raumüberwachungsgeräten für halogenierte Kältemittel
Diese Europäische Norm hat den Zweck, die Leistung von mobilen Schnüffel-Leckdetektoren und
Raumüberwachungsgeräten für halogenierte Kältemittel zu bestimmen. Diese Leckdetektoren sind für den
Nachweis von FCKW-, HFCKW-, HFKW- und FKW-Gasen bestimmt, ihre Nachweisgrenze wird mit einem
Kalibrierleck oder Kalibriergas geprüft.
Performances des détecteurs de fuite portables et des contrôleurs d'ambiance de fluides frigorigènes halogénés
La présente Norme européenne a pour objet la définition des performances des détecteurs de fuite portables de type « renifleurs » et des contrôleurs d'ambiance des fluides halogénés. Ils sont conçus pour détecter des gaz halogénés de type CFC, HCFC, HFC et PFC, et leur limite de détection est vérifiée à l'aide d'une fuite d’étalonnage ou d'un gaz d’étalonnage.
Lastnosti premičnih javljalnikov puščanja in sobnih nadzornih naprav za halogenska hladila
Namen tega evropskega standarda je opredeliti lastnosti premičnih javljalnikov puščanja in sobnih nadzornih naprav za halogenska hladila. Ti javljalniki puščanja so izdelani za zaznavanje halogenskih plinov CFC, HCFC, HFC in PFC, pri čemer se meja zaznavanja preveri s kalibracijskim puščanjem ali kalibracijskim plinom.

The hydrogen is completely substituted. 3.5 gas concentration ratio in weight or in volume of a given gas to the total weight or volume of the gas mixture NOTE 1 The concentration is dimensionless and is designated either with ppm (m/m) = parts per million (mass) or
ppm (V/V) = parts per million (volume). NOTE 2 ppm: statement of concentration for gases; parts per million expressed in volume per volume ratio. 3.6 leakage rate gas flow through a fissure, an orifice or aperture of specified size NOTE 1 The usual leakage rate unit is gram per year (g/a), see Annex A (informative). NOTE 2 The gas flow channels are some micrometers of diameter and have a large length/diameter ratio. SIST EN 14624:2012
