Specification for portable electrical apparatus designed to measure draught and gas pressure of heating appliances and systems

This document specifies the requirements and test methods concerning, in particular the construction, safety, and fitness for purpose, as well as the capability and marking of a hand-held battery powered pressure and leakage measurement instrument, hereafter referred to as "pressure meters", for gas pipework in buildings, gas pipes of appliances and draught in chimneys. NOTE Areas of application can be supply pressure of gas appliances, nozzle pressure of gas appliances (see relevant instruction manuals of gas appliances) as well as strength test, tightness test and fitness test of gas pipework as defined in EN 1775 and relevant national standards for gas pipework in buildings, and draught measurement in chimneys of heating appliances. This document covers pressure meters with the capability of - use with air, natural gas, liquid petroleum gas (LPG), hydrogen and mixtures of natural gas and hydrogen, - measuring pressure in units of bar, mbar, Pa, hPa, kPa, MPa, H20, mm H2O or PSI, - measuring leakage rate in l/h, - withstanding the every-day working environment encountered by installation and service engineers in domestic, commercial, or industrial premises. Such pressure meters might be capable of - being switchable between units by the user, - storing and/or transmitting said measurements to a remote user.

Spécification pour les appareils électriques portatifs conçus pour mesurer la pression du tirage et des gaz dans les conduits d’évacuation des appareils et systèmes de chauffage

Le présent document spécifie les exigences et les méthodes d’essai relatives, notamment, à la construction, à la sécurité et à l’aptitude à l’usage, ainsi qu’à la performance et au marquage des appareils de mesure de pression et d’étanchéité portatifs à alimentation autonome, ci-après nommés « manomètres », destinés à être utilisés dans les canalisations de gaz des bâtiments, les tuyauteries de gaz des appareils et les conduits à tirage des cheminées. NOTE La pression d’alimentation des appareils à gaz, la pression à la buse des appareils à gaz (consulter les manuels d’utilisation relatifs auxdits appareils), de même que les essais de résistance mécanique, d’étanchéité et d’aptitude à l’usage des canalisations de gaz, tels que définis dans l’EN 1775 et dans les normes nationales pertinentes applicables aux canalisations de gaz dans les bâtiments, ou encore le mesurage du tirage dans les conduits de cheminée des appareils de chauffage, comptent parmi les domaines d’application possibles. Le présent document couvre les manomètres répondant aux critères suivants : - utilisation possible avec l’air, le gaz naturel, le gaz de pétrole liquéfié (GPL), l’hydrogène et des mélanges de gaz naturel et d’hydrogène ; - lecture possible des mesures de pression dans les unités suivantes : bar, mbar, Pa, hPa, kPa, MPa, H2O, mm H2O ou PSI ; - mesure possible du débit de fuite, en l/h ; - capacité de résistance aux environnements de travail des locaux domestiques, commerciaux ou industriels dans lesquels les ingénieurs d’installation et de maintenance interviennent au quotidien. Il est conseillé que lesdits manomètres puissent également : - être raccordés successivement à différentes unités par l’utilisateur, - enregistrer les mesures effectuées et/ou les transmettre à un utilisateur distant.
