This European Standard specifies the requirements and tests for the construction, performance, safety and conformity of gas-volume electronic conversion devices associated to gas meters, used to measure volumes of fuel gases of the 1st and 2nd families according to EN 437. This European Standard is intended for type testing, the detailed relevant provisions of which are given in Annex A. Only three kinds of conversion are treated in this European Standard: conversion as a function of temperature only (called T conversion); conversion as a function of the pressure and of the temperature with constant compression factor (called PT conversion); conversion as a function of the pressure, the temperature and taking into account the compression factor (called PTZ conversion).
