- This European Standard specifies the additional requirements and tests for gas meters with a maximum capacity of 40 m?/h and a maximum operating pressure of not exceeding 500 mbar, conforming to EN 1359, EN 12261, EN 12480, EN 12405 and EN 14236, which have battery powered devices providing additional functionalities that form part of the gas meter (hereafter referred to as meter) or contained in an Additional Functionality Device (AFD). It also covers the additional requirements when an electronic index is used rather that a mechanical one. Where the option of an integral valve to the meter is specified, this standard only gives requirements for meters having a maximum capacity not exceeding 10 m?/h. This European Standard is applicable to first, second and third family gases according to EN 437. This European Standard specifies the construction requirements for electronic components but communication protocols are dealt within other European Standards, e.g. appropriate parts of EN 13757. This European Standard covers connections to auxiliary devices but not the requirements for these devices. This European Standard applies to AFDs that are installed in locations with vibration and shocks of low significance and in: closed locations (indoor or outdoor with protection as specified by the manufacturer) with condensing or with non-condensing humidity, or, if specified by the manufacturer: open locations (outdoor without any covering) with condensing humidity or with non-condensing humidity, locations liable to temporary saturation, and in locations with electromagnetic disturbances corresponding to those likely to be found in residential, commercial buildings or similar buildings. This European Standard does not cover the changing of metrological software within the meter or the upload/download of metrological software. This European Standard only covers valves integral to the meter.
