This European Standard has been drafted as part of the work being undertaken by the European Standards Organisations (CEN/CENELEC/ETSI) under the Commission Mandate M/441. This standard utilises the six functionalities agreed by the Smart Meters Coordination Group (SM-CG) (see Annex C) as the basis for its additional functionalities. It is not necessary for the Additional Functionality Device (AFD) to incorporate all functions. This European Standard specifies the additional requirements and tests for gas meters with a maximum capacity of 40 m3/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 m3/h. Such gas valves are intended for interruption of the gas supply but do not replace any valve intended to isolate the gas supply. Communications for gas meters are outside the scope of this standard and are covered by the appropriate parts of EN 13757, which provide a number of protocols and transport layers for meter communications for Gas, Water and Heat meters.
