This standard specifies the additional requirements and tests for gas meters conforming to EN 1359, EN 12261, EN 12480, EN 14236 which have additional functionalities that form part of the meter or contained in an Additional Functionality Device. It also covers the additional requirements when the base meter replaces its mechanical index with an electronic index. Where the option of an integral valve is specified, this standard only gives requirements for gas meters having a maximum capacity of 10 m3/h. This document is applicable to 1st, 2nd and 3rd family gases according to EN 437. This document specifies the construction requirements for electronic components but communication protocols are dealt within other European standards, e.g. EN 13757. Note: This document covers connections to auxiliary devices but not the requirements for these devices. This 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.
