This document covers the design and manufacturing, installation and testing, operation and maintenance of vehicle fuelling appliances (VFA) for domestic fuelling of vehicles with compressed natural gas (CNG). This document is applicable to VFAs having the following technical limits: – maximum compressing capacity: 20 Nm3/h (NTP); – maximum internal storage volume for outdoor installation: 400 l; – maximum gas outlet pressure: 200 bar at 15 Ā°C; This document is applicable to VFAs supplied with natural gas as defined in local applicable gas composition regulations or EN 16723 2, or with other gases meeting these requirements including biomethane, upgraded coal-bed methane (CBM) and gas from liquefied natural gas (LNG) vaporizer (on-site or off-site). This document applies to VFAs not incorporating gas outlet metering systems.
