This document defines the minimum requirements to ensure the interoperability of hydrogen refuelling points, including refuelling protocols that dispense gaseous hydrogen to road vehicles (e.g. Fuel Cell Electric Vehicles) that comply with legislation applicable to such vehicles. The safety and performance requirements for the entire hydrogen fuelling station, addressed in accordance with existing relevant European and national legislation, are not included in this document. This document applies to hydrogen refuelling points dispensing gaseous hydrogen to vehicles compliant with UN R134 (Regulation No. 134), UN R134 or Regulation (EC) No 79/2009. NOTE 1 Guidance on considerations for hydrogen fuelling stations is provided in ISO 19880 1:2020. NOTE 2 Units used in this document follow SI (International System of Units).
