CSA Preface

This is the first edition of ANSI/CAN/CSA-ISO 12617, Road vehicles — Liquefied natural gas (LNG) refuelling connector — 3,1 MPa connector, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 12617 (first edition, 2015-03-15; corrected version 2016-01-15). At the time of publication, ISO 12617:2015 is available from ISO in English only. CSA Group will publish the French version when it becomes available from ISO.


This International Standard specifies liquefied natural gas (LNG) refuelling nozzles and receptacles constructed entirely of new and unused parts and materials for road vehicles powered by LNG. An LNG refuelling connector consists of, as applicable, the receptacle and its protective cap (mounted on the vehicle) and the nozzle. This International standard is applicable only to such devices designed for a maximum working pressure of 3,4 MPa (34 bar) to those using LNG as vehicle fuel and having standardized mating components.

NOTE All references to pressures given in megapascals and bar (1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2) are to be considered gauge pressures, unless otherwise specified.
