ISO 16380:2014/Amd 1:2016 is an important amendment to the international standard ISO 16380:2014, which specifies the requirements for refuelling connectors used with blended gaseous fuels in road vehicles. Published by the International Organization for Standardization (ISO), this amendment updates critical aspects of the refuelling connector design, testing protocols, and material standards to ensure enhanced safety, compatibility, and performance in fueling systems utilizing compressed gaseous fuel blends.
This amendment targets connectors for refuelling systems handling mixed gaseous fuels under different pressures and temperatures, providing clear technical improvements to facilitate reliable and secure fueling operations globally.
Connector Material Requirements The amendment removes certain prescriptive clauses on injector and receptacle materials to align with evolving technology and material testing procedures.
Refuelling Connector Dimensions Updated dimensions and sealing surface specifications are provided for various connector sizes (M200, M250, M350). These figures include precise parameters for o-ring seals, surface finish, and hardness to maintain optimal sealing and durability.
Pressure Testing Protocols Testing pressures have been revised upward for accuracy in performance evaluation:
Technical Illustrations New figures replace previous diagrams detailing connector sealing zones, key component exclusions, and measurement tolerances to ensure manufacturers and testers have precise engineering guidance.
ISO 16380:2014/Amd 1:2016 is essential for stakeholders engaged in the design, manufacture, and testing of compressed gaseous fuel refuelling connectors used in road vehicles. Its practical applications include:
Automotive Industry Manufacturers of CNG (Compressed Natural Gas) and other gaseous fuel vehicles use the standard to design compatible and reliable refuelling connectors that meet global safety and performance criteria.
Fueling Station Equipment Equipment suppliers and operators of fuel dispensing stations benefit from standardized connector interfaces, enabling interoperability and minimizing refuelling hazards.
Regulatory Compliance Transportation authorities and safety regulators utilize this amendment to benchmark product safety certification, helping enforce secure fueling infrastructure.
Research and Development Laboratories and engineering teams leverage updated testing pressure regimes and material recommendations to innovate improved fuel delivery technologies.
These related standards complement ISO 16380 by addressing broader aspects of gaseous fuel systems, including tank specifications, fueling procedures, and safety protocols.
