BS EN ISO 16380:2018

What is ISO 16380 - Blended fuels refuelling connector about?  

16380 applies to compressed blended fuels vehicle nozzles and receptacles hereinafter referred to as devices, constructed entirely of new, unused parts and materials. Compressed blended fuels fuelling connection nozzles consist of the following components, as applicable: 

• Receptacle and protective cap (mounted on vehicle) (see Clause 7) 
• Nozzle (mounted on dispenser side) (see Clause 5) 

ISO 16380 applies to devices which have a service pressure of 20 MPa, 25 MPa, and 35 MPa hereinafter referred to in this International Standard as [see 9.1 c)]: 

• Size 1: M200, M250, and M350; 
• Size 2: N200 and N250.  

ISO 16380 refers to service pressures of 20 MPa, 25 MPa, and 35 MPa for size 1 and 20 MPa and 25 MPa for size 2. 

ISO 16380 applies to devices with standardised mating components (see 5.8 and 7.7). 

ISO 16380 applies to connectors which 

• Prevent blended fuels vehicles from being fuelled by dispenser stations with working pressures higher than the vehicle fuel system working pressure 
• Allow blended fuels vehicles to be fuelled by dispenser stations with working pressures equal to or lower than the vehicle fuel system working pressure 
• Allow blended fuels vehicles to be fuelled by dispenser stations for compressed natural gas 
• Allow blended fuels vehicles to be fuelled by compressed natural gas dispenser stations with working pressures equal to or lower than the vehicle fuel system working pressure 
• Prevent blended fuels vehicles size 1 being refuelled on blended fuels dispenser stations equipped with a size 2 nozzle and vice versa 
• Prevent natural gas vehicles from being fuelled by blended fuels station, and dispensers, and 
• Prevent pure hydrogen vehicles from being fuelled by blended fuels station dispensers 

ISO 16380  is applicable to mixtures of hydrogen from 2 % to 30 % in volume and compressed natural gas containing: 

• Natural gas in accordance with ISO 154031 and ISO 154032 
• Pure hydrogen in accordance with ISO 146871 or ISO/TS 146872 

Who is ISO 16380 - Blended fuels refuelling connector for? 

ISO 16380 on blended fuels refuelling connector is useful for: 

• Manufacturers of nozzles and receptacles 
• Automobile industry 
• Petroleum industry 

Why should you use ISO 16380 - Blended fuels refuelling connector?  

A nozzle certified to ISO 16380 will be functionally compatible from a safety and performance perspective with all listed receptacles of compatible profile and system pressure. Similarly, a receptacle certified to ISO 16380 will be functionally compatible from a safety and performance perspective with all listed nozzles of compatible profile and system pressure. 

As there can eventually be many different kinds of nozzles and receptacles available from a variety of manufacturers which, for safety reasons, shall all be compatible with each other, ISO 16380 specifies a series of receptacle profiles. These standard profiles incorporate the design specifications (mating materials, geometry, and tolerances) which can be considered in the certification of a submitted nozzle or receptacle. 

The construction and performance of nozzles and receptacles as specified in ISO 16380 are based on the observation that four main parameters affect user safety and system compatibility.
