Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the
subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 16380 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 25, Vehicles
using gaseous fuel, JWG5 Fuel system components of vehicles propelled by gaseous hydrogen or by blends
of hydrogen and methane

Introduction
A nozzle certified to this International Standard 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 this standard will be functionally compatible from a safety and performance perspective with all
listed nozzles of compatible profile and system pressure.
A there may 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, this International Standard
specifies a series of receptacle profiles. These standard profiles incorporate the design specifications (mating
materials, geometry and tolerances) which may be considered in the certification of a submitted nozzle or
receptacle.
The construction and performance of nozzles and receptacles are based on the observation that four main
parameters affect user safety and system compatibility.
1) There exist two different sizes of refuelling systems. As there is the size1 and size 2.
Size 1 should suit the need of smaller vehicles with a limited tanks size. Therefore the flow diameter
is limited by the inner front diameter of the receptacle – in this case Ø7.8mm +-0.2mm.
Size 2 should suit the need of commercial vehicles like busses and trucks. Therefore the flow
diameter is limited by the inner front diameter of the receptacle – in this case Ø12mm+-0.2mm.
Also the profile of the two different sizes is so different that no cross connection between the sizes is
possible.
2) Working Pressure (=1.25 times Service Pressure). All nozzles and receptacles are designed to have
a working pressure of:
Code Service Pressure Working Pressure
Size 1
M200 20 MPa 25 MPa
M250 25 MPa 31.25 MPa
M350 35 MPa 43.75 MPa
Size 2
N200 20 MPa 25 MPa
N250 25 MPa 31.25 MPa
3) Design Life. Frequency of use is the second parameter to be considered. Since frequency of use will
differ with the nozzle/receptacle application (i.e., public sector, fleet employee and residential), all
receptacles will be tested at 10 000 connect/disconnect cycles for compliance with this standard. In
addition, all nozzles shall be tested according to the following frequency use classifications, as
applicable:
ISO/DIS 16380
 Class A Nozzle - This class specifies high frequency use, with a cycle life of 100 000. This
equates to approximately 100 fills per day for three years.
 Class B Nozzle - This class specifies medium frequency use, with a cycle life of 20 000 cycles.
This equates to approximately 10 fills per day for five years.
4) Training. Operator training required is in accordance with national requirements.
