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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not

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 International Standard 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, this International
Standard 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 are based on the observation that four
main parameters affect user safety and system compatibility.

4 General construction requirements
a) There are two different sizes of refuelling systems, size 1 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 ⌀ 7,8 mm ± 0,2 mm.
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 ⌀ 12 mm ± 0 2mm.
Also, the profile of the two different sizes is so different that no cross connection between the sizes is
possible.
b) Working pressure (= 1,25 times service pressure). All nozzles and receptacles are designed to have
a working pressure of:

c) 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
International Standard. In addition, all nozzles shall be tested according to the following frequency
use classifications, as applicable.
— 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.
d) Training. Operator. Training required is in accordance with national requirements.
4.1 Compressed blended fuels nozzles and receptacles shall be well fitted and manufactured in
accordance with good engineering practice. All construction requirements can be met by either the
construction specified in this International Standard or another construction that gives at least equivalent
performance.
4.2 Compressed blended fuels nozzles and receptacles shall be:
— designed to minimize the possibility of incorrect assembly;
— designed to be secure against displacement, distortion, warping, or other damage;
— constructed to maintain operational integrity under normal and reasonable conditions of handling
and usage.
4.3 Nozzles and receptacles shall be manufactured of materials suitable and compatible for use with
compressed blended fuels at the pressure and the temperature ranges to which it will be subjected.
4.3.1 The temperature ranges shall be:
Table 1 — Temperature ranges
Location on board
Location a Location b
Cold −40 °C to 120 °C −40 °C to 85 °C
Moderate −20 °C to 120 °C −20 °C to 85 °C
Location a — Inside the engine compartment in case of internal combustion engine vehicle. The
receptacle shall be installed far from either heat or sparking sources and in a vented area.
Location b — Elsewhere in case of internal combustion engine vehicle.

4.4 Compressed blended fuels nozzles and receptacles shall be constructed out of materials which have
to be proven for the intent of withstanding a blended fuels mixture at the given pressures, temperatures,
and contents of the fuel that can be expected in this system.
4.5 Separate external three-way valves shall be constructed and marked so as to indicate clearly the
open, shut, and vent positions.
4.6 Compressed blended fuels nozzles and receptacles shall be operated either to connect or disconnect
without the use of tools.
4.7 Jointing components shall provide gas tight sealing performance.
Unless otherwise specified, all tests shall be conducted using dry hydrogen, helium, or blends of nitrogen
with a minimum 5 % of hydrogen. Test shall be performed by qualified personnel and appropriate safety
measures shall be taken. The dew point of the test gas at the test pressure shall be at the temperature at
which there is no icing, or hydrate or liquid formation. The dew point of the test gas at the test pressure
shall be at the temperature at which there is no icing, or hydrate or liquid formation.
5 Nozzles
5.1 Nozzles shall be one of three types as described in a) to c). (See also Annex A)
a) Type 1, which is a nozzle for use with dispensing hoses that remain fully pressurized at dispenser
shutdown. The nozzle shall not allow gas to flow until a positive connection has been achieved. The
nozzle shall be equipped with an integral valve or valves, incorporating an operating mechanism
which first stops the supply of gas and safely vents the trapped gas before allowing the disconnection
of the nozzle from the receptacle. The operating mechanism shall ensure the vent valve is in the
open position before the release mechanism can be operated and the gas located between the
nozzle shut-off valve and the receptacle check valve is safely vented prior to nozzle disconnection
(see 10.2).
b) Type 2, which is a nozzle for use with dispensing hoses that remain fully pressurized at dispenser
shutdown. A separate three-way valve connected directly, or indirectly, to the inlet of the nozzle is
required to safely vent trapped gas prior to nozzle disconnection. The nozzle shall not permit the
flow of gas if unconnected. Venting is required prior to disconnection of the nozzle (see 10.2).
c) Type 3, which is a nozzle for use with dispensing hoses which are automatically depressurised
(0,5 MPa and below) at dispenser shutdown (see 10.2).
In addition, nozzles shall be classified in terms of cycle life as follows:
— Class A - This class specifies high frequency use, with a cycle life of 100 000.
— Class B - This class specifies low frequency use, with a cycle life of 20 000.
5.2 Venting or de-pressurization of all nozzle types is required prior to disconnection. Disconnection of
all nozzles shall be capable of being accomplished in accordance with 10.2.
5.3 The method for attaching the nozzle to the fuel dispensing system hose shall not rely on the joint
threads between the male and female threads for sealing, such as conical threads.
5.4 The three-way valve vent port of Type 1 and Type 2 nozzles shall be protected from the ingress of
foreign particles and fluid which would hamper the operation of the valve. It has to be considered that the
vented gas has to be lead into a safe direction.
5.5 The portions of a nozzle which are held by the user for connection or disconnection can be thermally
insulated or it shall be ensured that no abnormal dangerous temperatures can be transferred to the user.
