European foreword
This document (EN 15001-2:2023) has been prepared by Technical Committee CEN/TC 234 “Gas
supply”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by August 2023, and conflicting national standards shall
be withdrawn at the latest by August 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 15001-2:2008.
A list of the significant changes compared to EN 15001-2:2008 can be found in Annex A, Table A.1.
The scope of this revised standard is extended with biomethane and vaporized LNG gases. This
standard is not designed for various mixtures of natural gas and hydrogen which may be allowed in the
different member states.
With respect to hydrogen there are proposals to inject hydrogen (H2) from renewable sources into the
natural gas network. Investigations have been conducted to evaluate the impact. According to EN 16726
at present it is not possible to specify a limiting hydrogen value which would generally be valid for all
parts of the European gas infrastructure.
There is a complete suite of functional standards prepared by CEN/TC 234 “Gas infrastructure” to cover
all parts of the gas supply system from the input of gas to the transmission system up to the inlet
connection of the gas appliances, whether for domestic, commercial or industrial purposes.
In preparing this document, a basic understanding of gas supply by the user has been assumed.
In the event of conflicts in terms of more restrictive requirements in national legislation/regulation
with the requirements of this standard, national legislation/regulation takes precedence as illustrated
in CEN/TR 13737.
NOTE CEN/TR 13737 contains:
— clarification of relevant legislation/regulations applicable in a country;
— if appropriate, more restrictive national requirements;
— national contact point for the latest information.
Gas supply systems are complex and the importance on safety of their construction and use has led to
the development of very detailed codes of practice and operating manuals in the member countries.
These detailed statements embrace recognized standards of gas engineering and the specific
requirements imposed by the legal structures of the member countries.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.

European foreword
This document (prEN 15001-2:2017) has been prepared by Technical Committee CEN/TC 234 “Gas
supply”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 15001-2:2008.
A list of the significant changes compared to EN 15001-2:2008 can be found in Annex A, Table A.1.
The scope of this revised standard is extended with biomethane and vaporized LNG gases. This
standard is not designed for various mixtures of natural gas and hydrogen which may be allowed in the
different member states.
With respect to hydrogen there are proposals to inject hydrogen (H2) from renewable sources into the
natural gas network. Investigations have been conducted to evaluate the impact. According to EN 16726
at present it is not possible to specify a limiting hydrogen value which would generally be valid for all
parts of the European gas infrastructure.
There is a complete suite of functional standards prepared by CEN/TC 234 “Gas infrastructure” to cover
all parts of the gas supply system from the input of gas to the transmission system up to the inlet
connection of the gas appliances, whether for domestic, commercial or industrial purposes.
In preparing this standard, a basic understanding of gas supply by the user has been assumed.
In the event of conflicts in terms of more restrictive requirements in national legislation/regulation
with the requirements of this standard, national legislation/regulation takes precedence as illustrated
in CEN/TR 13737.
NOTE CEN/TR 13737 contains:
— clarification of relevant legislation/regulations applicable in a country;
— if appropriate, more restrictive national requirements;
— national contact point for the latest information.
Gas supply systems are complex and the importance on safety of their construction and use has led to
the development of very detailed codes of practice and operating manuals in the member countries.
These detailed statements embrace recognized standards of gas engineering and the specific
requirements imposed by the legal structures of the member countries.

prEN 15001-2:2017 (E)
1 Scope
This European Standard specifies detailed functional requirements for the commissioning, operation
and maintenance of
— industrial gas installations and assemblies with an operating pressure greater than 0,5 bar; and of
— non-industrial gas installations (residential and commercial) with an operating pressure greater
than 5 bar,
starting from the outlet of the network operator’s point of delivery up to the inlet connection to the gas
appliance; normally the inlet isolation valve. This European Standard also covers the pipework to the
inlet connection of a gas appliance that is not included within the scope of the appliance standard.
NOTE 1 The use of the term installation and pipework is interchangeable.
Apart from the exceptions stated below, this standard applies to gas installations operating at ambient
temperatures between –20 °C and 40 °C and operating pressures up to and including 60 bar. For
operating conditions outside these limitations, reference should additionally be made to EN 13480 for
metallic pipework.
For industrial gas installations up to and including 0,5 bar and for non-industrial (residential and
commercial) gas installations up to and including 5 bar EN 1775 applies.
For gas installations that do not fall within the scope of EN 1775 or other European Standards, this
European Standard applies.
In this European Standard, the term “gas“ refers to combustible gases, which are gaseous at 15 °C and
1 013 mbar absolute atmospheric pressure. These gases are commonly referred to as manufactured gas,
natural gas or Liquefied Petroleum Gas (LPG). They are also referred to as first, second or third family
gases as classified in EN 437:2003+A1:2009., Table 1 The given values are considered as normal
conditions for all volumes given in this standard.
This European Standard is applicable to installation pipework for the carriage of:
— processed, non-toxic and non-corrosive natural gas according to EN 437:2003+A1:2009 and
EN 16726 “Gas infrastructure - Quality of gas - Group H”;
— vaporized LNG;
— biomethane, complying with EN 16723-1;
— vaporized LNG.
NOTE 2 The specification of vaporized LNG is equal to that of natural gas as classified in
EN 437:2003+A1:2009.
This European Standard does not cover pipework for hydrogen rich gases that fall outside the
definitions within EN 437:2003+A1:2009. LPG storage vessels (including all ancillaries fitted directly to
storage vessels) are excluded. Also excluded are LPG installations and sections of LPG installations
operating at vapour pressure (e.g. between the storage vessel and its pressure regulator).
In this European Standard, all pressures are gauge pressures unless otherwise stated.
This European Standard specifies common basic principles for gas supply systems. Users of this
European Standard should be aware that more detailed national standards and/or code of practice may
exist in the CEN member countries.

oSIST prEN 15001-2:2017
prEN 15001-2:2017 (E)
This European Standard is intended to be applied in association with these national standards and/or
codes of practice setting out the above-mentioned basic principles.
For gas installations within the scope of this standard, national legislation and regulations are meant to
be taken into account.
Functional requirements for design, selection of materials, construction, inspection and testing of
industrial gas installations and assemblies with an operating pressure greater than 0,5 bar and of gas
installations greater than 5 bar in buildings and areas intended for residential, commercial, public and
mixed uses are described in EN 15001-1.
Generally, additional safety precautions may be necessary where non odorized gas is used. For non-
industrial purposes, the gas should be odorized.
