Gas Infrastructure - Gas installation pipework with an operating pressure greater than 0,5 bar for industrial installations and greater than 5 bar for industrial and non-industrial installations - Part 1: Detailed functional requirements for design, materials, construction, inspection and testing
SIST EN 15001-1:2023

This European Standard specifies detailed functional requirements for the design, selection of materials, construction, inspection and testing of:
-   industrial gas installation pipework and assemblies with an operating pressure greater than 0,5 bar; and
-   non-industrial gas installation pipework (residential and commercial) with an operating pressure greater than 5 bar in buildings;
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 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 (all parts) 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 in buildings, EN 1775 applies.
For gas installations that do not fall within the scope of EN 1775 or other European Standards, this 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 (normal conditions). 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 LPG;
-   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 in the liquid state (e.g. between the storage vessel and any pressure regulator).
In this standard, all pressures are gauge pressures unless otherwise stated.
This standard has been harmonized to address the essential safety requirements of the Pressure Equipment Directive (PED, 2014/68/EU [formerly 97/23/EC]) relevant for the joining of gas installation pipework (assemblies) falling within the scope of the PED. These are listed in Annex ZA. However, "this Directive does not cover the assembly of pressure equipment on the site and under the responsibility of the user, as in the case of industrial installations" (PED, Preamble, 7th recital, last paragraph).
Although in this respect, the standard takes into account the essential safety requirements of the PED, no inference can be drawn from this as to whether or not the installation or parts of the installation falls within the scope of the PED. Reference should therefore be made to the PED and relevant national legislation.
This European Standard specifies common basic principles for gas supply systems. Users of this European Standard should be aware (...)

Gas infrastructure - Pipelines for maximum operating pressure up to and including 16 bar - Part 1: General functional requirements
SIST EN 12007-1:2013

This European Standard describes the general functional requirements for pipelines up to the point of delivery, and also for buried sections of pipework after the point of delivery, for maximum operating pressures up to and including 16 bar for gaseous fuels in accordance with EN 437:1993+A1:2009, Table 1. It applies to their design, construction, commissioning, decommissioning, operation, maintenance, renovation, extension and other associated works.
This European Standard does not apply to the materials, design, construction, testing and commissioning of gas infrastructures in use prior to the publication of this European Standard. However, this European Standard does apply to the operation, maintenance, renovation and extension of all gas infrastructures.
Specific functional requirements for polyethylene pipelines are given in EN 12007-2, for steel pipelines in EN 12007-3 and for the renovation of pipelines in EN 12007-4. Functional recommendations for pipework for buildings are given in EN 1775. Functional requirements for service lines are given in prEN 12007-5.
Functional requirements for pressure testing, commissioning and decommissioning are given in EN 12327.
Functional requirements for measuring systems are given in EN 1776.
Functional requirements for pressure regulating stations are given in EN 12186.
Functional requirements for pressure regulating installations are given in EN 12279.
Functional requirements for gas transmission are given in EN 1594.
This European Standard specifies common basic principles for gas infrastructure. 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. 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.
In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this European Standard, the national legislation/regulation should take precedence as illustrated in FprCEN/TR 13737-1.
FprCEN/TR 13737-1 gives:
-   clarification of all legislations/regulations applicable in a member state;
-   if appropriate, more restrictive national requirements;
-   a national contact point for the latest information.

Gas infrastructure - Pipelines for maximum operating pressure up to and including 16 bar - Part 5: Service lines - Specific functional requirements
SIST EN 12007-5:2025

This document describes the specific functional requirements for the transportation of gases (gaseous energy carriers) through service lines in addition to the general functional requirements of EN 12007 1 for:
a)   a maximum operating pressure (MOP) up to and including 16 bar;
b)   an operating temperature between −20 °C and +40 °C;
c)   gases and blends of gases which are in the gaseous state when conveyed in the gas pipeline infrastructure such as hydrogen, hydrogen rich, and methane rich gases, dimethyl ether (DME) and propane and butanes used for combustion and/or as feedstock, excluding steam and compressed air, where technical evaluation has ensured that operating conditions, constituents and properties of the gas do not affect the safe operation and maintenance of the service line.
It applies to their design, construction, commissioning, decommissioning, operation, maintenance, extension and other associated works including safety and environmental aspects. The service line is the physical asset comprising of pipework from the gas main branch saddle or top tee to the outlet of the distribution system operator’s nominated point(s) of delivery (for example: isolation valve, regulator, meter connection or combination of regulator and isolation valve).
This document does not apply retrospectively to installations before the publication date unless specifically stated.
Specific functional requirements for:
—   polyethylene pipelines are given in EN 12007 2;
—   steel pipelines are given in EN 12007 3;
—   polyamide (PA-U) pipelines are given in CEN/TS 12007 6;
—   pipework for buildings are given in EN 1775;
—   pressure regulating installations are given in EN 12279 or EN 12186;
—   pressure testing, commissioning and decommissioning are given in EN 12327;
—   safety management system (SMS) and pipeline integrity management system (PIMS) are given in EN 17649.
This document specifies common basic principles for gas infrastructure. Users of this document are expected to be aware that there can exist more detailed national standards and/or codes of practice in the CEN member countries. This document is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles.
In the event of terms of additional requirements in legislation/regulation than in this document, CEN/TR 13737 (all parts) illustrates these terms.
CEN/TR 13737 gives:
—   description of legislations/regulations applicable in a member state;
—   if appropriate, more restrictive national requirements;
—   a national contact point for the latest information.
