This EU standard is applicable for transporting gas via onshore high pressure steel pipeline infrastructures where:
-   onshore: from the point where the pipeline first crosses what is normally accepted as battery limit between onshore and offshore and not located within commercial or industrial premises as an integral part of the industrial process on these premises except for any pipelines and facilities supplying such premises. This European Standard also applies to a pipeline system with a starting point onshore, also when parts of the pipeline system on the mainland subsequently cross fjords, lakes etc.
-   high pressure: gas with a maximum operating pressure over 16 bar and a design temperature between −40 °C and 120 °C
-   steel pipeline infrastructure: a steel pipeline infrastructure consists of pipeline components such as pipes, valves, couplings and other equipment. Pipeline components in scope are restricted to components made of unalloyed or low alloyed carbon steel and joined by welds, flanges or mechanical couplings.
-   gas: non-toxic and non-corrosive natural gas, biomethane gas, hydrogen gas and mixtures of these gasses where technical evaluation has ensured that operating conditions or constituents or properties of the gas do not affect the safe operation of the pipeline.
Gas infrastructures covered by this European Standard begin after the gas producer's metering station. The functional demarcation of the pipeline system within a plant area will be determined from case to case. Generally speaking, this will be directly after the first isolating valve of the metering installation.
This European Standard also describes the mechanical requirements for pipework in stations with a maximum operating pressure greater than 16 bar.
Welding requirements are described in EN 12732. Functional requirements for stations are given in EN 1776, EN 1918-5, EN 12186, and EN 12583. Requirements for safety management and pipeline integrity management are given in EN 17649.
This European Standard specifies common basic principles for gas infrastructures. Users of this European Standard should be aware that there may exist more detailed national standards and codes of practice 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 principles.
This European Standard does not apply to existing pipelines, in use prior to the publication of this European Standard, nor to modifications to existing pipelines, except for the adaptation of the pipelines for the use of hydrogen and admixtures with hydrogen.
In the event of conflicts in terms of more restrictive requirements in the national legislation/regulation with the requirements of this European Standard, the national legislation/regulation takes precedence as illustrated in CEN/TR 13737 (all parts).
Reference is made in this European Standard to relevant European and other recognised standards for products used to construct and operate gas infrastructures.

This document gives the definitions and specifies the minimum requirements for injection moulded, extruded, compression moulded and thermoformed thermoplastics cuboid shaped boxes, including integral components, used in underground systems for retention, detention, storage and transportation of non-potable water (e.g. storm water) and manufactured from polyethylene (PE), polypropylene (PP) or unplasticized polyvinylchloride (PVC-U). The boxes are intended for buried underground use, e.g. in landscape, pedestrian or vehicular traffic areas. In the case of retention and detention systems, the main purpose of the boxes is to retain water, for later infiltration in the ground or for later use in non-potable applications (irrigation, cleaning, sanitary facilities, etc.) or to retain water during a storm, transferring it in a controlled way to the public storm water network. Applications include commercial, residential, agricultural and highway drainage, including installation under parking lots and roadways. Product performance is determined by a combination of material specification, product design and manufacturing process. A box can either be factory-assembled or site-assembled from different components. The boxes are intended to be used as elements in a modular system where the manufacturer has provided a clearly documented method specifying how the components are assembled to create a complete retention, detention, storage and transportation system. The boxes are installed as one or more horizontal layers on a firm foundation and embedded with fill around and above the complete system. NOTE Non-load bearing component(s) can be manufactured by various methods (e.g. extrusion, injection moulding, rotational moulding, compression moulded, thermoforming and low-pressure injection moulding) and are not within the scope of this document.

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   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 Table 1 of EN 437:2003+A1:2009. 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   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.
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 have 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.

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.
