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 a method for determining the resistance to cracking of steel pipes in sour service. This test method employs a full-scale test specimen consisting of a short length of pipe (a ‘full ring’), sealed at each end to contain the sour test environment within. The test method applies to any pipe; seamless, longitudinally welded (with or without filler), helical welded, and to girth welds between pipes. NOTE 1 The specimen is usually a pipe but can also consist of flange neck or section of a bend, or other tubular component or a combination of the above. NOTE 2 This test method can also be used for corrosion resistant alloys (CRAs). The method utilizes ovalization by mechanical loading to produce a circumferential stress, equal to the target hoop stress, at two diametrically opposite locations on the inside surface of the test specimen. The test specimen is then subjected to single sided exposure to the sour test environment. NOTE 3 The test also allows measurement of hydrogen permeation rates.
