This document specifies requirements on the development and implementation of a Safety Management System (SMS) and a Pipeline Integrity Management System (PIMS). The SMS is applicable for system operators of a gas infrastructure. The PIMS is applicable for system operators of gas infrastructure with a maximum operating pressure (MOP) over 16 bar.

This document refers to all activities and processes related to safety aspects and performed by system operators of a gas infrastructure, including those activities entrusted to contractors. It includes safety-related provisions on operation of the gas infrastructure

The described SMS is applicable to infrastructure for the conveyance of processed, non-toxic and non-corrosive natural gas according to EN ISO 13686 and non-conventional gases such as biomethane and hydrogen and substitute natural gases including injected gases.

This document covers also EN 16726, which specifies gas quality characteristics, parameters and their limits, for gases classified as group H that are to be transmitted, injected into and from storages, distributed and utilized. The requirements and test methods for biomethane at the point of entry into natural gas network are covered by EN 16723-1.

This document can apply for gas infrastructure conveying gases of the 3rd gas family as classified in EN 437.

Specific requirements for occupational health and safety are excluded from this document. For these, national legislation and other European and/or international standards, e.g. OHSAS 18001, apply.

This document specifies common basic principles for gas infrastructure. It is important that users of this document are aware that more detailed national standards and/or codes of practice may exist 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 conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this document, the national legislation/regulation takes precedence as illustrated in CEN/TR 13737 (all parts).

NOTE 1 CEN/TR 13737 (all parts) contains:

— clarification of relevant legislation/regulations applicable in a country;

— if appropriate, more restrictive national requirements;

— national contact points for the latest information.

This document specifies the requirements and test methods for verification for hose assemblies with vapour recovery for delivery systems on petrol filling stations.

The hose assemblies with vapour recovery for delivery systems on petrol filling stations need to be capable of withstanding anticipated mechanical, thermal and chemical stressing and be resistant to the combustible liquids used in these applications as well as their vapour and vapour air mixtures. It is imperative that the assemblies be constructed in such a way that actions during normal operation cannot give rise to dangerous electrostatic charges nor that there will be any reduction in the performance of the vapour recovery.

The assemblies are intended for use at ambient temperatures between –30 °C and +55 °C for normal temperature class and –40 °C and +55 °C for low temperature class at a working pressure ≤ 16 bar1.

Hoses can be constructed from rubber or thermoplastic elastomer (TPE) and this document specifies the requirements for three types of hoses in two grades and two classes of hose assemblies for measured fuel dispensing systems, including oxygenated fuels (≤15 % oxygenated compounds) with internal vapour recovery tubing or hose.

NOTE This document is not applicable to multi chamber fuel dispensing hoses.

As part of the certification of a new dispenser, testing of fuel samples in accordance with EN 228 are carried out at least eight weeks after the first use of the equipment to avoid unrepresentative sulphur content results.
