UNE-EN 15399:2020

This European Standard specifies requirements on the development and implementation of a safety management system for operators of gas network with a maximum operating pressure up to and including 16 bar according to EN 12007 (all parts).

This European Standard refers to all activities and processes related to safety aspects and performed by a DSO including those activities entrusted to contractors.

The described safety management system is applicable to infrastructure for the distribution of processed, non-toxic and non-corrosive gas of the 2nd gas family as classified in EN 437, including injected gases from non-conventional sources.

NOTE 1 Gases from non-conventional resources can be bio methane, hydrogen, shale gas, synthetic gases and others.

This European Standard can also apply for gas infrastructure conveying only gases from non-conventional sources, such as bio methane grids or gases of the 3rd family as classified in EN 437.

For safety management systems for gas transmission network EN 16348 applies.

Occupational health and safety is excluded from this European standard. National legislation and other European and/or international standards, e.g. OHSAS 18001, apply.

This European Standard specifies common basic principles for gas infrastructure. Users of this 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 standard, the national legislation/regulation takes precedence as illustrated in CEN/TR 13737 (all parts).

NOTE 2 CEN/TR 13737 (all parts) contains:

clarification of relevant legislation/regulations applicable in a country;
