BS EN 12007-5:2024

This standard BS EN 12007-5:2024 Gas infrastructure. Pipelines for maximum operating pressure up to and including 16 bar is classified in these ICS categories:

• 23.040.01 Pipeline components and pipelines in general

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.
