Gas infrastructure - Pipelines for maximium operating pressure up to and including 16 bar - Part 5: Service lines - Specific functional requirements
 N EN 12007-5

Annotation

This European Standard describes the specific functional requirements for 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.

It applies to their design, construction, commissioning, decommissioning, operation, maintenance, extension and other associated works. 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).

The ownership and operation responsibility can vary between member states. The extent of the service line can differ in each member state. To illustrate this, the various points of deliveries are indicated in Figure 1. Consult Figure 1 (A/B/C/D/E) and member state regulations and standards.

NOTE The valve at point A is not necessarily utilised by each member state.

Specific functional requirements for:

— polyethylene pipelines are given in EN 12007-2.

— steel pipelines are given in EN 12007-3.

— pipework for buildings are given in EN 1775.
