Gas Supply Systems - Gas installation pipework with an operating pressure greater than 0,5 bar for industrial, commercial and non-domestic gas installations - Part 1: Detailed functional requirements for design, materials, construction, inspection and testing prEN 15001-1

Scope

This standard specifies detailed functional requirements for the design, selection of materials, construction, inspection and testing of industrial gas installations and assemblies with an operating pressure greater than 0,5 bar and of non-industrial gas installations with an operating pressure greater than 5 bar in buildings and areas intended for domestic, commercial, public and mixed uses, starting from the gas supplier's behind the network operator's point of delivery up to the inlet connection to the gas appliance; normally the inlet isolation valve. This standard also covers the inlet connection to the gas appliance comprising of the pipework that does not fall within the scope of the appliance standard.
This standard applies to gas installations operating at ambient temperatures between -20°C and 40°C and operating pressures up to and including 60 bar. For operating conditions outside these limitations, reference should be made to EN 13480 for metallic pipework.
For industrial gas installations up to and including 0,5 bar and for non-industrial (domestic and commercial) gas installations up to and including 5 bar in buildings and areas intended for domestic, commercial, public and mixed use, EN 1775 applies.
For gas installations that do not fall within the scope of EN 1775 or other European standards, this standard applies.
In this standard, the term "gas" refers to combustible gases, which are gaseous at 15°C and 1 013 mbar absolute atmospheric pressure. These gases are commonly referred to as manufactured gas, natural gas or Liquidfied Petroleum Gas (LPG). They are also referred to as first, second or third family gases (see table 1 of EN 437:1993).
LPG storage vessels (including all ancillaries fitted directly to storage vessels) are excluded. Also excluded are LPG installations and sections of LPG installations operating at vapour pressure.
In this standard, all pressures are gauge pressures unless otherwise stated.
