Gas infrastructure - Gas installation pipework with an operating pressure greater than 0,5 bar for industrial installations and greater than 5 bar for industrial and non-industrial installations - Part 2: Detailed functional requirements for commissioning, operation and maintenance

Publication date:   Sep 30, 2009

Scope

This European Standard specifies detailed functional requirements for the commissioning, operation and maintenance of
• industrial gas installations and assemblies with an operating pressure greater than 0,5 bar and of
• non-industrial installations (residential and commercial) with an operating pressure greater than 5 bar,
starting from the outlet of the network operator’s point of delivery up to the inlet connection to the gas appliance; normally the inlet isolation valve. This European 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 additionally be made to EN 13480 for metallic pipework.
For industrial gas installations up to and including 0,5 bar and for non-industrial (residential and commercial) gas installations up to and including 5 bar EN 1775 applies.
For gas installations that do not fall within the scope of EN 1775 or other European Standards, this European Standard applies.
In this European 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 Liquefied Petroleum Gas (LPG). They are also referred to as first, second or third family gases (see table 1 of EN 437:2003).
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 (e.g. between the storage vessel and its pressure regulator).
In this European Standard, all pressures are gauge pressures unless otherwise stated.
For gas installations within the scope of this standard, national legisl
