Omfang

1.1 This standard specifies the general recommendations for the design, construction, testing, commissioning, operation and maintenance of installation pipework, that is the pipework between the point of delivery of the gas and the inlet connection to the gas appliance. This standard specifies common basic principles for gas installation pipework. Users of this European standard should be aware that more detailed national standards and/or codes of practice may exist in the CEN member countries. This standard is intended to be applied in association with these national standards and/or codes of practice setting out the above mentioned basic principles. This standard is applicable to installation pipework having a maximum operating pressure (MOP) less than or equal to 5 bar. This standard is applicable to new installation pipework as well as to replacements of, or extensions to, existing installation pipework. This standard does not contain recommendations for the laying of buried pipework. For more information, reference should be made to prEN 12007-1, prEN 12007-2 and prEN 12007-3. For more information on gas pressure regulating installations, reference should be made to prEN 12279. For more information on gas metering systems, reference should be made to prEN 1776. 1.2 This standard is applicable to installation pipework supplied from gas distribution systems. LPG installations supplied directly from storage vessels are excluded. 1.3 In this standard the term 'gas' refers to combustible gases, which are gaseous at 15 °C and 1 013 mbar. These gases, generally odorized for safety reasons, are commonly referred to as manufactured gas, natural gas or liquefied petroleum gases (LPG). They are also referred to as first, second or third family gases (see table 1 of EN 437 : 1993). In this standard, all pressures are gauge pressures.
