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. In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this standard, the national legislation/regulation shall take precedence as illustrated in CR 13737:2001. This standard applies ç to residential, commercial gas installations (non industrial gas installations) having a maximum operating pressure (MOP) less than or equal to 5 bar. ç to industrial gas installations having a maximum operating pressure (MOP) less than or equal to 0,5 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 EN 12007-1, EN 12007-2 and EN 12007-3. For more information on gas pressure regulating installations, reference should be made to EN 12279. For more information on gas metering systems, reference should be made to EN 1776. This standard is applicable to installation pipework supplied from gas distribution systems and LPG installations supplied from storage vessels. Excluded are single appliance LPG installations achieved by a flexible appliance connector from a LPG storage vessel. 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). In this standard, all pressures are gauge pressures, unless otherwise stated. At the time of preparation of this standard, new pipe materials and jointing techniques are being developed or are already authorized for use in some member states. Any requirements additional to the requirements of this standard put in place in member states shall be identified in CR13737. It is important to ensure that designers and installation operatives are trained in the correct methods of application of each system as prepared by its supplier/manufacturer. This standard will be reviewed and amended as necessary to take account of such additional requirements.
