Gas supply systems - 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
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 gas 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 pipework to the inlet connection of a gas appliance that is not included within the scope of the appliance standard.
NOTE The use of the term installation and pipework is interchangeable.
Apart from the exceptions stated below, 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 as classified in Table 1 of EN 437:2003+A1:2009. The given values are considered as normal conditions for all volumes given in this standard.
This European Standard is applicable to installation pipework for the carriage of:
- processed, non-toxic and non-corrosive natural gas according to EN 437:2003+A1:2009 and EN 16726 -Gas infrastructure - Quality of gas - Group H”,
- vaporized LNG,
- biomethane, complying with EN 16723-1,
- vaporized LNG.
NOTE The specification of vaporized LNG is equal to that of natural gas as classified in EN 437:2003+A1:2009.
This European Standard does not cover pipework for hydrogen rich gases that fall outside the definitions within EN 437:2003+A1:2009. 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.
This European Standard specifies common basic principles for gas supply systems. Users of this European Standard should be aware that more detailed national standards and/or code of practice may exist in the CEN member countries.
This European Standard is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles.
For gas installations within the scope of this standard, national legislation and regulations have to be taken into account.
Functional requirements for 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 gas installations greater than 5 bar in buildings and areas intended for residential, commercial, public and mixed uses are described in EN 15001-1.
Generally, additional safety precautions may be necessary where non odorized gas is used. For non-industrial purposes, the gas should be odorized.

Ta standard se uporablja za plinske naprave, ki delujejo pri temperaturah okolice med −20 °C in 40 °C ter pri obratovalnih tlakih do vključno 60 barov. Za obratovalne pogoje zunaj teh omejitev se je treba dodatno sklicevati na standard EN 13480 za kovinske cevovode.
Za industrijske plinske napeljave do vključno 0,5 bara in za neindustrijske (stanovanjske in poslovne) plinske napeljave do vključno 5 barov v stavbah se uporablja standard EN 1775.
Za plinske napeljave, ki ne spadajo na področje uporabe standarda EN 1775 ali drugih evropskih standardov, velja ta evropski standard.
V tem standardu se izraz »plin« nanaša na gorljive pline, ki so plinasti pri 15 °C in absolutnem atmosferskem tlaku 1013 mbar (normalni pogoji). Ti plini se običajno imenujejo industrijski plin, zemeljski plin ali utekočinjeni naftni plin (LPG). Imenujemo jih tudi plini prve, druge ali tretje plinske družine (glej preglednico 1 standarda EN 437:2003).
Posode za shranjevanje utekočinjenega naftnega plina (LPG) (vključno z vsemi pomožnimi napravami, nameščenimi neposredno na posode za shranjevanje) so izključene. Prav tako so izključene naprave za LPG in deli naprav za LPG, ki delujejo pri parnem tlaku (npr. med posodo za shranjevanje in regulatorjem tlaka).
V tem evropskem standardu so vsi tlaki merilni tlaki, razen če ni drugače navedeno.
Za plinske naprave, ki spadajo v področje uporabe tega standarda, se uporablja nacionalna zakonodaja.
