Over deze norm
This European standard specifies detailed functional requirements for the commissioning, operation and maintenance of industrial gas installations operating above 0,5 bar and domestic or commercial gas installations above 5 bar. For non-industrial [domestic and commercial] gas installations up to 5 bar, EN 1775 applies. This European standard also applies to gas installations up to 5 bar not within the scope of EN 1775 or other European standards, as well as to mixed installations [industrial and non-industrial]. The inlet connection to the appliance is normally the inlet isolation valve but can include the pipework downstream of this valve- if this pipework is not covered by the appliance standard, then this standard applies. The requirements for design, materials, construction, inspection and testing of gas installations over 0,5 bar and domestic or commercial gas installations over 5 bar are given in part 1 (WI 00234026) of this standard. In this standard the term 'gas' refers to combustible gases, which are gaseous at 15 °C and 1,013 mbar absolute pressure. These gases, are commonly referred to as manufactured gas, natural gas or liquid petroleum gases (LPG). They are also referred to as first, second or third family gases (see table 1 of EN 437: 1993). LPG storage tanks (including all ancillaries fitted directly to the tanks) are excluded see prEN 14570. 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.
