They are supported by separate standards on test methods to which references are made throughout the System Standard. The System Standards are consistent with general standards on functional requirements

DIN EN 1555-3:2013-01 EN 1555-3:2010+A1:2012 (E) 6 Introduction The System Standard, of which this is Part 3, specifies the requirements for a piping system and its components made from polyethylene (PE) and which is intended to be used for the supply of gaseous fuels. Requirements and tes
32、t methods for material and components, other than fittings, are specified in EN 1555-1, EN 1555-2 and prEN 1555-4 9. Characteristics for fitness for purpose are covered in EN 1555-5. CEN/TS 1555-7 2 gives guidance for assessment of conformity. Recommended practice for installation is given in EN 120
33、07-2:2000 1 prepared by CEN/TC 234. This part of EN 1555 covers the characteristics of fittings. DIN EN 1555-3:2013-01 EN 1555-3:2010+A1:2012 (E) 7 1 Scope This !European Standard“ specifies the characteristics of fusion fittings made from polyethylene (PE) as well as of mechanical fittings for pipi
34、ng systems in the field of the supply of gaseous fuels. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with Parts 1, 2, 4 and 5 of EN 1555, it is applicable to PE fittings, their joints and to joints with components of PE and other materials i
35、ntended to be used under the following conditions: a) a maximum operating pressure, MOP, up to and including 10 bar 1); b) an operating temperature of 20 C as reference temperature. NOTE 1 For other operating temperatures, derating coefficients should be used; see EN 1555-5. EN 1555 (all parts) cove
36、rs a range of maximum operating pressures and gives requirements concerning colours and additives. NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulati
37、ons and installation practices or codes. This European Standard is applicable for fittings of the following types: c) electrofusion socket fittings; d) electrofusion saddle fittings; e) spigot end fittings (for butt fusion using heated tools and electrofusion socket fusion); f) mechanical fittings.
38、The fittings can e.g. be in the form of couplers, equal and reduced tees, reducers, bends or caps. 2 Normative references !The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
