23、by NEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2003, and conflicting national standards shall be withdrawn at the latest by December 2004. It has been prepared in liaison with Techni
24、cal Committee CEN/TC 234 “Gas supply“. This standard is a part of a System Standard for plastics piping systems of a particular material for a specified application. There are a number of such System Standards. System Standards are based on the results of the work undertaken in ISO/TC 138 “Plastics
25、pipes, fittings and valves for the transport of fluids“, which is a Technical Committee of the International Organization for Standardization (ISO). They are supported by separate standards on test methods to which references are made throughout the System Standard. The System Standards are consiste
26、nt with general standards on functional requirements and on recommended practice for installation. EN 1555 consists of the following parts, under the general title Plastics piping systems for the supply of gaseous fuels Polyethylene (PE): Part 1: General (this standard) Part 2: Pipes Part 3: Fitting
27、s Part 4: Valves Part 5: Fitness for purpose of the system Part 7: Guidance for assessment of conformity (to be published as an CEN/TS).

31、components made from polyethylene (PE) and which is intended to be used for the supply of gaseous fuels. Requirements and test methods for components of the piping system are specified in EN 1555-2, EN 1555-3 and EN 1555-4. Characteristics for fitness for purpose are covered in EN 1555-5. prCEN/TS 1
32、555-7 gives guidance for assessment of conformity. Recommended practice for installation is given in EN 12007-2, prepared by CEN/TC 234.

33、ntrolled Copy, (c) BSI EN 1555-1:2002 (E) 5 1 Scope This part of EN 1555 specifies the general aspects of polyethylene (PE) piping 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 the oth
34、er parts of EN 1555 (see Foreword) it is applicable to PE pipes, fittings, and valves, their joints and to joints with components of other materials intended 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
35、 20 C as reference temperature. NOTE 1 For other operating temperatures, derating coefficients should be used, see EN 1555-5. EN 1555 covers a range of maximum operating pressures and gives requirements concerning colours and additives. NOTE 2 It is the responsibility of the purchaser or specifier t
36、o make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publicati
