This document includes Amendment 1, approved by CEN on 2011-07-15. This document supersedes EN 12666-1:2005. !The main changes in the

29、 revised document are: relevant test methods are changed from EN to ISO versions; two new dimensions, 560 mm and 710 mm are introduced; a new ring stiffness class SN 16 is introduced; updating of the references in Clause 2; introduction of S-series in 3.3; introduction of S-series, a new footnote a)

30、 and a new NOTE in Table 3; introduction of a new watertightness test for fabricated fittings; deletion of Long Term Performance of TPE seals Table 12 and 10.3; corrections of misprints in Tables 13 and 14 Marking of pipes and fittings; introduction of a new informative Annex B Product standards of

32、f this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This European Standard is a part of a system standard for plastics piping systems of a particular material for a specified application. There are a num

33、ber of such system standards. System standards are based on the results of the work undertaken in ISO/TC 138 “Plastics 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 s

34、tandards on test methods to which references are made throughout the system standard. The system standards are consistent with general standards on functional requirements and on recommended practice for installation. EN 12666 consists of the following parts, under the general title Plastics piping

BS EN 12666-1:2005+A1:2011EN 12666-1:2005+A1:2011 (E) 5 1 Scope This Part of EN 12666 specifies the requirem

38、ents for pipes, fittings and the system of polyethylene (PE) piping systems intended to be used for non-pressure underground drainage and sewerage outside the building structure (application area code “U“), and non-pressure underground drainage and sewerage for both buried in the ground within the b

39、uilding structure (application area code “D“) and outside the building structure. This is reflected in the marking of products by “U“ and “UD“. It also specifies the test parameters for the test methods referred to in this European Standard. This European Standard covers a range of nominal sizes, a

40、range of pipe series/stiffness classes and gives recommendations concerning colours. NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selection from these aspects, taking into account their particular requirements and any relevant national regulations and install

41、ation practices or codes. In conjunction with CEN/TS 12666-21it is applicable to PE pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for buried piping systems for non-pressure drainage and sewerage. This European Standard

42、 is applicable to PE pipes with or without an integral socket. The fittings can be manufactured by injection-moulding or be fabricated from pipes and/or mouldings. This European Standard is applicable to PE pipes and fittings for the following types of joints: elastomeric ring seal joints; butt fuse

43、d joints; electrofusion joints; mechanical joints. NOTE 2 Requirements and limiting values for application area code “D“ are given in Tables 3, 6 and Table 12. NOTE 3 Pipes, fittings and other components conforming to any of the plastics product standards listed in the bibliography may be used with

44、pipes and fittings conforming to this European Standard, provided they conform to the requirements for joint dimensions given in Clause 6 and to the requirements of Table 8 and Table 12. 2 Normative references The following referenced documents are indispensable for the application of this European
