6、lication of stiffness classesThis document specifies four classes of pipes and fittings of differing stiffness, designated SN16, SN 8, SN 4 and SN 2 (see Table 6).From the viewpoint of installation, it is recommended that SN16, SN 8 or SN 4 classes are used if the system is to be installed in accord
7、ance with national codes of practice for installation in order to achieve the intended resistance to long-term deformation.If the other, less stiff (SN 2), class of pipe or fitting is intended for use then it is recommended that the installation is first subjected to a structural design soil load ca

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
