3、EN 1401-1:1998 which is withdrawn. The UK participation in its preparation was entrusted by Technical Committee PRI/88, Plastics piping systems and components, to Subcom-mittee PRI/88/1, Thermoplastics piping systems and components for non-pressure applications.A list of organizations represented on
4、 this subcommittee can be obtained on request to its secretary.The responsible UK technical committee offers the following information in respect of the contents of this standard.1. Selection and application of stiffness classesBS EN 1401-1:2009 specifies three classes of pipes and fittings of diffe
5、ring stiffness, designated SN 2, SN 4 and SN 8 (see Table 4 and Table 6).From the viewpoint of installation, the SN 8 or SN 4 classes have to be used if the system is to be installed in accordance with BS EN 1610 or BS 5955-6, in order to achieve the intended resistance to long-term deformation.If i
6、t is intended to use the other, less stiff (SN 2), class of pipe or fitting, the installation should first be subject to a structural design soil load calculation and the installation technique modified to suit the results of that calculation. The appropriate calculation method is given in the Natio
7、nal Annex for BS EN 1295-1. The E modulus for the material should be taken as 3,000 MPa and 1,500 MPa for the short-term and long-term values respectively.Amendments/corrigenda issued since publicationDate Comments 31 October 2009 National foreword revisedReference material and further guidance on p

9、4514 and in addition the Building Regulations 2000 (amended 2002) Approved Document H1 (Diagram 2 and Clauses 1.17 and 1.26). When pipe conforming to EN 1401 is perforated for drainage applications, the perforations should additionally meet the requirements for UPVC in accordance with BS 4660, given

This European Stan
31、dard 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 pipes, fittings and valves for the transport of
32、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 consistent with general standards on functional requirem
33、ents and on recommended practice for installation. EN 1401 consists of the following Parts, under the general title Plastics piping systems for non-pressure underground drainage and sewerage Unplasticized poly(vinyl chloride) (PVC-U) Part 1: Specifications for pipes, fittings and the system (the pre
34、sent standard) Part 2: Guidance for assessment of conformity (under revision) BS EN 1401-1:2009EN 1401-1:2009 (E) 5 Part 3: Guidance for installation (ENV) According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this E

36、ted Kingdom. BS EN 1401-1:2009EN 1401-1:2009 (E) 6 1 Scope This Part of EN 1401 specifies the requirements for solid wall pipes, fittings and the system of unplasticized poly(vinyl chloride) (PVC-U) piping systems in the field of non-pressure underground drainage and sewerage: a) outside the buildin
37、g structure (application area code “U“) and b) both buried in ground within the building structure (application area code “D“) and outside the building. 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 Europe
38、an Standard. This European Standard covers a range of nominal sizes, a range of pipes and fittings series and a range of 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,
39、 taking into account their particular requirements and any relevant national regulations and installation practices or codes. In conjunction with prCEN/TS 1401-2 1 and ENV 1401-3 2 it is applicable to PVC-U pipes and fittings, their joints and to joints with components of other plastics and non-plas
40、tics materials intended to be used for buried piping systems for non-pressure underground drainage and sewerage. This European Standard is applicable to non foamed PVC-U pipes without a socket as well as pipes with an integral socket. The fittings can be manufactured by injection-moulding or be fabr
41、icated from pipes and/or mouldings. Requirements and limiting values for application area code “D“ are given in Table 4, Table 6, Table 13 and Table 15. NOTE 2 Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex C can be used with pipes and fittin
42、gs conforming to this European Standard, provided they conform to the requirements for joint dimensions given in Clause 6 and to the requirements of Table 15. 2 Normative references The following referenced documents are indispensable for the application of this document.
