18、EN. Attention is drawn to the possibility that some of the elements of 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 document supersedes ENV 13801:2000. The revision mainly consists in changing

19、the status from ENV to CEN/TR and the following minor changes: a) other materials than PP homopolymer mentioned in 5.1; b) update of symbols in Clause 3; c) mention of possible local regulations on fire and acoustics in Clause 4; d) reference of adhesives standards in 6.4. This Technical Report is o

20、nly a guidance document to be used mainly as a basis for preparing more specific manufacturers instructions. It is associated with standards for piping systems covering a particular thermoplastic material for a specified application. There are a number of such standards. It is based on the results o

21、f 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). This Technical Report is consistent with general standards on functional requirements and on recommended

22、practice for installation. PD CEN/TR 13801:2014CEN/TR 13801:2014 (E) 5 Introduction This Technical Report covers the recommended practice for installation of the thermoplastics piping systems for soil and waste discharge. The most important recommendations are expressed by the use of the imperative.

23、 These are strongly recommended. Guidance for installation is presented, e.g. by the use of “may” or “is recommended”, for consideration as a matter of judgement in each case. PD CEN/TR 13801:2014CEN/TR 13801:2014 (E) 6 1 Scope This Technical Report gives the recommended practice for installation of

24、 thermoplastics piping systems in the field of soil and waste discharge (low and high temperature) inside buildings (marked with “B”) and of soil and waste discharge systems for both inside buildings and buried in ground within the building structure (marked with “BD”). This Technical Report provide

25、s material dependent installation techniques but it is important that the general installation practice as given in the relevant parts of EN 12056 for B application are taken into account in manufacturers instructions, subject to any applicable national and/or local regulations. This Technical Repor

26、t is applicable to thermoplastics pipes and fittings as specified in the associated standards EN 1329-1 1 (PVC-U), EN 1451-1 2 (PP), EN 1453-1 3 (PVC-U with structured-wall pipes), EN 1455-1 4 (ABS), EN 1519-1 5 (PE), EN 1565-1 6 (SAN+PVC) and EN 1566-1 7 (PVC-C), their joints and to joints with com

27、ponents of other plastics and non-plastics materials intended to be used for the following purposes: a) soil and waste discharge pipework for the conveyance of domestic waste waters (low and high temperature); NOTE 1 See Clause 4 for waste discharge temperature limits. b) ventilating pipework associ

28、ated with a); c) rainwater pipework within the building structure (see Figure 1, key 16). It is applicable to pipes and fittings, marked with “B”, which are intended to be used above ground only, and to pipes and fittings, marked “BD”, which are intended to be used above and buried in ground within

29、the building structure. NOTE 2 Only those components as specified in the relevant associated standard with nominal outside diameters equal to or greater than 75 mm (marked with “BD”) are intended for use buried in ground within the building structure. The term “within building structure” covers all

30、gravity discharge pipework within a building, including the elements installed below the slab and buried in the ground. If specified in the relevant associated standard, this Technical Report also covers soil and waste discharge pipework fixed externally onto the building (see Figure 1, key 17). It

31、is not applicable to pipework that passes under the building without any connection from the discharge system. NOTE 3 According to the associated standards, for external above ground soil and waste discharge, additional requirements depending on the climate, will be agreed between the manufacturer a

32、nd the user. According to the associated standards, components conforming to other standards on plastic piping systems may be used with pipes and fittings conforming to a given associated standard, if they conform to the requirements for joint dimensions and functional requirements of the given asso

33、ciated standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
