10、mmittee PRI/88/1, Thermoplastic piping systems and components for non-pressure applications. It supersedes the 1983 edition, which is now withdrawn. The major changes between this revision and the previous edition as amended are as follows. a) The conventional products of the 36, 43, 56, 110 and 160
11、 sizes have been withdrawn as these products are now covered by BS EN 1329-1:2000. b) Where possible, reference has been made to the methods of test as described in BS EN 1329-1:2000. Attention is drawn to the provisions of the Health and Safety at Work etc. Act 1974 1, and the need to ensure that a
12、ppropriate precautions are taken to ensure the safety of personnel when carrying out the methods of test required by this standard. Annex A and Annex B are normative. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible
13、 for the correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

26、s which may be produced from thermoplastics other than unplasticized PVC. The requirements for the utilization of non-virgin materials shall be as specified in Annex A of BS EN 1329-1:2000. 3.2 Weather resistance When tested using the method described in Annex A, there shall be no visible change in
27、colour between the exposed and shaded parts of the specimens. 3.3 Coated metal fittings Metal fittings, such as pipe brackets, shall meet the material and corrosion requirements of BS EN 1462:1997, clauses 4 and 5. 3.4 Elastomeric sealing rings If elastomeric sealing rings are used in joints they sh

NOTE Cements conforming to BS 6209 are preferred. 4 Appearance 4.1 Internal and external surfaces The internal and external surfaces of pi
29、pes and fittings shall be smooth, clean and free from grooving and blistering, except for surfaces deliberately roughened for jointing to other materials. 4.2 Colour The pipes and fittings shall be coloured throughout the wall. NOTE The recommended colour of pipes and fittings is grey. 5 Dimensions

All threaded components shall have a thread form conforming to BS 21 or BS
33、2779 and shall have a length of engagement of not less than four full threads. If a connection is to be made to a metal threaded component, the thread form shall comply with BS 21 or BS 2779, as applicable, and shall have a length of engagement of not less than four full threads. If it is necessary
34、to have a recess in the mating end of a threaded adaptor to accommodate the fitting to which it is being connected, the recess shall not extend under the threaded portion by more than 7 mm and the minimum wall thickness given in Table 3 shall not apply at the recess. NOTE Attention is drawn to BS EN

Dimensions A, B and C shall conform
42、to Table 3. Some designs of sockets incorporate elastomeric ring seal zones longer than those illustrated and if they also include integral sealing membranes, the dimension C shall not apply, provided that the initial sealing action is achieved upon insertion of the pipe or spigot to a depth not gre
43、ater than the maximum value of C and that it is possible for the pipe or spigot to be further inserted to a depth at least equivalent to the maximum value of A. The dimensions of snap caps shall conform to the values given in Table 3 except for dimension B and dimension e 3related to B in Figure 2.
