The material from which the pipes and fittings are produced shall consist of polyvinyl chloride (PVC) together with additives necessary for the manufacture and performance requirements of this Standard. Such additives shall include a minimum of 1.5 parts of rutile titanium dioxide (TiO2) per 100 parts per mass of PVC. This requirement does not apply to fittings greater than DN 150 with non-interference fit parallel sockets. The PVC content of the pipe or fitting shall be not less than 83.3%. Establishment of the TiO2 and PVC content shall be achieved by the use of process control methods. Rework material of the same composition, regenerated from the manufacturer’s own production of pipes and fittings made to this Standard may be used. Additives containing compounds based on lead (Pb),cadmium (Cd) or mercury (Hg) shall not be used.Pipe and fitting ends shall not have any chips and rough edges. Jointing surfaces shall be smooth. The axis of sockets formed on the ends of pipes and fitings shall be parallel within 2° to the axis of the fitting.
The jointing surfaces of sockets on pipes and fittings for solvent cement jointing shall taper uniformly from the mouth to the root of the socket.
NOTE: The defects described in Clauses 2.5.1 and 2.5.3 cannot be completely quantified. Where the presence, size or frequency of any such defects are considered to be of concern, arrangements for acceptable product quality should be made by agreements between relevant parties to confirm acceptance of the product. This may be achieved by the provision of acceptable type samples.Where defects are prescnt and the product is submitted for acceptance, the manufacturer should be able to demonstrate fitness for purpose.
This Section specifies the minimum performance requirements applicable to PVC pressure pipes and fittings at the time of manufacture.
NOTE: Test requirements given in this Section relate to product performance only and are not intended to relate to field performance.AS NZS 1477 pdf free download.
