It provides a practical guide to the design, installation and operation of unplasticised polyvinyl chloride (PVC) pipelines used for the conveyance of foul water.  \nIts revision has been prompted by the amalgamation of the New Zealand and Australian Standards, which has resulted in two key documents; AS/NZS 1260 PVC pipes and fittings fordrain waste and vent, AS/NZS 3500.2.2 Sanitary plumbing and drainage-acceptable solutions Installation method.  \nSince the introduction of PVC Pipes into the New Zealand plumbing and drainage market over three decades ago, PVC DWV pipe has become an integral link in foul water drainage systems in this country.  \nPVC pipe has proven to be the most competitive in cost, with ease of installation combined with its physical characteristics of corrosion resistance and high strength to weight ratio, justifying its selection as the prime material option for drainage networks.  \nOver the last fifteen years extensive research and development has resulted in continual improvements in processing techniques, quality control and behavioural understanding of the material. Users of PVC pipes and fittings manufactured to AS/NZS 1260 are assured of consistently high quality products which, in addition to their traditional characteristics, now have enhanced toughness.  \nThis second edition reflects the changes in specifications and materials which have taken place since the first edition was produced.  \nWe trust you will find this design manual informative and a key point of reference in conducting any aspect of design, installation or sale.  \n D W V T E C H N I C A L D E S I G N M A N U A L  \nINTRODUCTION  \nSECTION 1 : P V C P IPE PROPERTIES  \n1.
