Plastics piping systems for non-pressure underground drainage and sewerage - Structured-wall piping systems of unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) - Part 2: Specifications for pipes and fittings with smooth
This part of EN 13476, together with EN 13476-1, specifies the definitions and requirements for pipes, fittings and the system based on unplasticized poly(vinyl chloride) (PVC-U), polypropylene(PP) and polyethylene(PE) structured-wall piping system that are intended to be used for non-pressure underground drainage and sewerage systems.
This part is applicable to pipes and fittings with smooth internal and external surfaces, designated as Type A.
It specifies test methods and test parameters as well as requirements.
This part is applicalbe to:
a) strutured-wall pipes and fittings, which are intended to be used buried underground outside the building structure;reflected in the marking of products by"U";
b) structured-wall pipes and fittings, which are intended to be used buried underground both outside(application area code"U") and within a building structure(application area code"D"); reflected in the marking of products by"UD".
This part is applicable to structured-wall pipes and fittings with or without an integral socket with elastomeric ring seal joints as well as welded and fused joints.
This part covers a range of pipe and fitting sizes, materials, pipe constructions, stiffness classes, application classes, and tolerance classes and gives recommendations concerning colours.
NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.
NOTE 2 For dimension larger than DN 1200 OD/ID this document may be applied regarding appearance, colour, physical and mechanical characteristics as well as performance requirements.
