1 Scope
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 systems 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 applicable to: a) structured-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 the 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 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.
7.2 Dimensions
7.2.1 Designation
Pipes and fittings are sized either according to their outside diameter (DN/OD-series) and/or according to their inside diameter (DN/ID-series). NOTE Because of the permitted variations in geometric details, conformity to this standard does not ensure interchangeability of pipes, fittings and other components from different manufacturers and/ or different designs. Within the same class of tolerances, the Type A1 and components in accordance with EN 1401-1, EN 1852-1, EN 14758-1 or EN 12666-1 are interchangeable. EN 1852-1, EN 14758-1 and EN 12666-1 include two sets of tolerances on the outside diameters of spigots.
7.2.2 Lengths of pipe
The effective length of the pipe I shall not be less than that specified by the manufacturer when measured as shown in Figure 3.
7.2.3 Diameters ofType A pipes and Type A spigots of pipes and fittings
The outside diameters and their tolerances are specified in Table 5 and the other dimensions in Table 6. Outside diameters of Type A pipes and plain spigots for OD series pipes and fittings intended to have jointing dimensions conforming to EN 1401-1, EN 1852-1, EN 14758-1 or EN 12666-1 shall meet the values specified in Table 5. Other nominal sizes greater than DN/ID 100 and DN/OD 110 and less than DN/OD 3000 and DN/ID 3000, than given in Table 5 and Table 6 are permitted. They should preferably be selected from the Renard series R 40, ISO 3, or traditional national dimensions. In such cases, the nominal size DN/ID of pipes and fittings shall be selected in such a way that the designed minimum mean inside diameter dim,min conforms to the requirement to maximum limit deviations on internal diameters in EN 476. For DN/ODs and DN/IDs not specified in Table5 and Table 6, the dimensions shall be linearly interpolated between the adjacent values specified in the tables.
