DD CEN/TS 13476-4:2008 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). Guidance for the assessment of conformity
DD CEN/TS 13476-4 is a technical specification which gives guidance for the assessment of conformity to be included in the manufacturer's quality plan as part of the quality system.
DD CEN/TS 13476-4 provides:
a) Requirements for materials, components and joints given in EN 13476-1, EN 13476-2 and EN 13476-3;
b) Requirements for the manufacturer's quality;
c) Definitions and procedures to be applied if third party certification is involved.
DD CEN/TS 13476-4 is applicable to:
• Structured-wall pipes and fittings, which are intended to be used buried in ground outside the building structure only; reflected in the marking of products by “U”;
• Structured-wall pipes and fittings, which are intended to be used buried in ground both outside and within the building structure reflected in the marking of products by “UD”.
In conjunction with EN 13476-2 and EN 13476-3 it applies to structured-wall pipes and fittings with or without an integral socket with elastomeric ring seal joints as well as welded and fused joints.
