Over deze norm
This European Standard specifies the definitions and requirements for ancillary fittings of unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), and polyethylene (PE) intended to be used in non-pressure underground drainage and sewerage systems, conforming to EN 476: a) outside the building structure (application area code “U”), reflected in the marking of products by “U”, and b) both buried in ground within the building structure (application area code “D”) and outside the building structure (application area code “U”), reflected in the marking of products by “UD”. It also specifies the test parameters for the test methods referred in this standard. The ancillary fittings covered by this standard are the following: - sealed access fittings; - rodding point covers; - rodding tees; - mechanical saddles; - inspection chambers for shallow non-roadway applications to a maximum depth of 1,25 m. The fittings can be manufactured by various methods e.g. injection moulding, rotational moulding, spiral winding or fabricated from components made to other standards. The jointing can be with: - elastomeric ring seal joint; - cemented joint for PVC-U; - welded joint for PP and PE.
