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;
inspection chambers for shallow non-roadway applications to a maximum depth of 1,25 m.
NOTE 1 Inspection chambers as defined in 6.1.3 of EN 476:1997 have a riser with a DN/ID less than 800 mm.
NOTE 2 Deep inspection chambers and manholes for application area U are specified in Part 2 of this standard.
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.
NOTE 3 Pipes, fittings and other components conforming to any of the plastics products standards listed in Clause 2 can be
used with ancillary fittings conforming to this standard, provided they conform to the requirements for joint dimensions given in
Clause 6 and to the requirements of Table 6.
