Plastics piping systems for non-pressure underground drainage and sewerage — Unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifiers (PP-MD) and polyethylene (PE) — Specifications for manholes and inspecti

Abstract

This International Standard specifies the definitions and requirements for buried manholes and inspection
chambers (circular or non-circular) installed to a maximum depth of 6 m from ground level to the invert of the
main chamber and manufactured from unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP),
polypropylene with mineral modifiers (PP-MD) or polyethylene (PE). These products are intended for use in
traffic areas and underground installations conforming to the general requirements given in EN 476 and are
used outside the building structure (application area code “U”). They are therefore marked accordingly with a
“U”.
This International Standard is only applicable to those chamber/manhole items where the manufacturer has
clearly stated in the documentation how the components shall be assembled to create a complete manhole or
inspection chamber.
The inspection chambers covered by this International Standard comprise the following:
? inspection chambers providing access to the drainage or sewerage system by means of inspection and
cleaning equipment;
? chambers designated as manholes providing man access to the drainage or sewerage system.
The inspection chamber or manhole can be manufactured by various methods, e.g. injection moulding,
rotational moulding, low-pressure moulding or fabricated from components made in accordance with other
International Standards.
The jointing of components can be achieved using:
? elastomeric ring seal joints;
? adhesive joints for PVC-U;
? welded joints for PVC-U, PP and PE;
? extrusion welding;
? mechanical jointing.
