Part 2: Specifications for manholes and
inspection chambers in traffic areas
and dee
This European Standard specifies the definitions and requirements for buried manholes and
inspection chambers 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 modifier (PP-MD) or polyethylene (PE). These products are intended for
use in pedestrian or vehicular 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”. Such products are also deemed to meet the
requirements of EN 13598-1 for application area U without the need for further testing. If additionally
marked application area D then these products must additionally be tested to show compliance to the
elevated temperature cycling requirement of Clause 10 of EN 13598-1.
This European 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 European 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 / 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 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.
NOTE Both manholes and inspection chambers can be site assembled from different components, but can
also be manufactured as a single unit. In either case, the following functional parts can be recognized:
a) base (always present)
In case of a one-piece chamber or manhole, the base part ends at a distance of 300 mm
measured from the top of the main channel;
b) riser (depth dependent);
c) telescopic part (design dependent);
d) cone (dependent on the design of near surface components and their recommended installation);
e) other near surface components
