Plastics piping systems for non-pressure underground drainage and sewerage - Unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) - Part 2: Specifications for manholes and inspection chambers

This document specifies the definitions and requirements for unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) manholes and inspection chambers intended for non-pressure underground drainage and sewerage systems up to a maximum depth of 6 m from ground level to the invert of the manhole or inspection chamber. This document covers manholes and inspection chambers, with bases having a flow channel, and their joints to the piping system. Manholes and inspection chambers are intended to be used in pedestrian or vehicular traffic areas outside the building structure. NOTE 1 The intended use in underground installation outside the building structure is reflected in the marking of products by the application area code "U". NOTE 2 Products complying with this document can also be used in non-traffic areas. NOTE 3 Products complying with this standard can be installed in underground applications without additional static calculation. NOTE 4 Shallow chambers are specified in EN 13598-1 [1]. Manholes and inspection chambers complying with EN 13598-2 are made from a prescribed set of components that are manufactured from unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE) and assembled together. NOTE 5 The complete manhole or inspection chamber assembly can also include items which are not covered by this document (for example near surface or surface components). NOTE 6 Manholes and inspection chambers can be supplied with covers, frame covers and gratings complying with the relevant part of EN 124 [2]. Manholes and inspection chambers complying with EN 13598-2 may be used for storm-water systems. Manhole and inspection chamber components can be manufactured by various methods e.g. extrusion, injection moulding, rotational moulding, low-pressure moulding or fabricated. NOTE 7 Manholes and inspection chambers can be site assembled from different components, but can also be manufactured as a single unit. NOTE 8 Manholes and inspection chambers can be subject to national regulations and / or local provisions.
