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 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 flow profile bases, 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 may 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. 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 may also include non-plastic items (near surface or surface components for example) which are not covered by this document. NOTE 6 Manholes and inspection chambers may be supplied with covers, frame covers and gratings complying with the relevant part of EN 124 [1]. Manholes and inspection chambers complying with EN 13598-2 comply with the general requirements given in EN 476. 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.
