European foreword
This document (prEN 13598-2:2025) has been prepared by Technical Committee CEN/TC 155
“Plastics piping systems and ducting systems”, the secretariat of which is held by NEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13598-2:2020.
EN 13598-2:2020:
1) the terminology has been updated to align with the TC155 Oslo agreement and EN 14541-1.
Additional terms and definitions have also been included.
2) material clauses and Annex D have been updated;
3) the format of units and symbols in tables has been updated.
EN 13598 consists of the following parts under the general title Plastics piping systems for non-
pressure underground drains and sewers — Unplasticized polyvinyl chloride (PVC-U),
polypropylene (PP) and polyethylene (PE):
— Part 1: Specification for ancillary fittings and shallow chambers (under revision);
— Part 2: Specifications for manholes and inspection chambers (this document);
— Part 3: Assessment of conformity (CEN/TS under revision).
1 Scope
This document is part of a System Standard for plastics piping systems of a particular material for
a specified application.
System Standards are based on the results of the work being undertaken in ISO/TC 138 “Plastics
pipes, fittings and valves for the transport of fluids”, which is a Technical Committee of the
International Organization for Standardization (ISO).
They are supported by separate standards on test methods to which references are made
throughout the System Standard.
The System Standards are consistent with general standards on functional requirements and on
recommended practice for installation.
This document does not cover sewage pump chambers, valve chambers and similar products.
This document specifies the definitions and requirements for unplasticized polyvinyl chloride
(PVC-U), polypropylene (PP) and polyethylene (PE) manholes and inspection chambers having a
base with a flow channel and their joints to the piping system, intended for use in non-pressure
underground drains and sewers for wastewater, up to a maximum depth of 6 m from ground level
to the invert of the flow channel.
This document is applicable to manholes and inspection chambers, intended for use buried in the
ground outside a building structure only; reflected by the marking of products by “U”.
This document is applicable to manholes and inspection chambers intended for use in pedestrian
or vehicular trafficked areas.
NOTE 2 Products complying with this document can also be used in non-traffic areas.
NOTE 3 Products complying with this document can be installed in underground applications without
additional static calculation.
Manhole and inspection chamber components can be manufactured by various methods e.g.
extrusion, injection moulding, rotational moulding, low-pressure moulding or factory fabricated.
Manholes and inspection chambers complying with EN 13598-2 are made from a prescribed set
of components that are assembled together or manufactured as a single unit.
NOTE 4 The complete manhole or inspection chamber assembly also includes items which are not
specified in this document (for example near surface or surface components such as covers, frames and
gratings complying with the relevant part of EN 124[1]).
NOTE 5 Manholes and inspection chambers can be subject to national regulations and / or local
provisions.

polypropylene (PP) or polyethylene (PE).
The use of material, that has been classified as re-worked material in this document or in other
standards according to Table 2, originating from the same compound/formulation, is permitted
without additional requirements.
NOTE 1 If a component comprises of sub-components of mixed materials (e.g PP and PVC-U) or the sub-
components are generated using different processes, care is to be taken to ensure separation prior to use
as reworked material.
NOTE 2 Reworked material generated from fittings complying with e.g. EN 1401-1 can be used, if the
same formulation is used for the production of components complying with this document.
The use of recyclates is permitted, provided they comply with Annex D.
Recyclates can also be added to virgin or to reworked material or a mixture of these materials.
The durability is tested according to 5.2 to 5.5 on the relevant components.
NOTE 3 Attention is drawn to changing of European and/or national regulations regarding e.g. heavy
metals.

5.6 Sealing ring retaining components
It is permitted that sealing rings are retained using means made from polymers other than
PVC-U, PP or PE.
6 General characteristics
6.1 Appearance
When viewed without magnification, the internal and external surfaces of manholes and
inspection chambers shall be smooth, clean and free from defects likely to prevent conformity
with this document.
Pipe ends or spigots shall be cleanly cut and square with their axis.
6.2 Colour
Any colour may be used.
7 Geometrical characteristics
7.1 General
The manufacturer shall specify the relevant geometrical characteristics and the tolerances.
All dimensions shall be measured in accordance with EN ISO 3126.
7.2 Dimensions of manholes and inspection chambers
7.2.1 Manholes
The diameter of the riser shall be used to designate the nominal size of manholes.
In the absence of national regulations the diameter of the clear opening of the manhole cover
according to EN 124 (all parts) shall be ≥ 600 mm.
For a manhole with circular section, the nominal inside diameter of the riser shall be ≥ 1 000 mm
(see Figure 1).
NOTE National or local safety - regulations or the relevant authority can specify larger minimum
dimensions e.g. for the access.
In specific circumstances, where national regulations allow, manholes may have smaller
dimensions. In this case for a manhole with circular section, the nominal inside diameter of the
riser shall be ≥ 800 mm.
For this type of manhole special entry equipment (e.g. harness and winch) is required.
7.2.2 Inspection chambers
The diameter of the riser shall be used to designate the nominal size of inspection chambers.
For an inspection chamber with circular section, the nominal inside diameter of the riser shall
be ≥ 200 mm (see Figure 2).
7.3 Dimensions of base connections to pipework
The wall thickness of the spigot/socket for pipe connections shall not be less than those specified
either in EN 1401-1 or EN 13476 (all parts).
Socket (d ) and spigot (d ) diameters, length of engagement (A), length of spigots (L ) and their
sm em 1
tolerances shall enable compatibility to pipe work in accordance with the product standards of
the pipes that they are intended to be connected to.
NOTE The requirement for wall thickness of the spigot/socket for pipe connections is not applicable
for riser to base assembly or sockets or spigots of risers, cones or telescopic adaptors.
When tested in the factory, joints for base connections to pipework shall have a continuity of
invert within the following calculated maximum tolerances:
— ≤ DN/OD 315 or DN/ID 300: maximum step 6 mm;
— > DN/OD 315 or DN/ID 300: maximum step 0,02 mm × DN limited to 30 mm.
7.4 Geometrical characteristics of steps and ladders
7.4.1 General
Manholes can be provided with man entry equipment such as:
— steps;
— permanently fixed ladders (can be fitted either before or after installation);
— fixing provisions for ladders.
7.4.2 Steps
Plastics steps shall comply with the following requirements:
— these steps shall have a minimum width of step profile of 20 mm;
— these steps shall have a minimum width for single steps of 145 mm or for double steps a
minimum width of 250 mm;
— these steps shall have a minimum projection of 120 mm from the internal wall of the riser
(see Figure 3c);
— the vertical spacing within a finished structure shall relate to the internal height of the
manholes and shall be within the range 250 mm to 350 mm (see Figure 3c);
— single steps shall be fixed, with a tolerance of ± 10 mm, alternatively at centres in vertical
plan within the range 270 mm and 300 mm (see Figure 3b);
— double steps shall be fixed vertically above each other (see Figure 3a).
Steps that are totally or partly manufactured from cast iron, steel or aluminium shall comply with
EN 13101.

7.4.3 Permanently fixed ladders
When a manhole includes a fixed ladder, the ladder including fixing provisions shall conform to
the requirements of EN 14396.
7.4.4 Fixing provisions for ladders
When a manhole is supplied with fixing provisions for a ladder, these shall conform to the
relevant requirements of EN 14396.
8 Mechanical characteristics
When tested as detailed in Tables 6, 7 and 8, as applicable, the manhole or inspection chamber
shall conform to the corresponding requirements.
