European foreword
This document (prEN 17152-1:2025) 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 supersedes EN 17152-1:2019+AC:2020.
The main changes with respect to EN 17152-1:2019+AC:2020 are listed below:
— Table A.1 added minimum number of test specimen;
— Table 2 new optional tests added;
— Clause 3 new definitions added (e.g. reference value and declared value);
— reference to new improved prEN 17151-1;
— subclause 10.2 improved with more information;
— editorial improvements through the document.
This standard is supported by separate standards on test methods to which normative references are
made.
EN 17152-series consists of the following parts under the general title Plastics piping systems for non-
pressure underground conveyance and storage of surface water - Boxes used for infiltration, attenuation
and storage systems:
— Part 1: Specifications for boxes made of PP and PVC-U [this document];
— Part 3: Assessment of conformity (CEN/TS);
— Part 4: Guidance for structural design of modular systems (CEN/TS).
Recommended practices for installation are described in CEN/TR 17179 [1].
These products are always used in a modular system consisting of multiple boxes.
National standards for pipes and fittings for the transport of surface water are not considered to be
conflicting with this standard and can thus be allowed to coexist.

Introduction
The products covered by this document are part of surface water management system.
This document is intended to reflect the current state of knowledge of determining and predicting the
long-term lifetime of product groups mentioned in the scope while maintaining reasonable testing times
for producers and developers of these systems.

1 Scope
This document gives the definitions and specifies the minimum requirements for injection moulded,
extruded and thermoformed thermoplastics cuboid shaped boxes, including integral components, used
in underground systems for infiltration, attenuation and storage of surface water (e.g. storm water) and
manufactured from polypropylene (PP) or unplasticized polyvinylchloride (PVC-U).
Product properties are determined by a combination of material specifications, design and
manufacturing process.
These boxes are intended for buried underground use, e.g. in landscape, pedestrian or vehicular traffic
areas.
A box can either be factory assembled, or site assembled from different components.
These boxes are intended to be used as elements in a modular system where the manufacturer states in
the documentation how the components are assembled to create a complete infiltration, attenuation or
storage system.
NOTE Non load bearing component(s) can be manufactured by various methods e.g. extrusion, injection
moulding, rotational moulding, thermoforming and low-pressure injection moulding.
