Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to

the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

www.iso.org/iso/foreword.html.

This document was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for

the transport of fluids, Subcommittee SC 1, Plastics pipes and fittings for soil, waste and drainage (including

land drainage).

This second edition cancels and replaces the first edition (ISO 13267:2010), which has been technically

revised.
The main changes are as follows:
— normative references have been updated;
— definitions have been removed;
— technical changes have been made in 8.1, including new figures;
— minor editorial changes have been made.

Any feedback or questions on this document should be directed to the user’s national standards body. A

4 Principle

A sealed test assembly, comprising an inspection chamber or manhole base with a minimum height of

300 mm above the top of the main channel, is placed free standing, or buried in a test box on a 100 mm

sand or granular bed and covered with granular backfill to a level of minimum 300 mm above the top of

the outlets and inlets of the main channel(s). In some cases, the first section of the riser may be required

in order to achieve the minimum height of 300 mm.

The assembly is then subjected to a constant internal negative pressure, specified by the product or

system standard, for a specified time at a temperature of between 15 °C and 25 °C or as otherwise

specified in the product standard.

Alternatively, the pressure difference can be achieved by exposing the test assembly to a constant

positive external hydrostatic pressure of the same numeric value as that specified by the product or

system standard. The assembly is submerged under water in a closed tank for a specified time at a

temperature of between 15 °C and 25 °C or as otherwise specified in the product standard.

During the test, the assembly may be monitored by measuring increasing deflections with time as

defined in the product standard.

At the end of the test, the chamber base/manhole is visually checked for cracking or other defects likely

to impair the performance of the inspection chamber or manhole.

5 Apparatus

5.1 Test box, large enough to accommodate the test assembly, including the first 300 mm of riser

shaft above the top of the outlet and inlets of the main channel, such that at each side there is a free

space of 300 mm minimum between the test assembly and the side/top of the test box.

5.2 Backfill material, to cover the test assembly in the box, conforming to CEN/TS 1046:2021,

Annex A. Backfill material shall be in accordance with the minimum specification of the manufacturer.

5.3 Sealable water tank or pressure vessel, with internal dimensions capable of accommodating

the test assembly to ensure all-round clearance and a lockable lid allowing access to the open top of the
