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 on 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 the following
URL: 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 13257:2010), which has been technically
revised. The major modifications to the previous edition are:
— revision of the Scope to delete the references to application areas "B", "BD" and "UD";
— addition in the Scope of the range of nominal outside diameters of components to which this method
is applicable;
— addition of a definition for “sagging”;
— complete review of Clause 6, Test assemblies, in particular distinction between test assemblies
including pipes with integral sockets and fittings with socket and spigot (Figure 1) and test
assemblies including pipes without integral socket and fittings with sockets (Figure 2) for
components d ≥ 40 mm;
n
— in Clause 7, addition of Figure 4 to illustrate the measuring point of the column of water.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.

INTERNATIONAL STANDARD ISO 13257:2018(E)
Thermoplastics piping systems for non-pressure
applications — Test method for resistance to elevated
temperature cycling
1 Scope
This document specifies a test method for determining the resistance to elevated temperature cycling
of thermoplastics piping systems for non-pressure applications, inside buildings or buried in the ground
within the building structure.
This document is applicable to piping systems with components of nominal outside diameters up to and
including 200 mm.
Although limited to nominal outside diameters up to and including 200 mm, the test results may be
extrapolated to products of larger nominal outside diameters from the same range.
