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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 19893 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the
transport of fluids, Subcommittee SC 5, General properties of pipes, fittings and valves of plastic materials and
their accessories — Test methods and basic specifications.
INTERNATIONAL STANDARD ISO 19893:2011(E)

Plastics piping systems — Thermoplastics pipes and fittings for
hot and cold water — Test method for the resistance of
mounted assemblies to temperature cycling
1 Scope
This International Standard specifies a method for testing the resistance to temperature cycling of joints for
piping systems with rigid or flexible thermoplastics pipes.
It is applicable to thermoplastics piping systems intended to be used in hot and cold water pressure
applications.
2 Principle
A test assembly of pipes and fittings (see Figure 1) is subjected to temperature cycling by the passage of
water under pressure using hot and cold water alternately, for a specified number of cycles.
While being subjected to temperature cycling, parts of the assembly of pipes and fittings are maintained under
tensile stress and/or flexural strain using static clamps.
During and after the test, the assembly is monitored for signs of leakage.
NOTE It is assumed that the following test parameters are set by the reference product standard (i.e. the standard
making reference to this International Standard):
a) the test temperatures (see 3.1, 3.2 and 6.1);
b) the duration of a complete cycle and each part of the cycle (see 3.1, 3.2 and 6.1);
c) the test pressure (see 3.6 and 6.1);
d) the tensile stress (see 3.8 and 5.3);
e) the bending radius (see Clause 4 and Figures 1 and 2);
f) the total number of cycles, including the first five cycles (see 6.2 and 6.3).
