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

5 Material
5.1 General
The material from which the components are made shall either be PB, PE, PE-RT, PE-X, or PP, as
applicable, to which are added those additives that are needed to facilitate the manufacture of pipes,
fittings, and valves conforming to this International Standard.
If additives are used, they shall be uniformly dispersed.
The additives shall not be used separately or together in quantities sufficient to impair the fabrication
or fusion characteristics of the component or to impair the chemical, physical, or mechanical
characteristics as specified in this International Standard.
5.2 Hydrostatic strength properties
The material shall be evaluated according to ISO 9080 by analysis of pressure tests carried out in
accordance with ISO 1167-1 and ISO 1167-2 to classify the material in accordance with ISO 12162.
Conformity of the relevant material to the reference curves given for PB (see Annex A), PE (see
Annex B), PE-RT (see Annex C), PE-X (see Annex D), and PP (see Annex E) shall be proven according
to the applicable Annex of this International Standard. At least 97,5 % of the data points shall be on or
above the reference curves. For design, these reference curves shall be used as a basis.
The material shall be classified by the raw material producer.
