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).

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 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 3, Plastics pipes and fittings for industrial applications. This second edition cancels and replaces the first edition (IS0/TR 10358:1993), which has been technically revised. The main changes compared to the previous edition are as follows: Due to the rare use of PE-LD inside industrial applications and the comparability of its chemical behaviour to PE-HD, the reference to PE only has been indicated. Considering the ever more frequent use in industrial fields, the following materials have been introduced: ECTFE PA-U PFA 一 PPS PSU PTFE @ IS0 2021 - All rights reserved IS0/TR 10358:2021(E) Due to the different behaviours of the materials considered in this document, they have been gathered in two separate
