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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.
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

This document 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.
This second edition cancels and replaces the first edition (ISO 9854-2:1994), which has been technically
revised.
The main changes are as follows:
— the title has been revised;
— throughout the document, unplasticized poly(vinyl chloride), for extrusion, impact modified (PVC-U,
EP) has been replaced by high-impact poly(vinyl chloride) (PVC-HI);
— throughout the document, polypropylene (PP) and propylene-copolymer have been replaced by
propylene homopolymer (PP-H), propylene impact polymer (PP-B) and propylene random copolymer
(PP-R);
— propylene random copolymer with modified crystallinity (PP-RCT), oriented unplasticized
poly(vinyl chloride) (PVC-O), and polyethylene (PE) have been added in the Scope;
— the normative references listed in Clause 2 have been updated;
— Clause 3, Terms and definitions, has been added;
— the title of Table 1, PVC-U and PVC-U, EP pipes, has been replaced by PVC-U, PVC-HI and PVC-O pipes;
— PVC-O has been added in Table 1;
