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 9852 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 9852:1995), which has been revised to align it
with EN 580:2003.
The principal modifications are the following:
⎯ the wall thickness ranges “8 u e u 16” and “e > 16” in Table 1 have been changed to “8 u e < 16” and
“16 u e”, respectively, to align them with those in EN 580:2003;
⎯ the surface of the dichloromethane layer has been reduced to the minimum and the thickness of the
water layer covering the dichloromethane increased (see 6.2);
⎯ after immersion in the dichloromethane, the test piece is held in the water layer to allow it to “drip” before
final drying and inspection (see 7.4);
⎯ in the event of the pipe being attacked (see 8.2), giving a description of the attack has become optional,
dealt with in a new Annex A (informative).
⎯ the lower limit for the test temperature (12 °C) has been moved to 6.3, and Annex A, “Basic specification”,
has been deleted;
⎯ a typical test arrangement, with the deeper water layer (acting both as a block to evaporation and as a
“drip” zone), is
