This European Standard was approved by CEN on 19 September 2017.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by
translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

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. Esch 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.
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.
International Standard ISO 2507-1 was prepared by Technical Committee
lSO/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 specifi-
ca tions.
This first edition of ISO 2507-1, and ISO 2507-2, cancels and replaces the
second edition of ISO 2507 (ISO 25073 982) of which it constitutes a
technical revision.
ISO 2507 consists of the following Parts, under the general title Thermo-
plastics pipes and fittings - Vita t softening tempera tut-e:
- Part 7: General test method
- Part 2: Test conditions for unplasticized poly(vinyl chloride) (PVC-U)
or chlorinated poly(vinyl chloride) (PVC-C) pipes and fittings and for
high impact resistance poly(vin yl chloride) (PVC-Hl) pipes
- Part 3: Test conditions for acryionitrile/butadiene/styrene (ABS) and
acrylonitrile/styrene/acrylic ester (ASA) pipes and fittings

Introduction
This International Standard is based on ISO 306.
For convenience of use, it has been considered preferable to draw up a
complete document for use in determining the Vicat softening tempera-
ture of thermoplastics pipes and fittings. For further details, reference to
ISO 306 is recommended.
Please note, however, that ISO 306 is applicable to materials in the form
of sheets, whereas this International Standard is applicable to materials in
the form of pipes and fittings.
ISO 2507 comprises three Parts: the first gives the general conditions
under which the Vicat softening temperature of a pipe or fitting is deter-
mined, the other two Parts provide the particular requirements for con-
ducting tests on pipes and fittings of different materials (see the
Foreword).
The basic specifications for various materials are given in the informative
annexes of the appropriate Parts.
