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 22088-6 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 6, Ageing,
chemical and environmental resistance.
ISO 22088 consists of the following parts, under the general title Plastics — Determination of resistance to
environmental stress cracking (ESC):
⎯ Part 1: General guidance
⎯ Part 2: Constant tensile load method (replacement of ISO 6252:1992)
⎯ Part 3: Bent strip method (replacement of ISO 4599:1986)
⎯ Part 4: Ball or pin impression method (replacement of ISO 4600:1992)
⎯ Part 5: Constant tensile deformation method (new test method)
⎯ Part 6: Slow strain rate method (new test method)

INTERNATIONAL STANDARD ISO 22088-6:2006(E)
Plastics — Determination of resistance to environmental stress
cracking (ESC) —
Part 6:
Slow strain rate method
1 Scope
This part of ISO 22088 describes a procedure for assessing the environmental stress cracking (ESC)
susceptibility of polymeric materials in chemical environments by slowly increasing the strain applied to a
tensile specimen at a constant rate.
It is applicable to test specimens prepared by moulding and/or machining and can be used to assess the
relative ESC susceptibility of a material exposed to different environments or the relative ESC susceptibility of
different plastics exposed to a specific environment.
This is essentially a ranking test and is not intended for the provision of design data.
The principle advantage of the test compared with the test methods described in Parts 2 to 5 of ISO 22088 is
the rapidity with which the ESC susceptibility of a particular polymer/environment combination can be
assessed.
