Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
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. IS0
collaborates closely with the International Electrotechnical Commission
(I EC) 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 IS0 527-2 was prepared by Technical Committee
lSO/TC 61, Plastics, Sub-Committee SC 2, Mechanical properties.
Together with the other parts of IS0 527, it cancels and replaces IS0
Recommendation R 527:1966, which has been technically revised.
Annex A of this part of IS0 527 cancels and replaces IS0 6239:1986,
P/as tics - Determination of tensile properties by use of small
specimens.
IS0 527 consists of the following parts, under the general title
P/as tics - Determination of tensile properties:
- Part I: General principles
- Part 2: Test conditions for moulding and extrusion plastics
- Part 3: Test conditions for sheet and film
- Part 4: Test conditions for isotropic and orthotropic fibre-reinforced
p/as tic composites
- Part 5: Test conditions for unidirectional fibre-reinforced plastic
composites
Annex A forms an integral part of this part of IS0 527.
