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, govern-
mental 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 approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 2231 was prepared by Technical Committee ISO/TC 45,
Rubber and rubber products.
This second edition cancels and replaces the first edition (ISO 2231 : 19731, clauses 3
and 4 of which have been technically revised (see clauses 5 and 6 in revised text). In ad-
dition, a new clause on pre-conditioning has been introduced (clause 4 in revised text).

Introduction
Most coated fabrics contain a certain amount of moisture absorbed from the air with
which they are in contact, and the amount of moisture depends on the quantity of
water vapour in the air.
Certain properties, particularly mass and those concerned with the breaking of
threads, are affected by the moisture content of the fabric. In Order to standardize
methods of test it is, therefore, important to control the moisture content of the mate-
rial under test. This is done by conditioning test pieces in an atmosphere of controlled
humidity before testing. For some other properties, the effect of the moisture content
of the fabric is minimal, and it is only necessary to condition for temperature.
