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.
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 2286-2 was prepared by Technical Committee
ISO/TC 45, Rubber and rubber products.
Together with the other parts (see below), it cancels and replaces
ISO 2286:1986, which has been technically revised.
ISO 2286 consists of the following parts, under the general title Rubber-
and plastics-coated fabrics — Determination of roll characteristics:
— Part 1: Methods for determination of length, width and net mass
— Part 2: Methods for determination of total mass per unit area, mass per
unit area of coating and mass per unit area of substrate
— Part 3: Method for determination of thickness
Annex A forms an integral part of this part of ISO 2286.

Introduction
The total mass per unit area of a material, the mass per unit area of the
substrate cloth and the mass per unit area of the coating are quantities
which define the basic quality of a coated fabric and determine many of its
physical properties. The substrate cloth mass determined by these
methods does not necessarily represent the mass of the substrate cloth in
the uncoated state. For example, in the case of coated fabrics in which a
bonding agent has been used, the substrate cloth mass determined may
be substantially higher than the uncoated mass because the prescribed
treatment has not removed the entire coating. This will be particularly so in
cases where the substrate cloth is made from multifilament or spun-fibre
yarns. Dimensional changes in the substrate cloth during processing may
also occur.

Methods for determination of total mass per unit area, mass per unit

WARNING – Persons using this part of ISO 2286 should be familiar with normal laboratory practice. This part
of ISO 2286 does not purport to address all of the safety problems, if any, associated with its use. It is the
responsibility of the user to establish appropriate safety and health practices and to ensure compliance with
any national regulatory conditions.
1 Scope
This part of ISO 2286 describes methods of determining the total mass per unit area, the mass per unit area of the
coating and the mass per unit area of the substrate cloth of a rubber- or plastics-coated fabric. Methods for
removing coatings of specific compositions are described in annex A.
2 Normative reference
The following standard contains provisions which, through reference in this text, constitute provisions of this part of
ISO 2286. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties
to agreements based on this part of ISO 2286 are encouraged to investigate the possibility of applying the most
recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid
International Standards.
ISO 2231:1989, Rubber- or plastics-coated fabrics – Standard atmospheres for conditioning and testing.
3 Method A: Determination of total mass per unit area
3.1 Apparatus
3.1.1 Balance, accurate to ±2 mg, with a capacity such that readings remain within 10 % to 90 % of maximum
when the balance is used for this method.
3.1.2 Means of maintaining an atmosphere with a relative humidity not greater than 10 % and a temperature of
65 °C ± 5 °C.
NOTE –  Air at 20 °C and 65 % relative humidity, when heated at constant pressure to 65 °C ± 5 °C, will have a relative
humidity of approximately 5 %. Higher temperatures can lead to changes in some coatings.
2 2
3.1.3 Cutter, capable of cutting, from the sample of coated fabric, a test piece of area 100 cm ± 1 cm .
NOTE –  It has been found convenient to use a circular cutter for this purpose, but square or rectangular test pieces may be
used provided they are within the accuracy specified above.

3.2 Preparation of test pieces
Using the cutter (3.1.3) cut five test pieces from the sample, from positions spaced reasonably evenly and close to
the diagonal across the width of the sample so that the full width of the coated fabric is represented.
Do not take any test pieces within 1 m of a production-manufactured roll end.
3.3 Procedure
Dry the test pieces to constant mass in an atmosphere with a relative humidity not higher than 10 % at a
temperature of 65 °C ± 5 °C.
Condition the test pieces in accordance with ISO 2231 and, without removing them from the conditioning
atmosphere, determine the mass of each to the nearest 5 mg and the surface area of each to within 1 %.
NOTE –  Any estimate of the mass per unit area of the coated fabric derived from the total net mass of the roll and its known
length and width may be inaccurate because a complete roll of coated fabric cannot normally be conditioned to equilibrium in a
standard atmosphere. Such inaccuracies are due to excesses or de
