Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work o f 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 o f
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
di fferent types o f ISO documents should be noted. This document was dra fted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some o f the elements o f this document may be the subject o f
patent rights. ISO shall not be held responsible for identi fying any or all such patent rights. Details o f
any patent rights identified during the development o f the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is in formation given for the convenience o f users and does not

constitute an endorsement.

For an explanation on the meaning o f ISO specific terms and expressions related to con formity

assessment, as well as information about ISO’s adherence to the World Trade Organization (WTO)
principles in the Technical Barriers to Trade (TBT) see the following URL: Foreword – Supplementary
information
The committee responsible for this document is ISO/TC 45, Rubber and rubber products, Subcommittee
SC 4, Products (other than hoses).

This second edition cancels and replaces the first edition (ISO 2286-3:1998), which has been technically

revised. The changes are as follows:
— in 4.1, the smallest scale reading has been changed to 0,01 mm;
— in 4.2, the pressure of 5 kPa has been added and the force corresponding to each pressure has been
added for reference;
— in Clause 5 , the conditioning atmosphere has been clarified;
— in Clause 6 , the requirement for recording the temperature and humidity has been added; the usable
width has been clearly specified; the period o f pressing time has been changed to more flexible;

— in Clause 8, items b) and e) have been added.
ISO 2286 consists of the following parts, under the general title Rubber– or plastics–coated fabrics —

period of time to get stable in the test report. Record the dial gauge reading to the nearest 0,01 mm.
If the fabric has an embossed surface, do not avoid the areas of embossing.
