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.
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
different types of ISO documents should be noted. This document was drafted 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 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. Details of
any patent rights identified during the development of 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 information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity 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

This document was prepared by Technical Committee ISO/TC 45, Rubber and rubber products,
Subcommittee SC 4, Products (other than hoses).
This third edition cancels and replaces the second edition (ISO 4675:1990), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— a WARNING has been inserted before the scope;
— Clause 3 has been added;
— in Figure 2, the dimension of H has been corrected.

Rubber- or plastics-coated fabrics — Low-temperature
bend test
WARNING — Persons using this document should be familiar with normal laboratory practice.
This document 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 document specifies a method for determining the ability of fabrics coated with rubber or plastics to
resist the effect of low temperature when subjected to bending at specified temperatures after definite
periods of exposure. This method is applicable to material with a thickness within the range 0,1 mm to
2,2 mm. For materials of greater thickness than this, modifications to the standard equipment apply
(see 9.2, third paragraph).
Because fabrics coated with rubber or plastics are used in different applications requiring low
temperature flexing, no general relationsh
