Rubber- or plastics-coated fabrics -- Low-temperature bend test

ISO 4675:2017 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 relationship between this test and service performance can be given or implied.

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.

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.
