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 meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
ISO 17694 was prepared by the European Committee Standardization (CEN) Technical Committee

INTERNATIONAL STANDARD ISO 17694:2016(E)
Footwear — Test methods for uppers and lining — Flex
resistance
1 Scope
This International Standard specifies a test method for determining the flex resistance of uppers and
linings irrespective of the material in order to assess the suitability for the end use.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 3696, Water for analytical laboratory use — Specification and test methods
ISO 5402-1:2011, Leather — Determination of flex resistance — Part 1: Flexometer method
1)
ISO 17709 , Footwear — Sampling location, preparation and duration of conditioning of samples and
test pieces
2)
ISO 18454 , Footwear — Standard atmospheres for conditioning and testing of footwear and components
for footwear
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
flex resistance
resistance of a material to crack or otherwise fail at flexing creases
3.2
surface
visible site of the material during the use at the shoe
Note 1 to entry: The visible site of the material can be by upper the grain site of the leather or the coated site of a
coated textile, by lining the site of the material visible from the inside of the shoe.
4 Short description
Test specimens are cut from a shoe vamp or from material for shoes, folded and inserted in the test
machine. The test simulates the damage caused by the inward folding of the vamp of the upper, but
does not readily reproduce damage occurring on outward folds. It is carried out humid, dry or in a cold
climate.
5 Apparatus and material
The following apparatus and material shall be used.
1) EN 13400 is equivalent to ISO 17709.
2) EN 12222 is equivalent to ISO 18454.
ISO 17694:2016(E)
5.1 Test machine, in accordance with ISO 5402-1:2011, 4.1 including the following.
5.1.1 At least four pairs of clamps. The upper clamp consists of a pair of flat plates as shown in
Figure 1.
The lower clamp is fixed and lies in the same vertical plane as the upper clamp.

5.1.2 Means of applying a simple harmonic reciprocating action, to repeatedly move the upper
clamp through an angle of 22°30’ ± 0°30’. The speed of oscillation shall be (100 ± 5) cycles/min.
The distance between the upper and lower clamp, when the upper clamp is in the horizontal position,
shall be (25 ± 1) mm.
5.1.3 Means of counting, the total number of cycles.
5.2 Press knife, (70 ± 1) mm × (45 ± 1) mm or similar for cutting test specimens.
5.3 Optical magnifier, with a magnification of approximately four to six times.
5.4 For wetting test specimens.
5.4.1 Glass dish, minimum of 100 mm diameter and 25 mm depth.
5.4.2 Distilled or deionised water, complying with Grade 3 of ISO 3696.
