Upper and Vamp Material Cold Flexing Tester GT-KC04B
|
Application: This Upper and Vamp Material Cold Flexing Tester is used to determine the propensity for materials to crack or otherwise fail at flexing creases, but can also be used to assess whether leathers are likely to produce salt spue. In particular the test simulates conditions in the vamp part of footwear during walking. The test can be conducted with either wet or dry specimens at room temperature or with dry specimens at sub zero temperatures. The method is applicable to all flexible materials and in particular those used to manufacture outers and linings of footwear uppers such as leathers, coated fabrics and textiles
Standards:
ISO 5423 section 5.2, EN ISO 20344 Section 6.5, ISO 4643 (Annex B), AS/NZS 2210.2 Section 6.5.2 |
Its principle: A square specimen of the material is folded over two inverted V-shaped clamps. The
clamps are able to move relative to one another so that as they become closer the specimen is
flexed to produce one downward crease surrounded by four upward creases. During the test the
clamps oscillate at a constant speed so that the specimen is repeatedly flexed. After a
predetermined number of cycles the test is stopped and the specimen is visually examined for
signs of damage or salt spue.
