29、 descriptionTest 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

If required, temperatures down to -30 C can be used.6 Sampling and c
36、onditioning6.1 GeneralCut out the required number (see Table 1) of rectangular test specimens with the press knife. Cut half the required number of test specimens with the longer edge parallel with the along direction of the material backbone direction for leather and selvedge (warp) or machine dire
37、ction for non-leather materials and half perpendicular to this. For test specimens cut from uppers, the along direction is the X-axis as defined in ISO 17709.For uppers, cut a test specimen from the centre of the forepart so that the centre of the test specimen aligns with the point of most flexing
38、in the shoe.For materials, cut test specimens from a range of positions across the full usable width and length of the sheet material. For a material with a woven structure, this shall prevent any two test specimens containing the same warp or weft threads.It can be that it is impossible to cut a te
39、st specimen of sufficient size from certain types of footwear especially childrens. The test specimen size may be reduced slightly at width only; the length (70 1) mm shall not be reduced. However, it is preferred to test the materials themselves and, if necessary, introduce perforations or seams (o
40、r other design features) similar to that found in the forepart of the shoe.Table 1 Standard test conditions and number of test specimensType of material being testedTesting conditionsDry Wet ColdGrain leather 2 2 Coated leather 2 2 2Suede 2 Coated fabric 4 4Fabric 4 6.2 Dry testsPlace all the test s

Close the cabinet and start the cooling until the desired temperature. The test shall start after 30 min in the cold atmosphe
44、re.Warm the cold chamber slowly to room temperature after flexing to avoid condensation effects. After replacing the specimens cool the chamber and start the flexometer 30 min after reaching the desired temperature again.7 Test method7.1 PrincipleA rectangular test specimen is clamped in a flexing m
45、achine. One end of the test specimen is held in an upper clamp with the surface folded inwards so that these surfaces touch and the fold line is horizontal. It is then turned inside out and bent through 90 before being inserted in the lower clamp. In the lower clamp, the test specimen is folded so t
46、hat the reverse or flesh surface of the test specimen touch and the fold line is vertical.During the test, the clamps oscillate at a constant speed so that the test specimen is repeatedly flexed. The tests can be carried out with either wet or dry test specimens at room temperature or dry test speci
47、mens at sub-zero temperatures. After a predetermined number of cycles, the tests are stopped and the test specimen is visually examined for signs of damage or salt spue.7.2 ProcedureMark on the back of each test specimen the along direction of the material, e.g. with an arrow, and determine the requ
48、ired testing conditions. It should be noted that linings will be tested face down and uppers face up.7.2.1 Carry out the test in the conditioned standard atmosphere specified in ISO 18454.7.2.2 If conducting a wet test, use the prepared test specimen (6.3).7.2.3 If conducting a cold test, follow the
49、 instruction of 6.4 and start the tests. Ensure that the atmosphere surrounding the flexing machine is at the required temperature usually (-5 2) C.7.2.4 Load each test specimen as follows.7.2.4.1 Open the upper and the lower clamp up to the twice thickness of specimen, at least.7.2.4.2 Turn the motor as far as the lower edge of the upper clamp stands parallel to the upper edge of the fixed lower clamp.7.2.4.3 Fold the test specimen with the surface inwards, so that the two longer ed
