33、t 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
34、 and materialThe following apparatus and material shall be used.1) EN 13400 is equivalent to ISO 17709.2) EN 12222 is equivalent to ISO 18454.DIN EN ISO 17694:2016-10 EN ISO 17694:2016 (E)5 5.1 Test machine, in accordance with ISO 5402-1:2011, 4.1 including the following.5.1.1 At least four pairs of
35、 clamps.

If required, temperatures down to -30 C can be used.6 Sampling and conditioning6.1 GeneralCut out the required number (see Table 1) of rect
40、angular 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 direction for non-leather materials and half perpendicular to this. For tes
41、t 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 in the shoe.For materials, cut test specimens from a range of positions
42、 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 test specimen of sufficient size from certain types of footwear especiall
43、y 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 (or other design features) similar to that found in the forepart of the s
44、hoe.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 specimens which will be tested dry in a standard controlled atmosphere c

Fill in distilled or deionised water until a minimum water depth of 10 mm. Place the glass dish in the desiccator. Reduce the pressure for 2 min under less the 4 k

Take the test specimens out of the desiccator and remove the rest of water with filter paper and start the wet tests immediate.DIN EN ISO 17694:2016-10 EN ISO 17694:2016 (E)7 6.4 Cold testsThe test machi
