EN ISO 17707:2005 (E) 4 1 Scope This European Standard specifies a method for determining the flex resistance of outsoles. This method is

18、 intended to assess the effect of sole materials and surface patterns on cut growth. This method is applied to outsoles that, in accordance with the test mentioned in Clause 6, have a maximum longitudinal rigidity of 30 N. NOTE The method described in this standard is based on the method for the det

19、ermination of the flex resistance for outsoles described in EN ISO 20344. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenc

20、ed document (including any amendments) applies. EN 12222, Footwear - Standard atmospheres for conditioning and testing of footwear and components for footwear.

21、s of this European Standard, the following term and definition apply. flex resistance number of flexes that cause cut growth and/or initiation of cracks in the outsoles 4 Apparatus and material 4.1 The following apparatus shall be used: 4.2 Device for the measurement of the longitudinal rigidity of

22、outsoles (See Figure 1) 4.2.1 Smooth metal hinged plate, fixed to a rigid base with provision to reduce the friction between the heel of the outsole and the hinged plate. 4.2.2 Clamping device, to fix the forepart of the outsole to be tested to the rigid base. 4.2.3 Sensor, capable of measuring forc

23、es from 0 N to 50 N, to a tolerance of 1 %, fixed to the hinged plate (4.2.1) at a distance of 315 mm from the hinge.

24、s 4.3 Device for the measurement of the flex resistance of outsoles (See figure 2) 4.3.1 A mandrel of diameter (30 0,1) mm around which the outsole is flexed. 4.3.2 A means of firmly clamping the outsoles at both ends so that the flexing line is aligned with the axis of the mandrel. 4.3.3 A means of

25、 flexing the outsoles at a constant rate between 135 cycles per minute and 150 cycles per minute through an angle of (90 2) about the axis of the mandrel. 4.3.4 A means of counting the total number of flexing cycles.

26、2 Test piece at null flex position 3 Fixed bearing 4 Moveable bearing Figure 2 - Device for the measurement of the flex resistance of outsoles 4.4 Chisel (or cutting tool), to pierce the outsole, the dimensions of which are defined in Figure 3. NOTE A means of firmly clamping the outsole in a jig is

27、 advisable to minimise the risk of breaking the chisel as it is withdrawn from the outsole. EN ISO 17707:2005 (E) 7 Dimensions in mm Key 1 Right-angled sharp edge on both sides of blade from taper to point 2 Sharp edge Figure 3 Chisel 4.5 Device for the measurement of the cut length, in millimetres,

28、 to an accuracy of 0,1 mm. Either a graduated optical magnifier, a travelling microscope or graduated probe and optical magnifier is recommended. NOTE A graduated optical magnifier is seldom of much use in measuring cut lengths when the sole unit has heavy cleating. 5 Sampling and conditioning 5.1 I

29、f the test piece to be tested is taken from a complete item of footwear: 5.1.1 Carefully cut the upper of the shoe or boot from the outsole, but leaving any insole and lasted margin attached. 5.1.2 If the outsole has raised edge to its upper surface such as a lip or an imitation welt, this should be

30、 carefully scoured off the forepart area down to, but not beyond the insole surface. 5.2 If the test pieces are outsoles units, they should be bounded before testing the rigidity and flex resistance with a standard insole of correct size and shape, attaching this with adhesive and allowing it to dry

31、 for 24 h. Minimum three outsoles (covering if it is possible the full size range) should be tested. The characteristics of the insole for the preparation of the test piece are: Material: Cellulose board Thickness: (2 0,1) mm Apparent bulk density: (0,55 0,05) g/cm3All the test pieces shall be condi

32、tioned for 24 h according to EN 12222. Thickness and apparent bulk according to EN ISO 534. EN ISO 17707:2005 (E) 8 6 Rigidity test method 6.1 Preparation of the test pieces Mark the longitudinal axis of the outsole, XY, as it is shown in Figure 4. The flexing line is defined as the line at 90 to th

33、e longitudinal axis passing through it at one third of the distance XY from the toe at X. The flexing line is AC (See Figure 4). Figure 4 - Position of the flexing line Mark a point, for the later insertion of a cut as follows: Find the centre of line AC; this is the point where the cut is made. For

34、 cleated roles identify two adjacent cleats that are as close as possible to the centre of the line AC. Mark the sole midway between these cleats (see Figure 5).

35、 Longitudinal axis XY 4 Single incision parallel to the line of maximum stress Figure 5 Sole incision 6.2 Test procedure Clamp (4.2.2) the forepart of the outsole to the rigid base in such a way that the flexing line AC is aligned with the hinge axis of the base plate (4.2.1). Flex the outsole at a

36、bending rate of (100 10) mm/min until an angle of 45 has been reached and record the force in N 1 N. It is possible to add a lubricant under the heel to facilitate the test. 6.3 Selection criteria Outsoles requiring a force greater than 30 N to reach an angle of 45 are not subjected to flexing. EN I

37、SO 17707:2005 (E) 10 7 Flex resistance test method 7.1 Remove the heel from the outsole, if necessary, leaving sufficient of the forepart and waist to clamp it in the flexing machine (4.3) with the flexing line of the outsole AC located over the centre of the flexing mandrel in the maximum flexion (

38、see Figure 5). 7.2 Adjust the testing device so that the outsole is fully flexed. Re-check the alignment in the position of maximum flexion. Manipulate the machine until the outsole is in the maximum flexed extended or stretched state. 7.3 Lubricate the chisel (4.4) with soap and water. Push the chi

39、sel through the full thickness of the clamped outsole at the centre of the point marked in 6.1. The cut made by the chisel should be parallel to the flexing line. 7.4 With the outsole still in its fully flexed position, measure the length of the cut using the measuring device (4.5). Record this leng

40、th as L(o) to the nearest 0,1 mm. 7.5 Switch on the device and subject the outsole to 30 000 flexes. At the completion of 30 000 cycles, the testing device should not be left in the fully flexed position. 7.6 Adjust the device so that the outsole is fully flexed and measure again the length of the c

41、ut using the measuring device. Record this length as L(f) to the nearest 0,1 mm. 7.7 Calculate the amount of the cut growth as L(f)-L(o). 7.8 With the outsole still fully flexed examine its surface for any other cracks that have developed. Record their number and the length (to the nearest 0,5 mm) o

42、f the longest crack. Check also for any spontaneous cracks and record the longest one. 8 Test report The test report shall include the following information: a) results, expressed in accordance with Clause 7; b) full identification of the samples tested, including commercial style codes, colour, nat

43、ure, etc.; c) reference to this method of test; d) date of testing; e) any deviation from this test method.
