20、pe This European Standard specifies a test method for assessing the fatigue resistance of steel shanks of at least 100 mm in length used for the reinforcement of the waist region of womens shoes and of some mens and childrens shoes. NOTE Steel shanks below 100 mm in length cannot be reliably tested

21、by this method. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendme

23、nd components for footwear. 3 Definitions For the purposes of this standard the following definition applies. 3.1 fatigue resistance the resistance of a shank, under specified conditions, to repeated loading cycles 4 Apparatus and materials A test machine shall be used to measure the fatigue resista

24、nce of steel shanks. For multi station machines each station shall include the items described in a) to d). a) A fixed lower jaw with flat hardened steel face plates of height 32 mm 2 mm and of width suitable to securely clamp the shank. b) An adjustable upper jaw with flat hardened steel face plate

25、s with a means of exerting a force of 49 N 2 N on the shank perpendicular to the plane of the lower clamp faces at a rate of four cycles per second. One complete cycle being the application of the load in a forward and reverse direction as in a simple harmonic motion. An illustration of suitable upp

26、er and lower jaw configuration is given in Figure 1. c) A method of counting the number of complete cycles up to break of the specimen. d) A method of controlling the clamping force of the jaws see items a) and b), to 4 900 N mm 50 N mm. NOTE A torque wrench is suitable. 5 Sampling and conditioning

27、The test specimen shall be a complete shank. At least four samples of each type of shank shall be tested. Condition samples for 48 h prior to testing in a controlled atmosphere in accordance with EN 12222. Tests shall be carried out in a suitable conditioned atmosphere in accordance with EN 12222, o

28、r, where this is not possible tests shall be carried out within 15 minutes of removing the test specimen from the conditioned atmosphere.EN 12958:2000 4 BSI 6 July 2004 6 Test method The shank is clamped at its rear end as it would be in a shoe and bent as a cantilever beam by an alternating force a

29、pplied to the shank. The number of loading cycles required to break the shank is termed the fatigue life. Insert the heel end of the shank centrally in the lower jaw see 4a) so that 32 mm of shank are clamped with the end of the shank level with the bottom edge of the jaw and the specimen is perpend

30、icular to the clamping forces of the lower jaw. Close and tighten the lower jaw see 4a) ensuring that the torque exerted at the upper edge of the jaw is 4 900 N mm by using a device according to 4d). Such a high torque does not need to be applied to the lower edge of the clamp, but apply sufficient

31、to ensure that the lower edge is secure and that the faces of the jaws remain parallel. Place the upper jaw see 4b) on the specimen so that the distance between the top edge of the lower clamp see 4a) and the centre of the upper jaw see 4b) is 70 mm 2 mm. Uniformly close and tighten the upper jaw se

32、e 4b) ensuring that the total torque exerted is 4 900 N mm see 4d). 7 Expression of results Operate the testing machine and record the total number of load cycles as each specimen breaks. For each specimen report the total number of load cycles to break and calculate the arithmetic mean of the four

33、results. 8 Test report The test report shall include the following information: a) results, expressed in accordance with Clause 7; b) reference to this test method; c) full description of the samples tested including commercial styles codes, colours, nature, etc.; d) the number of test specimens if

34、other than four; e) any deviations from this standard method; f) date of testing.EN 12958:2000 BSI 6 July 2004 5 Figure 1BS EN 12958:2000 BSI 389 Chiswick High Road London W4 4AL BSI British Standards Institution BSI is the independent national body responsible for preparing British Standards.
