7、a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represent
8、ed on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are dra
9、fted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International St
10、andard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Internat
11、ional Standard ISO 20866 was prepared by the European Committee for Standardization (as EN 12744:1999) and was adopted, under a special “fast-track procedure”, by Technical Committee ISO/TC 216, Footwear in parallel with its approval by the ISO member bodies.

This European Standard shall be given the status of a national standard, either by publication of an identic
14、al text or by endorsement, at the latest by March 2000, and conflicting national standards shall be withdrawn at the latest by March 2000. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard:
15、 Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

19、f traverse) - Description 3 Definitions For the purpose of this standard the following definition applies: delamination resistance: The transverse force required to delaminate a unit area of the insole material. 4 Apparatus and material The following apparatus and material shall be used: 4.1 Tensile
20、-testing machine (Dynamometer) The tensile-testing machine shall comply with the requirements of ISO 5893, to an accuracy corresponding to grade B, with a constant rate of traverse of 25 mm/min ? 5 mm/min. ISO 20866:2001(E) 2 ISO 2001 All rights reserved Page 5 EN 12744:1999 4.2 Pairs of solid cylin
21、ders Pairs of solid cylinders, each 38,92 0,02 mm in diameter, with provisions for attachment to the tensile-testing machine. The end faces of the cylinders shall be at right angles to their axes. The cylinders shall fit in the tensile-testing machine so that the line of action passes through the ax
22、is of the two cylinders. One pair of cylinders is required for each test piece. 4.3 Collars Collars, with internal diameters of 39,00 mm 0,03 mm, to keep the cylinders and test pieces coaxial during assembly. 4.4 Circular knife Circular knife, to cut a circular test piece of diameter 38,0 mm 1,0 mm.
23、 The inner surface of the knife shall be angled outward from the cutting edge at approximately 5 to the vertical so that when the test piece is cut it passes through the knife without damage to the edge of the test piece. 4.5 Press Press, or similar apparatus, capable of exerting a force of 5,00 kN
24、0,25kN on the assembly of cylinders and test piece. 4.6 Vernier calipers Vernier calipers, capable of measuring to an accuracy of 0,1 mm. 4.7 Polymer adhesive Polymer adhesive, solvent-based, chloroprene rubber type. NOTE: Suitable adhesives are most chloroprene rubber sole-attaching adhesives and c
25、ommercially available chloroprene rubber impact adhesives sold for household use. 5 Sampling and conditioning Using the circular knife described in 4.4, cut out three test pieces of diameter 38,0 mm 1,0 mm, from the shoe insoles, cut insoles or from the component as supplied. If the test pieces are
26、taken from the shoe insoles or cut insoles, sampling must be done according to prEN 13400:1998. Condition the test pieces according to EN 12222, for a minimum of 24 h. ISO 20866:2001(E) ISO 2001 All rights reserved 3 Page 6 EN 12744:1999 If a wet test is required cut out three additional test pieces
27、. 6 Test method 6.1 Measure the diameter of each test piece to the nearest 0,1 mm with the vernier calipers (see 4.6). Clean the end faces of the cylinders (see 4.2) to remove all traces of insole material and adhesive from previous tests and remove all traces of grease. 6.2 Assemble each pair of cy
28、linders with one of the test pieces using the following procedure: Coat the end faces of a pair of cylinders and both surfaces of a test piece with adhesive (see 4.7), and allow to dry for 20 min. Place the collar (see 4.3) over the end of one cylinder, place the test piece in the collar and press i
29、t lightly on to the cylinder face. Insert the end face of the other cylinder into the collar and press lightly on to test piece. Place the assembly of cylinders, test piece and collar into the press (see 4.5), exert a force of 5,00 kN 0,25 kN to press the cylinders on to the test piece with the coll
30、ar in position. 6.3 Remove the collars and leave the test assemblies in the conditioning atmosphere, according to EN 12222, for 24 h before proceeding further with the determination. 6.4 Fit the first test assembly into the tensile-testing machine and run the machine at a cross-head speed giving a c
31、ylinder separation speed of 25 mm/min 5 mm/min. Record the maximum force obtained. 6.5 Repeat the procedure for the other two test assemblies. Reject the result of any test in which the test piece shows failure of adhesion of the adhesive film either to the insole material or to a cylinder and repea
32、t the procedure on a further test piece. 6.6 For the test specimens that are to be tested wet: 6.6.1 Follow the procedure in 6.1 to 6.3 to procedure three test assemblies 6.6.2 Soak the three test assemblies in distilled water for (6,0 ? 0,5) hours. 6.6.3 Remove each test assembly from the water, an
