These normative references are cited at the appropriat
19、e places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication

ISO 5893 Rubber and plastic test equipment - Tensile, flexural and compression types (constant
21、 rate of traverse) - Description. 3 Definitions For the purpose of this standard the following definition applies: compression energy: the energy in joules corresponding to the deformation of a material under a fixed force of 5 000 newtons. 4 Apparatus and material The following apparatus and materi
22、al shall be used: 4.1 Tensile-testing machine 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 10 mm/min 2 mm/min. A low-inertia machine having autographic force recording facilities is required.

All test specimens
26、shall be conditioned in accordance with EN 12222 before testing. Minimum time of conditioning 24 hours, and minimum two test pieces by size are necessary. 6 Test method Place the outsole with the heel on a steel base and press the test punch against the outsole unit from the inside at the centre of
27、the heel area at a test rate of 10 mm/min 3mm/min until a force of 5 000 newtons is obtained. 7 Expression of results Plot a load/compression curve (see figure 2) for each test and determine the compression energy E in joules, rounded to the nearest 1 J, from the equation: where F is the applied for
