26、the material. 3.5 test chemical chemical or mixture of chemicals that is used to determine the breakthrough time under the laboratory test conditions. The chemical will be one that can cause adverse effects to the human body by contact with the skin. EN 13832-1:2006 (E) 5 3.6 breakthrough time elaps

34、 minimum number of samples, i.e. separate items of footwear, to be tested in order to verify compliance with the requirements specified in Clause 6 and EN ISO 20344, together with the minimum number of test pieces to be taken from each sample, are given in Table 1. Wherever possible, test pieces sha

35、ll be taken from the whole footwear item unless otherwise stated. NOTE If it is not possible to obtain a large enough test piece from the footwear, then a sample of the material from which the component has been manufactured may be used instead and this should be noted in the test report. Where samp

36、les are required from each of three sizes, these shall comprise the largest, smallest and a middle size of the footwear under test. All test pieces shall be conditioned in a standard atmosphere of (23 2) C and (50 5) % relative humidity for a minimum of 48 h before testing, unless otherwise stated i

37、n the test method. The maximum time which shall elapse between removal from the conditioning atmosphere and the start of testing shall be not greater than 10 min, unless otherwise stated in the test method.

A suitable apparatus is illustrated in Figure 1 and comprises a base-plate (5) and an open-ended cylindrical

40、 chamber (4) that is held tightly against the test piece (6) by the wing nuts (1) mounted on the bolts (2). NOTE A hole of diameter approximately 50 mm may be made in the base-plate for the examination of the surface not in contact with the liquid. During the test, the opening in the top of the cham

41、ber shall be closed by a close-fitting plug (3). 4.2.2.2 Miscellaneous a) wash flask, for example a Becher glass b) absorbent paper or lint free textile fabric EN 13832-1:2006 (E) 7 Dimensions in millimetres 321 1245620 150100Key 1 Wing nut 2 Bolt 3 Close-fitting plug to seal the hole in top of the

The tes

43、t piece for the upper shall consist of a disc of diameter (120 10) mm, taken from the footwear (see Figure 2) or from the material intended for use in constructing the footwear. The lining shall be removed. NOTE During removal of the lining as small an amount as possible of polymeric material should

44、 be removed. For the sole, a disc of diameter (120 10) mm shall be taken from the fore part of the sole. Discs with a thickness of (2,5 0,1) mm shall be prepared according to the following steps: a) Remove the sole tread by splitting. b) Obtain the thickness of (2,5 0,1) mm by removing the interior

45、material. Except for the necessary handling during preparation, the surface in contact with the chemical shall be tested without any mechanical treatment. If there is seam in the sample upper, it shall be tested. EN 13832-1:2006 (E) 8 11Figure 2a) - Knee length rubber boot Figure 2b) - Shoe or low b
