On introducing these standards all national standards relating to safety toecaps and pe
23、netration resistant inserts were withdrawn leaving the manufacturers of these items with no means of demonstrating the performance of their products. This European Standard has been prepared to allow manufacturers to demonstrate the performance level of the toecaps and penetration resistant inserts
24、before being inserted into the footwear. BS EN 12568:2010EN 12568:2010 (E) 6 1 Scope This European Standard specifies requirements and test methods for toe caps and inserts with resistance against mechanical penetration, intended to function as components of PPE footwear (e.g. as described by EN ISO

34、d defects of splitting or delaminating between material layers. 4.2.2 Dimensions 4.2.2.1 Internal length When measured in accordance with the method described in 5.2.1, the internal length of toe caps shall be not less than the appropriate value given in Table 2.

36、a flange, the inside width of the flange (e) shall be not greater than 10 mm, as shown in Figure 1. eZZKey e Width of the toe cap flange Figure 1 Illustration of width “e“ of the toe cap flange 4.2.3 Impact resistance When toe caps are tested in accordance with the method described in 5.2.2 at an en
37、ergy level of either (100 2) J (toe caps intended for protective footwear), or (200 4) J (toe caps intended for safety footwear), the clearance under the cap at the moment of impact shall be not less than the appropriate value given in Table 3. In addition the toe cap shall not develop sharp edges o
38、r any cracks passing through the material (i.e. through which light can be seen). 4.2.4 Compression resistance When toe caps are tested in accordance with the method described in 5.2.3, the clearance under the toe cap at a compression load of either (10 0,1) kN (toe caps intended for protective foot
39、wear) or (15 0,15) kN (toe caps intended for safety footwear) shall not be less than the appropriate value given in Table 3. In addition the toe cap shall not develop sharp edges or any cracks passing through the material (i.e. through which light can be seen). NOTE The provisions of 4.2, 4.3 and 4.
40、4 do not exclude a toe cap design incorporating perforations.

42、 than 2 mm in any direction. 4.4 Special requirements for non-metal toe caps Stability against ageing and environmental influence When non-metal toe caps are subject to each single one of the treatments described in 5.4 and thereafter tested in accordance with the method described in 5.2.2 at an ene
43、rgy level of either (100 2) J (caps intended for protective footwear) or (200 4) J (caps intended for safety footwear), the clearance under the cap at the moment of impact shall be not less than the appropriate value given in Table 3. In addition, the toe cap shall not develop sharp edges or any cra
44、cks passing through the material (i.e. through which light can be seen). 5 Test methods for toe caps 5.1 General One pair of samples of each size shall be tested. Exceptions are made for some properties, as specified in Table 1. Where repetitions lead to different results on equal samples, the worst
45、 value shall be reported as test result. If samples of only one size are available, two pairs shall be tested. Each one of the environmental treatments of 5.4 shall be applied to new samples. 5.2 Test methods for all types of toe caps 5.2.1 Determination of internal toe cap length 5.2.1.1 Determinat
46、ion of the test axis Position the left toe cap with its rear edge in line with a base line and draw its outline. Repeat the exercise with the right toe cap of the pair, positioning it at the same base line in such a manner that the outlines at the toe end of the toe caps coincide (see Figure 2). BS

48、ght and left toe caps intersect on the base line. Construct the perpendicular from the base line at the mid point of AB or CD. This constitutes the test axis of both toe caps. 5.2.1.2 Procedure Place the toe cap, open side down, on a flat surface. With an appropriate gauge, measure the internal leng
49、th l, along the test axis from the front inside to the vertical projection of the back edge between 3 mm and 10 mm above and parallel to the surface upon which the toe cap rests, taking the longest distance as the length l (see Figure 3).
