EN 12568:2010 (E) 5 Introduction EN ISO 20345, EN ISO 20346 and EN ISO 20347 relate to safety, protective and occupational footwear which define the performance and
19、required properties of the footwear. On introducing these standards all national standards relating to safety toecaps and penetration resistant inserts were withdrawn leaving the manufacturers of these items with no means of demonstrating the performance of their products. This European Standard has
20、 been prepared to allow manufacturers to demonstrate the performance level of the toecaps and penetration resistant inserts before being inserted into the footwear. EN 12568:2010 (E) 6 1 Scope This European Standard specifies requirements and test methods for toe caps and inserts with resistance aga

33、oe caps are tested in accordance with the method described in 5.2.2 at an energy 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 val
34、ue 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). 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 c

40、ition, the toe cap shall not develop sharp edges or any cracks 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 repeti
41、tions lead to different results on equal samples, the worst 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
42、Determination of internal toe cap length 5.2.1.1 Determination 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
43、at the toe end of the toe caps coincide (see Figure 2). EN 12568:2010 (E) 10 Key 1 Test axis 2 Right cap 3 Left cap A, B, C, D Points where the outlines of the right and left toe caps intersect on the base line Figure 2 Determination of test axis (schematic illustration) Mark the four points A, B, C
44、 and D where the outlines of the right 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 appropria
45、te gauge, measure the internal length 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).
