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 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On introducing these standards all national standards relating to safety toecaps and penetration resistant inserts were withdrawn leaving the manufacturers of these items with no means of demonstrating the performance of their products.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 been prepared to allow manufacturers to demonstrate the performance level of the toecaps and penetration resistant inserts before being inserted into the footwear.

The striker (see Figure 4) shall be made of steel with Rockwell hardness min. 60 HRC and shall consist of a wedge at least 60 mm long, the rectangular faces of which are at least 40 mm in height and subtend an angle of (90 ± 1)°. The apex where the faces meet shall be rounded to a (3 ± 0,1) mm radius. During the test the apex shall be parallel within ± 2° to the base of the clamping device. The base of the apparatus shall be of compact design, avoiding elastic structures as far as possible. It shall have a mass of at least 600 kg and a metal block of dimensions at least 400 mm × 400 mm × 40 mm deep shall be bolted to it. The apparatus shall be free standing on a flat and level floor which is sufficiently large and rigid to support the test equipment. Provision shall be made for a mechanism to catch the striker after the first impact so that the test specimen will be hit only once. Dimensions in millimetres 90 û

Figure 5 — Example of suitable design

of toe cap clamp The toe cap shall be held in position at the front end with a forked clamp which is fixed with a screw into one of the threaded holes, depending on the size of the toe cap. The toe cap shall be held at the rear end with a curved plate which is screwed to a sliding rail. The radiused plate lies over the flange at the back edges of the cap and pushes the cap against the forked clamp with a load of 100 N to 200 N. SIST EN 12568:2010

EN 12568:2010 (E) 14 The sliding rail is sprung such that when the toe cap is hit by the striker it can move back along its axis against the spring. To change the toe cap the curved plate is retracted by releasing the clamping handle. 5.2.2.1.3 Cylinders of modelling clay, with a diameter (25 ± 2) mm; the height shall be (28 ± 2) mm for toe caps up to and including size 5, and (30 ± 2) mm for toe caps above size 5. 5.2.2.1.4 Dial gauge, with an accuracy of 0,1 mm, working in a vertical sense, with a flat base to place the clay cylinder on, and a hemispherical upper sensor of (3,0 ± 0,2) mm radius exerting a vertical force of not greater than 250 mN. 5.2.2.2 Procedure Determine the test axis as described in 5.2.1.1. Use the toe cap as the test piece. Hold the test piece in the clamping device (5.2.2.1.2) so that when the striker hits it, the striker will project over the front and back of the toe cap. Position a cylinder (5.2.2.1.3) under the rear upper edge of the test piece in such a way that approximately € of its diameter is within the test piece and  of its diameter is protruding behind the rear edge and the centre of the cylinder matches the test axis as closely as possible (see Figure 6). At the time of the test, the temperature of the modelling clay shall be between 18 °C and 25 °C. Allow the striker to drop onto the test axis from the appropriate height to give an impact energy of (200 ± 4) J for toe caps designed for safety footwear or (100 ± 2) J for toe caps to be used in protective footwear. Measure, to the nearest 0,5 mm, the lowest height to which the cylinder has been compressed, using the dial gauge (5.2.2.1.4). This value is the clearance at the moment of impact.

The number of tests to be performed is stated in Table 1. If only one size is available (e.g. prototype), two pairs of samples shall be tested.

Both platens shall cover at least an area of diameter 150 mm, shall have a minimum hardness of 60 HRC and shall remain parallel during the application of the load. Any effect of eccentrically applied forces to the measurement shall be excluded as far as possible. 5.2.3.1.2 Cylinders, as described for the impact test (see 5.2.2.1.3). 5.2.3.1.3 Dial gauge, as described for the impact test (see 5.2.2.1.4). 5.2.3.2 Procedure Determine the test axis as described previously (see 5.2.1.1). Use the toe cap as the test piece. Position the test piece between the platens of the compression machine (5.2.3.1.1). A cylinder (5.2.3.1.2) is positioned under the rear upper edge of the test piece in a way that approximately € of its diameter is within the test piece and  is protruding behind the rear edge and the centre of the cylinder matches the test axis as closely as possible (see Figure 6). At the time of the test, the temperature of the modelling clay shall be between 18 °C and 25 °C. Compress the test specimen to a load of either (15 ± 0,1) kN for toe caps to be used for safety footwear or (10 ± 0,1) kN for toe caps to be used for protective footwear (see Figure 7). Reduce the load, remove the cylinder and measure, to the nearest 0,5 mm, the lowest height to which the cylinder has been compressed, using the dial gauge described in 5.2.3.1.3.

NOTE This value is the compression clearance at the moment of highest compression. The number of tests to be performed is stated in Table 1. If only one size is available (e.g. prototype), two pairs of samples shall be tested.

5.3.1 Preliminary examination Examine the toe cap visually inside and outside for signs of corrosion under the coating and for corrosion occurring where the coating has broken down. Measure the longest distance across each area of corrosion and note the number of such areas. 5.3.2 Corrosion test procedure Remove any grease, silicone, wax or similar material which might be present on the surface. Prepare at least 300 ml of a 1 % (mass fraction) aqueous solution of sodium chloride as the test solution. Pour it into a dish sized at least 100 mm × 160 mm. The depth of the solution shall be ≥ 15 mm and it shall fill the dish up to a height of ≤ 10 mm from the glass plate. Cover the dish with a glass plate leaving a small opening. Dip two strips of white filter paper of dimensions at least 100 mm wide and 150 mm long into the test solution at one end so that the strips of filter paper become saturated with solution, the other ends being laid on the glass plate. Lay the toe cap to be tested flange down over the free end of one filter paper so that the whole flange is in contact with the wetted area and lay the other filter paper over the toe cap so that the greatest possible area of the nose of the cap and its upper surface is in contact with the filter paper (see Figure 8). Ensure that the filter paper remains saturated throughout the test. After 48 h remove the filter paper and examine the toe cap for signs of corrosion. Measure the longest distance across each area of corrosion and note the number of such areas. SIST EN 12568:2010
