13 Appendix A Protective Toe Impact Resistance (I) 1 Summary of Method 1.1 Footwear shall be constructed and manufactured so that a protective toe cap is an integral and permanent part of the footwear. 1.2 Footwear with a protective toe cap is impacted with a specified force. 1.3 After impact, the height of the modeling clay cylinder is measured. 2 Apparatus 2.1 The apparatus as shown in Figure 5 consists of a frame structure that permits the impactor to be constrained to fall along a known and repeatable path The impactor consists of a steel weight having a mass of 22.7 ± 0.23 kg (50 ± 0.5 lb). The nose of the impactor is a steel cylinder having a diameter of 25.4 ± 0.8 mm (1 ± 0.03 in.) and length of 50.8 mm (2.0 in.). The impact side of the cylinder has a smooth spherical surface with a radius of 25.4 ± mm (1.00 ± in.). The longitudinal centerline of the cylinder is parallel and coincident with mm (0.125 in.) to the symmetry of its vertical axis Apparatus incorporates a means of measuring the velocity at impact with a tolerance of ±2 %. The use of a velocity metering system allows for determining the time required for a 25.4-mm (1-in.) wide blade to pass completely through a beam of light prior to the impactor striking the specimen. The result, referred to as gate time, is measured in milliseconds (ms). The speed in in./s can be calculated using the following formula: where: V = velocity in in./s, and = gate time in ms. t g V = 1000 t g 2.2 The base of the apparatus consists of a steel plate with a minimum area 0.3m 2 (1 ft 2 ) and minimum thickness of 25.4 mm (1 in.). The base is anchored to a structure having a minimum mass of kg (2000 lb) to provide sufficient stability to the apparatus before, during, and after testing. 2.3 Sampling 7

15 Men s footwear specimens shall be obtained from size Women s footwear specimens shall be obtained from size The specimens shall be obtained by completely removing the toe portion of the footwear. This is done by cutting across the width of the footwear 25.4 ± 3.2 mm (1 ± in.) behind the back edge of the protective toe cap and cutting the upper material back to the edge of the protective toe cap as shown in Figure 6. Figure 6 showing Specimen Prepared for Impact and Compression Testing 2.4 Prior to impact testing, modeling clay, kept at room temperature and formed approximately as a vertical cylinder, shall be placed under the protective toe cap to back rear edge of the cap positioned inside the specimens directly under the point of impact (see Figure 7) Modeling clay for the test forms shall be tested in accordance with Test frequency shall be no less than once every month. It is recommended that this quality test be conducted on a specimen just prior to its use during an impact test (see Figure 8) Weigh out a 50 ± 2g sample of modeling clay Form material into a 35 ± 2 mm (1.375 ± in.) cylinder and allow material to sit at room temperature for 24h The modeling clay cylinder shall be placed horizontally on the base plate at the center point of the impact tester A block having dimensions of 75 by 75 by 44 mm (3 by 3 by 1.75 in.), with a hole drilled in the center of the block that is 25mm (1in.) in diameter and 25mm (1in.) deep, is slipped onto the impact nose The block/impactor assembly is carefully lowered until the wooden block makes contact with the modeling clay cylinder. 9

16 2.4.7 The impactor assembly is released allowing full weight to compress the cylinder for 10s Immediately afterwards, the impactor assembly is raised and the modeling clay cylinder cut in half to measure A modeling clay cylinder having a compressed thickness of 15 ± 2 mm is acceptable to use in impact resistance. 2.5 Specimen Mounting Specimens are to be placed on the test apparatus base plate so that the sole is parallel with the base The specimen is positioned so that the longitudinal center of the nose of the impactor strikes the approximate center of the protective toe cap at a point that is 12.7 ± 1.6 mm (0.50 ± in.) toward the front as measured from the back edge of the protective toe cap (see Figure 7). Figure 7 showing Specimen Prepared for Impact and Compression Testing Figure 8 showing Apparatus for Modeling Clay Quality Test 10

17 2.5.2 The specimen is held in position during test by use of a clamping device as shown in Figure 9. NOTE: Dimensions are in inches (millimetres). Figure 9 showing Position/Clamping/Impact Arrangement 11

18 The stabilizing fork clamp device rests on the insert and can be adjusted by means of a screw The adjustment secures the specimen parallel to the base plate and prevents movement when the impactor strikes the specimen Clamping screw shall be tightened using a force less than 28 Nm (25in. lbs). 2.6 Procedure: When in place, the modeling clay cylinder shall be shaped having a base diameter of approximately 25mm (1in.) nominal and positioned so that the cylinder simultaneously makes contact with the insert/sock liner/footbed of the footwear and the dome of the protective toe cap. (See Note 1.) NOTE 1 A small piece of release paper such as wax paper or cellophane can be placed on either the bottom side or top side of the cylinder to prevent the modeling clay from adhering to either the insert/sock liner or dome To measure Impact 75 product footwear, the impactor is dropped from a height that results in an impact velocity of 2995 ± 61 mm/s (117.9 ± 2.4 in./s), creating an energy of J (75 ftlbf). NOTE 2 In a vacuum, the distance would be 457mm (18 in.). Due to friction and air resistance, the height used for the test is somewhat greater Release the impactor After impact raise and secure the impactor on test apparatus, carefully remove the clay cylinder from inside the specimen and measure the height of the modeling clay cylinder at its lowest point using a measuring device capable of measuring to the nearest 0.1 mm (0.004 in.) This value is reported as the impact minimum interior height clearance for the specimen. 2.7 Test Report Report the minimum height of the modeling clay cylinder, without rounding up, to the nearest 0.1 mm (0.004 in.) as the clearance result for the product category for all three specimens. 12
