Impact resistance of Baotou
The impact test is carried out with a steel impact hammer with a specified weight. The height of the gap in Baotou under the impact of Baotou should be less than the specified value, and there should not be any penetrating cracks in the direction of the test axis in Baotou. It is worth noting that the weight, specifications, impact height and the structure of the test machine are different in the national standards, and the actual test should be distinguished.
Anti piercing performance
The test machine is equipped with a pressure plate, and the test board is equipped with a test nail. The test pin is a cutting head, and the hardness of the nail head should be greater than 60HRC. The sole specimen of the toe shoe sole is placed on the chassis of the test machine. The position can make the test nail pierce through the outer bottom. The test nail pierces the sole with the speed of 10 mm/min + 3 mm/min until the maximum force is recorded until the penetration is penetrated. 4 points on each sole are selected for testing (at least 1 points in the heel). The distance between the points is not less than 30mm, and the distance from the bottom edge is greater than 10 mm. The bottom of the anti slide block should be punctured between blocks. The 2 points in the 4 points should be tested at a distance of 10-15 mm from the edge line of the planting floor. If humidity affects the result, the shoe sole should be immersed in the deionized water at 20 + 2 1H before the test. 16 +.
Electrical properties of conductive shoes and antistatic shoes
After adjusting the toe shoes in the dry and wet atmosphere, a clean steel ball is filled into a human shoe and placed on a metal probe device. The resistance of the first two probes and third probes is measured using a specified resistance test instrument. Under normal circumstances, conductive shoes require resistance should not be greater than l00K ohms; antistatic shoes require resistance between 100K ohms and 1000M ohms.
