What are the specifications of labor insurance shoes for labor insurance products?
Test machine is provided with a pressing plate provided with a test for a nail, nail test cut tip head, the nail head hardness should be greater than 60HRC. Placing the sole sample on the chassis of the test machine, the position allows the test pins to pierce through the outsole. The test pin pierces the sole at a rate of 10 mm/min + 3 mm/min until the penetration is achieved, recording the maximum force required. Each shoe is selected on 4 points for testing (at least 1 points in the heel), each point is no less than 30mm, and the distance from the inner bottom edge is greater than 10 mm. The bottom of the block should be pierced between the blocks. The 2 points in the 4 points shall be tested at a distance of 10-15 mm from the edge of the base wall. If humidity affects the result, the sole shall be dipped in deionized water of 20 + 2 DEG C before testing, 16 + 1h.
The impact test of steel hammers with specified weight shall be carried out. When the impact of Baotou is reached, the gap height under Baotou shall be less than the specified value, and Baotou shall not appear any penetrating cracks in the direction of the test axis. It is worth noting that the standards of hammer, weight, specification, impact height and structure of test machine are different in national standards, and should be distinguished in actual test.
By adjusting the shoe in dry and wet air, clean fill people inside the shoe and placed on the metal probe device on resistance test instrument using the provisions of the preceding two resistance measurement probe and third probe between. Under normal circumstances, conductive shoes require resistance should not be greater than l00K ohms; anti-static shoes, resistance requirements should be 100K ohms
