Huangdao shoes Xiaobian to introduce the performance of labor protection shoes

Impact test with a specified weight of steel impact hammer, Baotou under the impact of the gap height should be less than the specified value, and Baotou in the direction of the test axis should not appear any penetrating crack. It is worth noting that the weight, specifications, impact height of impact hammer and construction of testing machine are different in each country.

Testing machine is provided with a pressing plate, plate provided with a test pin test nail as the head of a truncated tip, nail head hardness should be greater than 60 HRC. The sole specimen is placed on the chassis of the test machine, the position can make the test nail through the bottom of the puncture, the test pin to 10 mm/min + 3 mm/min of the speed through the soles, until the penetration so far, record the maximum force required. selec 4 points on each sole to test (in which at least 1 points in the heel), each point is not less than 30mm, and the distance from the bottom edge is greater than 10 mm. There is the bottom of the slide block, should be carried out between the block. 2 to 4 points in the test should be conducted from the plant where the bottom arris edge line 10-15 mm distance. If the humidity will affect the results, before the test should be soaked in the soles plus 20 degrees C + 2 degrees C in the water 16 + 1h.

Shoe after the regulated in the dry and wet atmospheric, clean ball filling shoe and put a metal probe device, using the specified resistance testing instrument and measurement in front of two probe and the probe between the resistance. Under normal circumstances, the conductive shoes require resistance should not be greater than l00K ohm; anti-static shoes require resistance should be between 100K ohm to 1000M ohm.
