Suitable safety shoe products. Our company is a professional safety shoe manufacturer. Next, we will teach you how to test the puncture resistance of safety shoes:
Test method for puncture resistance of safety shoes
1. Install a pressure plate on the testing machine. The pressure plate is equipped with a test nail. The test nail is a head with the tip cut off. The hardness of the nail head should be greater than 60HRC.
2. Place the shoe sole sample on the chassis of the testing machine in such a position that the test nail can pierce through the outsole. The test nail pierces the sole at a speed of 10 mm/min ± 3 mm/min until it penetrates, and record The amount of force required.
3. Select 4 points on each sole for testing (at least 1 point is at the heel). The distance between each point is not less than 30mm and the distance from the edge of the insole is greater than 10mm. There is a bottom with anti-slip blocks, which should be pierced between the blocks.
4. Two of the four points should be tested within a distance of 10-15 mm from the edge line where the bottom corrugation is located. If humidity will affect the results, the soles should be immersed in deionized water at 20℃±2℃ for 16±1h before testing.
The above is the test method for the puncture resistance of safety shoes. I hope you can better choose safety shoes after understanding it.
