Safety shoes are the general term of safety shoes and protective shoes, which generally refer to shoes worn in different working places to protect feet and legs from foreseeable injury. Safety shoes included safety shoes for women and for men. This article will introduce different performance tests of safety shoes.
Impact resistance
The steel impact hammer with the specified weight shall be used for the impact test. When the Baotou is impacted, the gap height under the Baotou shall be less than the specified value, and there shall be no penetrating crack in the direction of the test axis. It is worth noting that the weight, specification, impact height, and structure of the testing machine of impact hammer are different in national standards, which should be distinguished in actual testing.
Puncture resistance
A pressing plate is installed on the testing machine, and a test nail is installed on the pressing plate. The test nail is ahead with the tip cut off, and the hardness of the nail head shall be greater than 60HRC. Place the sole sample on the chassis of the testing machine so that the test nail can pierce through the outsole. The test nail pierces the sole at the speed of 10 mm/min ± 3 mm / min until it penetrates. Record the maximum force required. Select 4 points on each sole for the test (at least 1 point is at the heel), the distance between each point is not less than 30mm, and the distance from the inner sole edge is more than 10mm. The bottom with an anti-sliding block shall be pierced between blocks. Two of the four points shall be tested within 10-15 mm from the edge line where the planting bottom ridge is located. If the humidity will affect the results, immerse the sole in deionized water at 20 ℃± 2 ℃ for 16 ± 1H before the test.
Due to the limited space, there are still some performance tests that cannot be written in detail. Kameymall will continue to elaborate for you in the next article.
