Steel head static pressure test method

1. Prepare the instruments required for inspection (steel head, plasticine height: 35mm, diameter: 22mm, caliper)

2. Inspection method: Place the steel toe cap at the center of the test machine platform, put plasticine at the highest point of the steel toe cap, and the outer edge of the plasticine should be perpendicular to the edge of the steel toe cap.safety shoes

3. Press the retaining button on the static pressure tester to lock the hydraulic jack and raise it at a speed of 5mm per minute. Raise the static steel head to 15KN. After one minute, open the locked hydraulic jack to remove it. Plasticine, the height of the plasticine is measured by the caliper, the lowest point of the plasticine is the measured value, the plasticine height is ≥22mm, the steel toe cap is judged to be qualified, and the plasticine height of the shoe inspection is ≥15mm to determine the protection of the toe safety shoes.
