Special alloy steel, Cutting edges induction hardened, Chrome plated Special steel, Cutters induction hardened, Chrom plated Our VDE certified products (pliers, side cutters, needle nose pliers) are subjected to tests within the scope of TS EN 60900 Standard. Products in these tests Dielectric Experiment: They are exposed to electricity under 10000 Volts for 3 minutes. Adhesion Test of Insulation: After being kept in the oven at 70 °C for 1 week, they are taken out of the oven and subjected to the stem stripping test under a force of 500 N for 3 minutes. Impact Test: After being kept at -25 °C for 2 hours, they are subjected to an isolated impact resistance test from the desired height with the weight determined according to the product to be tested. Trace Test: They are exposed to electricity under 5000 Volts with a 2 kg conductive material on the insulation for 3 minutes. Flame Test: Flame is applied to the insulation for 10 seconds. After the flame is removed, the flame on the burning part of the insulation should not exceed 120 mm. That's why electrical/electronic industry professionals prefer our VDE certified products.
