what are the specifications and standards of safety shoes in different regions and countries

European common market safety standard (en344.1:1992) according to the test methods and specifications of this standard, safety shoes can be divided into three types:

. En345.1:1992: safety shoes for professional use, with steel plate built in the toe cap, which can prevent the impact force equal to 200 joules (J)< En346.1:1992: protective shoes for professional use, with built-in steel plate on the toe cap, can resist impact force equal to 100 joules (J)< En347.1:1992: professional work shoes, no steel plate in the toe< American Standard (ansi-z41-1991) according to the resistance of shoes to compression and impact, safety shoes with protective toe cap can be divided into three types< The Australian standard (as / NZS 2210.1:1994) divides safety shoes into four categories, 1t includes: heavy duty safety shoes, medium duty safety shoes, light duty safety shoes and waterproof safety shoes 4. National standard of the people’s Republic of China . G.b.4014-83 leather safety shoes. G.b.7054-86 rubber faced anti smashing safety shoes 5. Japanese standard (j1s-t-8015:1983) introduction of national standard 1 Product safety performance and physical performance standards: inspection items executive standard requirements impact resistance test (mm) ld50-94 anl: impact hammer 23kg, drop height 900mm, after impact, Shoe clearance ≥ 15 pressure test (mm) ld50-94 anl: 15kn after pressure test shoe clearance ≥ 15 puncture resistance (n) gb12017-1989 super class: ≥ 1100 (environmental conditions 18-28 ℃) insulation test (6kV) gb12011-2000 test voltage 6kV, duration 2min, leakage current & lt; 5 Ma antistatic performance test(Ω) Gb4385-95 resistance value 105 Ω- one hundred and nine Ω oil resistance gb16756-97, resistance to gasoline, kerosene, transformer oil and trimethylpentane solvent, expansion ≤ 12% high temperature resistance LD4-91, low heat resistance, heat resistance temperature 150 ℃ ± 5 ℃ thickness of the sole (mm) thickness of any part of the sole ≥ 6 wear resistance of the sole (mm) ≤ 10 folding resistance of the sole (mm) ≤ 12 peeling strength (n / cm) ≥ 59 hardness of the sole (Shore A) 55-72
