The safety performance and physical performance standards of work shoes are actually not complicated. Saou work shoes are summarized as follows:
Impact resistance test (mm): Impact hammer 23kg, drop height 900mm after impact, shoe inner gap ≥15
Pressure resistance test (mm): After the pressure resistance test of 15KN, the shoe inner gap ≥ 15
puncture resistance (N): special grade: ≥1100 (environmental conditions 18-28℃)
Insulation performance test (6KV): Test voltage 6KV, duration 2min,
Leakage current<5mA
Anti-static performance test (Ω): resistance value 105Ω-109Ω
Oil resistance: resistance to gasoline, kerosene, transformer oil and trimethylpentane solvents,
Expansion≤12%
High temperature resistance performance: low heat resistance type, heat resistance temperature 150±5℃
