Each tool undergoes 1000V dielectric testing before leaving the factory
Flame retardant tested using industrial-grade methane gas flame at 20mm height for 10 seconds; flame height must not exceed 120mm within 20 seconds post-test
Submerged 1000V high-voltage electrical test passed
Ultra-low temperature test at -40°C for 2 hours with no insulation cracking or damage
High temperature aging test at 70°C for 168 hours with no insulation damage
Impact test from 0.6m drop height with no cracking or damage
Adhesion and tensile strength tests on insulation layer with 20N force applied for 3 minutes; no peeling or loosening observed
Abrasion and indentation tests at 70°C with repeated wiping and dielectric testing to ensure insulation integrity and legible markings
