1. In-House Verification: The Model 615 Impact Rig
To guarantee that every batch of safety boots leaving our Gaomi facility complies strictly with EN ISO 20345:2022 and ASTM F2413-18, GUANGHE operates an in-house certified Model 615 drop-hammer impact tower and 15kN hydraulic compression tester.
Under the standard test protocol, a 20 kg steel striker is dropped from a calibrated height of 1,020 mm, delivering exactly 200 Joules of kinetic impact energy onto the safety toe cap. A modeling clay cylinder placed inside the toe cap measures residual clearance. For size EU 42, minimum clearance must remain β₯ 14.0 mm with zero cracking through the toe structure.
