Understanding the Testing Standards for Xinjiaxu Anti-Smash Safety Shoes

The quality of anti-smash protective shoes depends mainly on factors like materials, workmanship, and test results. Only shoes that pass rigorous testing can truly protect your safety and toes from injury. Here are the key test standards used by Xinjiaxu Safety Shoes:

Anti-Smashing Test

A steel impact hammer of specified weight is used to impact the toe area. The gap under the toe after impact should be less than the limit, and there should be no penetrating cracks along the impact axis. National standards vary on test hammer specifications, impact heights, and machine setups.

Puncture Resistance Test

A pressure plate with a truncated conical test nail (hardness over 60HRC) is used. The shoe sole is placed under the plate and nail, which punctures at 10±3 mm/min until penetration. The maximum required force is recorded. Four points on each sole are tested, at least one at the heel, spaced 30mm apart and over 10mm from edges. Points are also tested within 10-15mm of base edges. Soles may be soaked before testing if humidity affects results. 

Electrical Properties Test 

For conductive/anti-static shoes, resistance between steel balls filled in the shoe on a probe device and between first two probes and third probe is measured using a specified instrument. Conductive shoes should have resistance under 100k ohms, anti-static between 100k-100M ohms.
