Performance validation should focus on the specific protective function. For protective clothing, check the GSM (grams per square meter) and seam reinforcement to ensure tear resistance. For safety gloves, evaluate the EN 388 levels for abrasion, blade cut, tear, and puncture resistance. For safety footwear, ensure they feature steel or composite toes rated for impact and compression. Always request third-party lab test reports (such as from SGS or TUV) rather than relying solely on factory-issued certificates.
