When sourcing work boots, compliance with regional safety standards is non-negotiable. For the European market, ensure products carry the CE mark and meet EN ISO 20345:2011 standards. For the United States, boots must comply with ASTM F2413-18. Key protection categories to verify include SB (Safety Basic), S1P (Anti-static and penetration resistance), and S3 (Water resistant and penetration resistance). Always request valid test reports from accredited third-party labs like Intertek or SGS to ensure the steel or composite toes can withstand an impact of at least 200 Joules.
