Safety boots must comply with the European standard EN ISO 20345:2011, which sets out basic requirements and optional features for safety footwear. This standard defines the level of protection through classifications (S1, S2, S3, S4, S5), and additional symbols for specific features such as slip resistance (SRA, SRB, SRC). At RAG Tailors, all models are certified according to this standard and undergo rigorous tests for resistance to impact, compression, puncture and antistatic properties. Some models also meet specific requirements such as thermal insulation (CI) or protection against electrical hazards (ESD).
