The current European standard for safety footwear is EN ISO 20345:2011, which supersedes earlier versions like ISO 20345:2004. This standard mandates a minimum 200-joule impact resistance for toe caps (SB classification) and introduces progressive protection levels (S1–S5) with additional features like antistatic properties, water resistance, and penetration resistance. Specialized variants (e.g., S1P, S3) and supplementary protections (HRO, P) address specific workplace hazards. Compliance ensures footwear meets rigorous safety, durability, and ergonomic requirements for industrial use.
Key Points Explained:
-
Core Standard:
- EN ISO 20345:2011 is the active European standard, replacing ISO 20345:2004. It harmonizes safety requirements across EU member states, ensuring consistent testing and certification.
-
Basic Protection (SB):
- All certified footwear must include a 200-joule toe cap (tested by dropping a 20kg weight from 1m height). This baseline (SB) protects against crushing impacts common in construction or manufacturing.
-
Progressive Classifications (S1–S5):
- S1: Adds antistatic properties (dissipates static electricity) and an enclosed heel for stability.
- S2: Includes water resistance (upper materials resist water absorption for 60 minutes), ideal for wet environments.
- S3: Combines S2 features with penetration-resistant midsoles (tested against a 1100N nail) and cleated soles for slip resistance.
- S4/S5: Covers all-rubber/polymeric boots (e.g., Wellington-style), with S5 adding penetration resistance and cleats.
-
Specialized Variants:
- "P" Suffix (e.g., S1P): Indicates penetration-resistant midsoles even in lower classifications.
- HRO: Heat-resistant outsoles withstand temperatures up to 300°C for 60 seconds, critical for welding or foundries.
-
Additional Protections:
- Electrically Insulating (EI): Isolates against high-voltage hazards.
- Metatarsal Guards (M): Shields the upper foot from heavy falling objects.
- Fuel/Oil Resistance (FO): Prevents sole degradation in chemical environments.
-
Certification & Marking:
- Compliant footwear bears the CE mark and a shield icon with the standard number (e.g., "EN ISO 20345:2011 S3"). Labels must detail all protections for traceability.
-
Workplace Relevance:
- S1/S2: Light industrial or indoor settings (e.g., warehouses).
- S3/S5: High-risk sectors like construction, oil/gas, or utilities.
- HRO/P: Specialized roles in metalworking or electrical maintenance.
For purchasers, selecting the right classification hinges on hazard assessments—balancing worker safety with cost efficiency. For example, S3 suits most construction sites, while S1 may suffice for dry, low-risk environments.
Summary Table:
| Classification | Key Features | Common Use Cases |
|---|---|---|
| SB | 200-joule toe cap | Basic impact protection |
| S1 | Antistatic, enclosed heel | Light industrial, dry environments |
| S2 | Water-resistant upper | Wet or humid workplaces |
| S3 | Penetration-resistant midsole, cleated soles | Construction, high-risk sectors |
| S4/S5 | All-rubber/polymeric boots (S5 adds cleats) | Chemical or oil-exposed areas |
| HRO | Heat-resistant outsole (300°C) | Welding, foundries |
| P | Penetration-resistant midsole | Hazardous ground conditions |
