The standard European classifications for safety footwear are defined under EN ISO 20345:2011, which outlines six primary protection levels (SB to S5) and additional variants (SBP, S1P, S2P). These classifications specify progressive safety features, from basic toe protection to advanced resistance against water, penetration, and static electricity. The standard ensures footwear meets rigorous safety benchmarks for industrial and hazardous environments, with clear labeling to guide purchasers in selecting appropriate protection.
Key Points Explained:
-
Governing Standard:
- The current European standard is EN ISO 20345:2011, replacing earlier versions like ISO 20345:2004. This harmonized standard ensures consistency across EU member states.
- Compliance is mandatory for safety footwear sold in Europe, with CE marking indicating conformity.
-
Primary Protection Levels:
-
SB (Basic Protection):
- Minimum requirement: 200-joule toe cap impact resistance (e.g., steel or composite toe).
- No additional features; foundational for all safety footwear.
-
S1 (Enhanced Protection):
- Includes SB features plus:
- Enclosed heel for stability.
- Antistatic properties (dissipates static electricity).
- Energy absorption in the heel.
- Includes SB features plus:
-
S2 (Water Resistance):
- Builds on S1 with:
- Water-resistant upper (tested for 60 minutes).
- Builds on S1 with:
-
S3 (Penetration Resistance):
- Adds to S2:
- Penetration-resistant midsole (e.g., steel or Kevlar).
- Cleated sole for slip resistance.
- Adds to S2:
-
S4 (All-Rubber/Polymeric):
- Fully waterproof construction (e.g., rubber boots).
- Includes S1 antistatic properties.
-
S5 (Advanced Protection):
- Combines S4 with:
- Penetration-resistant midsole.
- Cleated outsole.
- Combines S4 with:
-
SB (Basic Protection):
-
Variant Classifications (P-Suffix):
-
SBP/S1P/S2P:
- Includes penetration-resistant midsoles without other S3/S5 features.
- Example: S1P = S1 + penetration resistance.
-
SBP/S1P/S2P:
-
Additional Safety Codes:
- HRO: Heat-resistant outsole (withstands 300°C for 60 seconds).
- E: Energy-absorbing heel.
- WRU: Water-resistant upper (separate from S2 classification).
- CI: Cold insulation.
-
Practical Implications for Purchasers:
-
Workplace Requirements:
- Heavy industries (e.g., construction) typically require S3 or S5.
- Electrical work mandates antistatic (S1–S5) or conductive options.
-
Material Choices:
- Leather uppers (common in S1–S3) vs. rubber (S4/S5).
- Composite vs. steel toes for weight reduction.
-
Certification Labels:
- Look for EN ISO 20345:2011 and specific codes (e.g., "S3 WRU") on product tags.
-
Workplace Requirements:
-
Future Considerations:
- Emerging materials (e.g., lightweight composites) may influence updates to standards.
- Sustainability trends could drive eco-certifications alongside safety metrics.
By understanding these classifications, buyers can align footwear choices with occupational hazards, ensuring both compliance and worker safety.
Summary Table:
| Classification | Key Features | Common Use Cases |
|---|---|---|
| SB | 200-joule toe cap impact resistance | Basic industrial environments |
| S1 | SB + antistatic, enclosed heel, energy absorption | General workshops, light industrial |
| S2 | S1 + water-resistant upper | Wet or damp conditions |
| S3 | S2 + penetration-resistant midsole, cleated sole | Construction, heavy industry |
| S4 | Fully waterproof, antistatic | Chemical handling, wet environments |
| S5 | S4 + penetration-resistant midsole, cleated sole | Extreme conditions, oil rigs |
| SBP/S1P/S2P | Penetration-resistant midsole (no cleated sole) | Light-duty penetration hazards |
| HRO | Heat-resistant outsole (300°C for 60s) | Welding, foundries |
| E | Energy-absorbing heel | Prolonged standing |
| WRU | Water-resistant upper | Wet environments (separate from S2) |
| CI | Cold insulation | Freezers, outdoor winter work |
