The two primary standards governing safety footwear globally are ASTM F2413 (previously ASTM F2412) and EN ISO 20345. These standards ensure footwear meets minimum safety requirements for impact resistance, compression, puncture protection, and other hazards. While ASTM F2413 is widely adopted in North America, EN ISO 20345 is the benchmark in Europe and many other regions. Both standards undergo periodic updates to reflect evolving workplace safety needs and technological advancements in materials and design.
Key Points Explained:
-
ASTM F2413 (U.S. Standard)
- Developed by ASTM International, this standard specifies performance requirements for safety toe caps (steel, composite, or aluminum), metatarsal protection, and puncture-resistant soles.
- Key tests include:
- Impact Resistance: Toe cap must withstand a 75-lb weight dropped from 1 foot (200 joules).
- Compression Resistance: Toe cap endures 2,500 lbs of static force.
- Optional certifications for electrical hazard protection, static dissipation, and ladder grip.
- Replaced ASTM F2412 in 2005, with updates like F2413-18 reflecting newer testing protocols.
-
EN ISO 20345 (European/International Standard)
- Mandates a 200-joule toe impact test (similar to ASTM) but includes additional classifications:
- SB (Basic): Minimal requirements (anti-slip soles, closed heels).
- S1-S5: Progressive protections (oil resistance, energy absorption, waterproofing).
- Unique features:
- Penetration Resistance: Midsole must withstand a 1,100-newton nail.
- Slip Resistance: Tested on ceramic tiles and steel surfaces with glycerol.
- Updated in 2022 (EN ISO 20345:2022) to include enhanced slip resistance and clearer labeling.
- Mandates a 200-joule toe impact test (similar to ASTM) but includes additional classifications:

Regional Adoption & Industry-Specific Needs
- ASTM F2413 dominates in industries like U.S. construction and manufacturing.
- EN ISO 20345 is critical for EU compliance and sectors like oil/gas (where anti-static properties are vital).
- Other standards (e.g., CSA Z195 in Canada) often align with these benchmarks but add localized requirements (e.g., metatarsal guards for forestry work).
-
Purchasing Considerations
- Certification Marks: Look for stamped labels (e.g., "ASTM F2413-18" or "EN ISO 20345:2022 S3").
- Material Trade-offs: Composite toes (lighter, non-conductive) vs. steel toes (durable but heavier).
- Fit & Comfort: Standards don’t address ergonomics—prioritize brands with adjustable features (e.g., cushioned insoles).
-
Emerging Trends
- Hybrid designs merging ASTM/EN ISO features for global supply chains.
- Smart footwear integrating sensors for real-time hazard alerts (not yet standardized).
For specialized environments (e.g., electrical work or chemical labs), always cross-check supplemental standards like OSHA 29 CFR 1910.136 or ISO 20347 for occupational-specific needs.
Summary Table:
| Standard | Key Requirements | Region | Unique Features |
|---|---|---|---|
| ASTM F2413 | 75-lb impact, 2,500-lb compression resistance | North America | Optional electrical hazard protection |
| EN ISO 20345 | 200-joule impact, 1,100N penetration resistance | Europe/Global | Slip resistance, waterproofing (S1-S5) |
