| Level | Includes |
|---|---|
| SB | Basic: 200J toe impact, 15kN compression |
| S1 | SB + closed heel + antistatic + energy absorption in heel |
| S1P | S1 + puncture resistance |
| S2 | S1 + water penetration/absorption resistance |
| S3 ✓ | S2 + puncture resistance + cleated outsole — Recommended for construction |
Additional Codes
| Code | Meaning |
|---|---|
| SRC | Slip resistance on both wet tile (SRA) and oily steel (SRB) |
| WR | Water resistant |
| HRO | Heat resistant outsole (300°C) |
| CI | Cold insulation |
| AN | Ankle protection |
Head-to-Head: ASTM vs EN ISO
| Feature | ASTM F2413 | EN ISO 20345 |
|---|---|---|
| Toe Impact | 75 ft-lbs (102J) | 200J (higher) |

Frequently Asked Questions
What does ASTM F2413 mean on safety shoes?
ASTM F2413 is the American standard for protective footwear. A shoe carrying this certification has been independently tested to meet specific impact, compression, and other protection requirements.
What is the difference between S1, S2, and S3 safety shoes?
S1 provides basic toe protection with closed heel and antistatic properties. S2 adds water resistance. S3 adds puncture-resistant midsole and cleated outsole. For construction, S3 is recommended.
What does SRC mean on safety shoes?
SRC is the highest slip resistance rating. It means the shoe has been tested on both ceramic tile with soapy water (SRA) and steel with glycerol/oil (SRB).
Is EN ISO 20345 the same as ASTM F2413?
No, but they serve the same purpose. EN ISO 20345 is the European/international standard; ASTM F2413 is the American standard. EN ISO 20345 generally requires higher impact protection (200J vs 102J).
