What are the changes to puncture resistance in the new EN ISO 20345 standard? Key Updates Explained

The EN ISO 20345:2022 standard introduces significant updates to puncture resistance requirements for safety footwear, particularly for non-metallic inserts. While metallic inserts (P) retain the same 4.5 mm point test, non-metallic inserts now have two distinct classifications: PL (tested with a 4.5 mm point) and PS (tested with a 3 mm point under 1100 newtons force). This change allows for more precise differentiation of puncture protection levels and reflects advancements in non-metallic materials. Footwear labeling has also been updated to include these new designations, such as S1PS, S1PL, S3S, or S3L for non-metallic inserts, while maintaining S1P and S3 for metallic inserts. These revisions provide clearer guidance for purchasers and users about the specific puncture protection offered by different footwear models.

Key Points Explained:

  1. Unchanged Requirements for Metallic Inserts (P)

    • The testing method remains identical to previous standards
    • Uses a 4.5 mm diameter point for puncture testing
    • Maintains the same "P" marking system in footwear classification
  2. New Classification System for Non-Metallic Inserts

    • Introduces two distinct categories:
      • PL: Tested with larger 4.5 mm point (same as metallic)
      • PS: Tested with smaller 3 mm point under 1100N force
    • Reflects different protection levels and material capabilities
    • Allows for more precise product differentiation
  3. Updated Footwear Labeling Conventions

    • New labeling combinations include:
      • S1PS/S1PL: Basic safety shoes with non-metallic puncture protection
      • S3S/S3L: Higher protection shoes with non-metallic inserts
    • Maintains existing S1P/S3 markings for metallic inserts
    • Provides clearer information about protection type at point of purchase
  4. Implications for Equipment Purchasers

    • Enables more informed selection based on specific workplace hazards
    • Allows comparison between different puncture protection technologies
    • May affect inventory management with expanded product classifications
    • Encourages manufacturers to develop specialized solutions for different risk profiles
  5. Technical Considerations

    • The 1100N force for PS testing represents a significant load requirement
    • Smaller 3mm point test simulates different real-world puncture scenarios
    • Maintains backward compatibility with existing metallic insert standards
    • Provides flexibility for manufacturers developing new composite materials

These changes ultimately create a more nuanced safety footwear market where purchasers can match specific workplace hazards with appropriate protection levels, particularly for environments where traditional metallic inserts may not be ideal.

Summary Table:

Key Change Description
Metallic Inserts (P) Unchanged: 4.5 mm point test, same "P" marking
Non-Metallic Inserts (PL/PS) New classifications: PL (4.5 mm point) and PS (3 mm point under 1100N force)
Updated Labeling New combinations: S1PS/S1PL (basic), S3S/S3L (higher protection)
Purchaser Implications Enables precise hazard matching and clearer protection level comparisons
