ISO 22568-2:2019

Overview

ISO 22568-2:2019 specifies requirements and test methods for non-metallic toecaps used as components of PPE footwear (for example footwear covered by ISO 20345 and ISO 20346). The standard defines performance, dimensional and durability criteria so manufacturers and test laboratories can demonstrate that internal non‑metallic toecaps provide adequate protection against mechanical impact and compression before being incorporated into safety or protective footwear.

Key Topics and Requirements

• Scope and intent: Applies to internal non‑metallic toecaps (not external toecaps) intended to protect against impact and compression.
• Two toecap types: Type A and Type B are defined to cover different footwear constructions.
• Finishing: Toecaps must be free of surface marks, burrs, sharp edges, splitting or delamination.
• Dimensions:
  • Minimum internal length specified by toecap size (e.g., smaller sizes have lower minimums; the standard includes a sizing table).
  • If a flange is present, the inside width of the flange must not exceed 15 mm.
• Impact resistance:
  • Tested at energy levels of (100 ± 2) J for protective footwear and (200 ± 4) J for safety footwear.
  • Minimum clearance under the toecap at impact is specified per size and type; toecaps must not develop sharp edges, cracks that transmit light, or delaminate.
• Compression resistance:
  • Compression loads of (10 ± 0.1) kN (protective) or (15 ± 0.15) kN (safety) with minimum clearance requirements analogous to impact testing.
• Environmental stability:
  • Requirements after treatments (high/low temperature, fuel oil exposure) to ensure impact resistance is retained.
• Test methods: Detailed procedures for determining internal length, flange width, impact and compression resistance, and post‑treatment testing (see Clauses 5.x).
• Measurement uncertainty: The standard requires estimating uncertainty of measurement using established methods (e.g., ISO statistical guides).

Applications and Users

Who uses ISO 22568-2:2019:

• Toecap manufacturers - to validate design and demonstrate compliance.
• Footwear manufacturers - to select compliant components for PPE footwear (ISO 20345/20346).
• Testing laboratories and certification bodies - to perform standardized impact, compression and environmental tests.
• Procurement and safety managers - to specify compliant footwear components and verify supplier claims.

Practical benefits:

• Ensures consistent protection levels across non‑metallic toecaps.
• Facilitates component-level testing before final assembly.
• Supports regulatory and procurement requirements for workplace safety.
