Overview

EN ISO 22568-4:2021 specifies requirements and test methods for non‑metallic perforation resistant inserts used as components of PPE footwear. It defines how to assess mechanical perforation resistance and related performance attributes so manufacturers, test laboratories and procurement bodies can verify that inserts intended for use in safety, protective or occupational footwear perform reliably when exposed to mechanical and environmental stresses.

Key topics and requirements

Perforation resistance: Two test methods are defined - Method PL (conical nail 4.5 mm diameter) and Method PS (conical nail 3.0 mm diameter). These methods evaluate an insert’s ability to resist penetration by a sharp object.

Performance thresholds: The 2021 edition introduced updated type names (PL, PS), requirements addressing the “tent effect” (separation between layers during testing) and a minimum force requirement (950 N) for certain criteria.

Durability and flexibility: Tests for flexing resistance assess the insert’s ability to withstand repeated bending in service without failure.

Environmental and ageing stability: Procedures simulate high temperature, acid/alkali sweat, and fuel oil exposure to evaluate whether resistance is maintained under critical environmental conditions.

Electrical resistance: Measurement methods determine whether inserts affect the electrical properties of footwear.

Marking and documentation: Requirements for test reports and product marking ensure traceability and correct specification of insert type and performance.

Normative structure: Annexes provide the detailed test set‑ups for Method PL and Method PS; normative references include ISO 20344 (footwear test methods) and ISO 105‑E04 (colour fastness to perspiration).

Applications and users

Footwear component and PPE footwear manufacturers verifying insert performance before assembly.

Independent testing laboratories conducting conformity and type testing.

Certification bodies and compliance assessors for safety footwear standards.

Occupational safety managers, procurement officers and specifiers who require documented perforation resistance in PPE footwear for workplaces (construction, manufacturing, utilities, emergency services).

Practical uses:

Pre‑qualification of non‑metallic inserts as alternatives to metal midsoles.

Demonstrating compliance with safety footwear programs (ISO 20345 / ISO 20346 / ISO 20347).

Ensuring product consistency after exposure to flexing, chemicals or temperature.
