Overview
EN ISO 20344:2021 (ISO 20344:2021) specifies standardized test methods for footwear designed as personal protective equipment (PPE). Adopted as the European standard EN ISO 20344:2021 and replacing the 2011/2012 edition, it defines the sampling, conditioning, test procedures and reporting required to evaluate protective footwear performance consistently across laboratories and manufacturers.
Key topics and technical requirements
This standard focuses on practical, laboratory-level methods rather than performance limits (those are in companion product standards). Major technical subjects covered include:
- General testing parameters: sampling, conditioning of test specimens, prerequisites for procedures and required contents of the test report.
- Whole-footwear tests: ergonomic feature checks, upper/outsole and sole interlayer bond strength, dimensions of toecaps and perforation-resistant inserts.
- Toecap performance: determination of impact resistance, compression resistance, and behaviour under thermal/chemical exposure.
- Perforation resistance: methods for footwear with metallic and non-metallic inserts, including dimensions, puncture tests, flex resistance and thermal/chemical behaviour of inserts.
- Other functional tests: leak proofness, electrical resistance, slip resistance, and insulation properties.
- Test reporting: standardized content and format to ensure reproducibility and traceability of results.
(Note: ISO 20344 defines how to test - performance criteria and classification typically appear in product standards such as ISO 20345/20346/20347.)
Practical applications and target users
ISO 20344 is used by stakeholders involved in the design, production, testing and regulation of protective footwear:
- Manufacturers and designers - to validate prototypes, production methods and material choices against recognized test procedures.
- Independent testing laboratories and certification bodies - to perform accredited, reproducible tests needed for compliance and CE/market approval.
- Quality assurance teams and procurement specialists - to verify supplier claims and ensure product consistency.
- Regulators and occupational safety professionals - to interpret test data when setting workplace PPE requirements or specifying approved footwear.
Using ISO 20344-aligned methods helps reduce disputes, improves international market access, and supports reliable product declarations.
