EN ISO 16321-3:2022/FprA1 - Overview
Title: Eye and face protection for occupational use - Part 3: Additional requirements for mesh protectors - Amendment 1 (ISO 16321-3:2021/DAM 1:2025)
Organization: CEN / ISO (ISO/TC 94/SC 6)
This amendment updates the mesh-specific requirements in the ISO 16321-3 series for occupational eye and face protection. It revises clause 4.3 - Number of apertures in mesh protectors, specifying minimum whole-aperture counts for mesh face shields, goggles and spectacles when tested according to ISO 18526-3:2020, 11.1. The document appears circulated as a draft amendment for comment and approval.
Key topics and technical requirements
- Scope: Additional requirements for mesh protectors used as occupational eye and face PPE (mesh face shields, mesh goggles, mesh spectacles).
- Main technical change: replacement of the first paragraph of clause 4.3 to set quantitative aperture-density requirements:
- Mesh face shields and goggles: minimum 15 whole apertures per cm² when using a square aperture covering at least 90 apertures (test per ISO 18526-3:2020, 11.1).
- Mesh spectacles: minimum 50 whole apertures per cm² when using a square aperture covering at least 150 apertures (test per ISO 18526-3:2020, 11.1).
- Test reference: all aperture-count requirements are tied to the ISO 18526-3:2020 test method (sample area and counting procedure in clause 11.1).
- Administrative note: the amendment replaces the prior specification for aperture counts in the base Part 3 standard.
Practical applications and users
This amendment is directly relevant for:
- PPE manufacturers and designers producing mesh face shields, mesh goggles and mesh spectacles - to ensure product designs meet standardized aperture-density requirements.
- Testing and certification laboratories performing ISO 18526-3 aperture-count tests and conformity assessments.
- Occupational safety managers, procurement teams and regulators specifying compliant mesh eye/face protection for industries such as metalworking, forestry, and agricultural operations where mesh guards are used.
- Standards bodies and compliance consultants updating technical documentation and conformity criteria.
Benefits:
- Provides clear, measurable criteria (apertures per cm²) for assessing mesh protector performance.
- Improves consistency in testing and certification of mesh-based eye and face protection.

- ISO 16321 series (Eye and face protection for occupational use) - Part 3 is the mesh-specific part.
- ISO 18526-3:2020 - referenced test method for aperture counting (clause 11.1).
