EN ISO 16321-3:2022/A1:2026 is a CEN amendment to the European adoption of ISO 16321-3 for eye and face protection for occupational use. It updates the mesh-protector requirement in clause 4.3, which is the part that checks the number of apertures in mesh face shields, goggles and mesh spectacles. Manufacturers, test laboratories, conformity assessment bodies and buyers use it when specifying or checking mesh eye and face protection.

What does EN ISO 16321-3:2022/A1:2026 specify?

EN ISO 16321-3:2022/A1:2026 specifies a targeted change to Part 3 of the eye and face protection series. The amendment replaces the first paragraph of clause 4.3, so users apply the revised aperture-count requirement instead of the earlier wording.

The document is therefore short and focused. Its practical job is to refine how mesh protectors are judged during testing, rather than to restate the whole of Part 3.

What are the key requirements of EN ISO 16321-3:2022/A1:2026?

EN ISO 16321-3:2022/A1:2026 changes the way the number of apertures in mesh protectors is verified. The key point is that the requirement now distinguishes between product types and ties the check to a named test method.

• Clause 4.3 is the only technical point changed by the amendment. In practice, users should read the revised paragraph as replacing the earlier aperture-count rule.
• Mesh face shields and goggles are treated together in the amended text. For these products, the test counts whole apertures within a square aperture over a defined mesh area, so laboratories need a consistent counting window and sample size.
• Mesh spectacles are treated separately from mesh face shields and goggles. This matters because the standard applies a different aperture-count condition to spectacles, so product classification affects acceptance.
• The amendment uses ISO 18526-3:2020, 11.1 as the test reference. That means the aperture check is not improvised by the tester - the counting is linked to a specific laboratory method.
• The requirement is about the number of whole apertures per unit area of mesh. In practice, manufacturers need to control the mesh pattern, and buyers need to specify the correct product type before testing starts.
• The wording in the amendment is procedural as well as technical. It tells the reader what to count, how to sample the mesh, and which test clause to follow.
• Because the same clause now separates product groups, quality teams should make sure drawings, product descriptions and test reports identify whether the item is a mesh face shield, goggle or spectacle.

What terms does EN ISO 16321-3:2022/A1:2026 define?

EN ISO 16321-3:2022/A1:2026 uses a small set of product and test terms that matter for applying clause 4.3.

• Mesh protectors - eye and face protectors made from a mesh structure that is assessed by aperture count.
• Mesh face shields - mesh protectors intended to cover the face, with the amended requirement grouped together with goggles.
• Goggles - close-fitting eye and face protection covered by the same aperture-count rule as mesh face shields.
• Mesh spectacles - spectacle-style mesh protectors with their own aperture-count condition in the amended clause.
• Square aperture - the square counting area used during testing to assess the mesh openings.
• Whole apertures - complete mesh openings that are counted within the test area.
• ISO 18526-3:2020, 11.1 - the referenced test clause used to perform the aperture-number check.

Who uses EN ISO 16321-3:2022/A1:2026?

EN ISO 16321-3:2022/A1:2026 is used by people who design, test, approve or buy occupational eye and face protection. That includes manufacturers of mesh protectors, test and certification laboratories, quality managers, and purchasing teams.

It is also relevant to occupational safety specialists and PPE reviewers who need to specify the right product type and the right test method. In practice, they use it to confirm that mesh face shields, goggles and spectacles are checked against the same revised framework in clause 4.3.

What changed in EN ISO 16321-3:2022/A1:2026 from the previous edition?

EN ISO 16321-3:2022/A1:2026 replaces the specification of the number of apertures in mesh protectors in clause 4.3. The amendment introduces separate wording for mesh face shields and goggles on one side, and mesh spectacles on the other, with the test linked to ISO 18526-3:2020, 11.1.

Which standards are used with EN ISO 16321-3:2022/A1:2026?

The amendment names ISO 18526-3:2020, 11.1 as the test reference for checking the number of apertures in mesh protectors. That standard contributes the laboratory method used to carry out the aperture-count test.

EN ISO 16321-3:2022 is the Part 3 document being amended here. In practice, users read this amendment together with the base Part 3 requirement it updates.

What does the EN ISO 16321-3:2022/A1:2026 document contain?

EN ISO 16321-3:2022/A1:2026 contains the amendment notice and the replacement text for clause 4.3. The operative content is a revised paragraph that separates mesh face shields and goggles from mesh spectacles and directs the reader to ISO 18526-3:2020, 11.1 for testing.

The document is used for product specification, laboratory verification and conformity assessment. Its purpose is to make the aperture-count check for mesh protectors clearer and product-specific.
