In October 2022, CEN officially released a new standard for sunglasses, EN ISO 12312-1:2022. The version has been updated to 2022, replacing the old version of EN ISO 12312-1:2013/A1:2015

Standard implementation date: January 31, 2023

Regulatory requirements and precautions: Currently, the coordinated standard for sunglasses in the EU PPE regulation (EU 2016/425) is still the old version of EN ISO 12312-1:2013/A1:2015. When will the new version of the coordinated standard for sunglasses be adopted (i.e. EN ISO 12312-1:2022 has not yet been officially adopted by EU regulations), and the EU has not provided a specific timetable.


Compared to the old version of the standard, the main changes in the new version are as follows:

● Requirements for adding electrochromic lenses;

Replace the inspection method for local refractive power changes with the inspection method for observing regular grid images through lenses (ISO 18526-1:20206.3);

● Introduction of activation of Photochromic lens at 5 ° C and 35 ° C as optional information;

Extend side protection to Category 4 children's sunglasses;

Introduce seven headforms, three Type 1 and three Type 2, plus one child headform according to ISO 18526-4:2020. Each type comes in three sizes - small, medium, and large. For sunglasses, the use of these test head models typically involves different pupil spacing. For example, the pupil spacing for Type 1 is 60, 64, or 68 millimeters;

Update the uniformity requirements for visible light transmittance within a single area, reduce the measurement area to a diameter of 30mm, and increase the limit to 15% (the 20% limit for Class 4 filters remains unchanged).

The new version of the sunglasses standard EN ISO 12312-1:2022 will have a certain impact on the test results due to changes in the requirements of the head mold parameters and testing items.
