Revision of ISO 24443 – Determination of Sunscreen UVA Photoprotection In-vitro by Helioscreen

6 September 2022

The ISO 24443 standard specifies an in vitro procedure to characterize the UVA protection of sunscreen products (in vitro UVAPF and Critical Wavelength). Initially published in 2012, the second
edition has been technically revised in 2021 (with a corrected version in 2022).
