This International Standard specifies an in vitro procedure to characterize the UVA protection of sunscreen
products. Specifications are given to enable determination of the spectral absorbance characteristics of UVA
protection in a reproducible manner.
In order to determine relevant UVA protection parameters, the method has been created to provide a UV spectral
absorbance curve from which a number of calculations and evaluations can be undertaken. Results from
this measurement procedure can be used for other computations, as required by local regulatory authorities.
These include calculation of the Ultraviolet-A protection factor (UVAPF) [correlating with in vivo UVAPF
from the persistent pigment darkening (PPD) testing procedure], critical wavelength and UVA absorbance
proportionality. These computations are optional and relate to local sunscreen product labelling requirements.
This method relies on the use of in vivo SPF results for scaling the UV absorbance curve.
This International Standard is not applicable to powder products such as pressed powder and loose powder products.
