CIE 186:2010 PDF Download

The CIE 186:2010 standard was developed by the CIE Technical Committee TC 6-24 to provide guidance and regulations on tests for UV-A protection. The committee was formed in 1992 due to the importance of addressing the harmful effects of UV-A radiation and the lack of existing standards in this area. Initially, the committee identified one in vivo method, Persistent Pigment Darkening, and several in vitro methods for testing UV-A protection. However, a consensus could not be reached at that time.

Over the years, the development of methods to assess UV-A protection continued, with a particular focus on in vitro methods. Advances in computer-aided calculations, referred to as in silico, also contributed to the understanding and evaluation of sunscreen performance. Instead of striving for a consensus on sunscreen testing, the objective of the reactivated TC 6-24 has been modified to provide a comprehensive overview of the UV-A methods under discussion in the form of a Technical Report.

The CIE 186:2010 standard begins with an introduction to the general principles of UV protection and an overview of UV-A and broad-spectrum UV filters. It then proceeds to describe and assess various methods used for testing UV-A protection, including in vivo, ex vivo, in vitro, and in silico approaches. The standard aims to provide a comprehensive understanding of UV-A protection and sunscreens, facilitating informed decision-making in this field.
