It’s summertime! How to measure textile materials for their UV protection factor ?
Resistance to ultraviolet (UV) penetration is measured in a very objective manner. The principle is conceptually quite simple: a light source generating UV radiation (UVA; UVB) is used. The textile material is exposed to this radiation, and a photoreceptor is placed on the back of the textile to measure the amount of UV that passes through the textile.
