紫外線指數是量度太陽紫外線到達地球表面的强度, 它直接影嚮人類皮膚. 皮膚破壞程度大致根據紅斑光譜. 國際組織 CIE (International Commission on Illumination) 採用這光譜去代表人平均皮膚受太陽紫外線反應.

Definition 　 The Global Solar UV Index(UVI) describes the level of solar UV radiation at the Earth’s surface. The values of the index range from zero upward? the higher the index value, the greater the potential for damage to the skin and eye, and the less time it takes for harm to occur. 　 UV Index and Dangers of UV Exposure UV INDEX 0 1 2 3 4 5 6 7 8 9 10 +11 EPA* MINIMAL LOW MODERATE HIGH VERY HIGH CANADA LOW MODERATE HIGH EXTREME KOREA MINIMAL LOW MODERATE HIGH VERY HIGH WHO LOW MODERATE HIGH VERY HIGH EXTREME * EPA : U.S. Environmental Protection Agency * WHO : The World Health Organization 　 　 Formulation for UV Index   The Global Solar UV Index(UVI) is formulated using the international Commission on Illumination (CIE) reference action spectrum for UV-induced erythema on the human skin(IS) 17166:1999/CIE007/E-1998). It is measure of the UV radiation that is relevant to and defined for a horizontal surface. 　 　 　 Sun Protection Factor   Sun Protection Factor (SPF) is a scale for rating the level of sunburn protection against UV radiation in sunscreen products. The higher the SPF, the more sunburn protection it provides. Sunscreen SPF ratings are determined by testing sun-screens on the skin of human volunteers in accordance with Australian Standard AS2604: 1998. 　 Recommended SPF by UV Index UV INDEX 0 1 2 3 4 5 6 7 8 9 10 11 Dangers of Exposure MINIMAL LOW MODERATE HIGH VERY HIGH SPF Under 4 4 ~ 7 7 ~ 9 9 ~ 12 12 ~ 15 　 　 Protection Factor of UVA     Protection Factor of UVA(PFA) value of a test sample is defined as the arithmetic mean of each subject’s PFA values obtained from the above equation. MPPD : Persistent Pigment darkening Dose. 　 PFA value PA(Protection grade of UVA) UVA protectio effect 2 or more but less than 4 PA+ effective 4 or more but less than 8 PA++ very effective 8 or more PA+++ highly effectiv
