What is UPF Testing?
Ultraviolet Protection Factor (UPF) is a spectral transmission analysis which can quantify exactly how much UV radiation permeates materials. The UPF Rating Scale is between 15 and 50:
15-24 is good
25-39 is very good
40 or higher is excellent
For example, a shirt with a UPF rating of 15 means that 1/15th of the sun’s UV radiation can reach the wearer’s skin, while a shirt with a UPF rating of 50 means that only 1/50th of the sun’s UV radiation can reach the wearer’s skin. Another way to perceive this rating is a UPF of 20 (allowing 1/20th of UV through) is equivalent to blocking 95%. A UPF of 40 blocks 97.5% and a UPF of 50 blocks 98%.
UPF ratings are becoming more prevalent in the civilian clothing industry as people seek alternatives to sunscreen lotions, though it should be noted that UPF gauges a fabric’s effectiveness against both UVA and UVB light, while sunscreen’s SPF number pertains only to a sunscreen’s effectiveness against UVB rays (the sunburn-causing segment of the ultraviolet spectrum.) High-risk groups with an elevated need for high UPF-rated clothing include fair skinned, sun-sensitive people, children, and people who spend extended time at high elevation, equatorial regions, and near reflective surfaces such as snow and water.
