UPF TestIng | Ultraviolet Protection Factor Testing for Clothing And Fabrics

Ultraviolet Protection Factor (UPF) Test

Solar Light performs accurate UPF testing for clothing and fabrics to all major worldwide standards: AATCC 183, BS EN 13758-1, GBT18830-2009, and NZS 4399 – please advise which you need, and we will perform the testing accordingly. We can include a UPF Certification Report optionally which details the specific measurements of your samples, as well as equipment used in the testing, and all relevant data points. (Please note: Some of the standards require laundering the article prior to testing.) Typical turnaround is only a few days after we receive the prepared samples to test.

UPF Testing is $250.00 for the first two samples, and $75.00 for each additional sample. A UPF Certificate Report covering all samples tested is optional, for $75.00 additional. Please select from the Testing Options below. Preferred sample size is 5×5 inches (or 13 x 13 cm). All testing is performed dry, and any samples sent should be pre-laundered if the UPF standard selected calls for it.

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.
