UPF TestIng | Ultraviolet Protection Factor Testing for Clothing And Fabrics

Ultraviolet Protection Factor (UPF) Test Includes First 2 Samples

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 as an option, which details the statistical properties of the measurements of your samples, as well as equipment used in the testing. You may optionally launder the article(s) prior to testing, please include that as a note on the Material Test Form, along with any other conditioning, location specifics and whether to include wet testing. Typical turnaround is cited as five (5) business days after we receive the prepared samples to test.

Description

What is UPF Testing?
Ultraviolet Protection Factor (UPF) is a weighted spectral transmission value which can quantify the amount of skin-effective UV radiation that is transmitted through materials.

15-24 is good25-39 is very good40 or higher is excellent
50+ is the maximum factor according to the standards.

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%.
