UPF50+ Rating On A Product
What does UPF50+ mean?
UPF stands for ultraviolet protection factor and is the sun protective rating measure for fabrics. This rating indicates how well the material blocks ultraviolet radiation from the sun.
UPF50+ means that only up to 1/50th (2% or less of the ultraviolet radiation was able to penetrate through the fabric that was tested).
What is the difference between SPF and UPF?
SPF stands for Sun Protection Factor, this is the rating given to sunscreens and other sun-protective skin products. It measures the amount of time it takes for sun-exposed skin to redden and burn. SPF is for creams and cosmetics.
UPF measures the amount of UV radiation that penetrates a fabric and reaches the skin. This will depend on the tightness of the weave, the weight of the fabric, type of fiber, color and amount of skin covered, all of these factors affect the amount of protection a fabric provides. UPF is used to rate clothing and fabrics.
The Australian/New Zealand standard for sun protective clothing has three protection classifications depending on the amount of ultraviolet radiation blocked.
| UPF Rating | Classification |
| 15 - 20 | Good UV Protection |
| 25 - 35 | Very Good UV Protection |
| 40 - 50, 50+ | Excellent UV Protecton |
Fabrics which has been awarded a UPF 50+ rating by the Australian Government are considered to provide excellent sun protection.
