UV Standard 801
Textiles are intrinsically suited for use as UV protection, as they are able to offer particularly good protection against intense radiation from the sun if suitable materials and constructions are used.
UV-protection factors (UPF = Ultra Violet Protection Factor) can be achieved which are far above those of the strongest sunscreens (sun blocks).
In order to provide consumers with a reliable UPF, the specific requirements which a sunscreen textile will be subjected to in use need to be taken into account, however.
The Hohenstein Institute is a founder member of the International Test Association for Applied Protection against UV Radiation responsible for developing the UV Standard 801. Unlike other international test methods such as the AS/NZS (Australasian Standard 4399:1996), EN 13758-1:2007-03 (European Standard) and AATCC TM 183-2000 (American Standard), under the UV Standard 801 aspects such as the stretching of the textile, and the wetting and ageing of the material are taken into consideration.
As a result of these conditions of use, the protection factor of clothing or shade textiles such as awnings, beach shelters or sunshades can be reduced drastically. In order to avoid adverse effects for the wearer, this must also be reflected in the UPF factor given.
Based on our measurements, you can optimise the UV-protection factor of your products and identify your products with the well-known UV Standard 801 label. You can find an overview of products certified according to UV Standard 801 together with manufacturers here.
