Solar radiation is essential for human health. For example, the body needs it to form vitamin D (used in bone formation). At the same time, the ultraviolet rays from sunlight present great potential for stress to the skin.
Dermatologists have seen a significant increase in skin cancer, worldwide. In the U.S., skin cancer is diagnosed more than all the other cancers combined.
Dermatologists warn against extended sun exposure. Children, whose skin is still very thin and without the full protective mechanisms that develop around age 15, are at higher risk. People who work outdoors for extended time periods (ie. construction workers, road workers or gardeners) require optimized workwear. Clothing and shading textiles are especially suited to protection.
Textiles with optimized materials and constructions are ideal for UV protection that far exceeds the maximum UV protection factors (UPF) of the strongest sunblock cream.
Customers cannot assess the UV protection factor of a material just by sight or touch. UV protection also varies with skin type and sun intensity. Based on standardized measurement procedures and expert testing we assign comparable and reliable values for the UV protection of garments or shades.
We test according to various standards and award the Hohenstein Quality Label.
- Australia-New Zealand standard (AS/NZS 4399): new, unstretched and dry textiles tested with the solar spectrum is Melbourne, Australia, on the 1st of January
- European Standard (DIN EN 13758-1): new, unstretched and dry textiles tested with the solar spectrum of Albuquerque, New Mexico.
- American Standard (AATCC TM 183): textiles in new condition tested with the solar spectrum of Albuquerque, New Mexico.
For the UV STANDARD 801, we consider important aspects of use, including stretching of the textile, wetting of clothing, weathering of shading textiles, aging by certain abrasion and washing cycles and many more. We also assume maximum radiation intensity with the solar spectrum in Melbourne, Australia, on the 1st of January (peak of the Australian summer). The UV STANDARD 801 label tells your customers that their textiles have been measured to the strictest standards and offer reliable UPFs.
