UV protection
Use of EN 13758-2 garments
International research has shown that prolonged exposure to the sun increases the risk of sunburn, skin damage, premature ageing and even skin cancer. Clothing is one of the most effective forms of protection. The level of UV protection varies depending on several factors, including fabric thickness, weave, and the overall garment design.
To prevent sunburn, long-sleeved garments complying with EN 13758-2 can be worn. These garments must have a minimum Ultraviolet Protection Factor (UPF) of 40, tested according to EN 13758-1. In practice, this means that only a small fraction of UV radiation penetrates the fabric and reaches the skin.
How UPF ratings work
UPF indicates how much UV radiation a fabric blocks. The higher the rating, the stronger the protection. For example, UPF 50+ means that the garment allows only 1/50th of the sun’s rays to pass through, blocking over 98% of UV radiation.
| UPF rating | Protection level | UV radiation blocked (%) |
|---|---|---|
| 15 - 24 | Good | 93.9 - 95.8% |
| 25 - 39 | Very good | 96 - 97.4% |
| 40 - 50 | Excellent | 97.5 - 98%+ |
UV protective clothing shields against UVA and UVB
These rays affect the skin differently, but both can cause serious harm.
UVA
About 95% of the sun's UV rays that reach the earth's surface are long-wave ultraviolet A rays. These rays have a lower amount of energy, but penetrate deep into the skin. They are linked to skin damage and aging.
UVB
The other 5% are short-wave ultraviolet B rays. They mainly reach the outer layer of the skin, but have a high amount of energy. Among others, these rays increase the risk of skin cancer.
Correct use and maintenance of EN 13758-2 clothing
Only the covered body parts are protected.
Protection may be reduced if the garment is stretched, wet, or worn out.
