Without the sun there is no life. However, it also has its downsides, with ultraviolet (UV) rays that can damage the skin. Sun cream and sun blocker do provide some protection against UV rays, but they do not replace other precautions like clothing or sunshades. With the right materials and designs, these safeguards provide much more effective UV protection than the strongest sun creams.
Hohenstein is a founding member of the International Test Association for Applied Protection against UV Radiation. It was involved in the launch of the UV STANDARD 801, a certification and product label that offers reliable UV protection through textiles thanks to its use-based concept. One crucial benefit to consumers is that, unlike other international standards, the standard also covers aspects such as how the textile stretches when worn, the dampness of the material (for example, caused by swimming or sweating) and the unavoidable aging of textile products due to wear, weather and cleaning.
To determine a reliable Ultra Violet Protection Factor (UPF) for the consumer, every factor that plays a role in the use of sunshade textiles must be taken into account. Measurements of UV protection that assess the tested goods only in their as-new condition are therefore less meaningful. The measurement of the UV protection factor in accordance with the UV STANDARD 801 uses the most stringent criteria based on a simulation of the most realistic conditions possible. It includes:
- A worst-case scenario (maximum UV ray intensity based on the solar spectrum used by Australian/New Zealand standards and the most sensitive skin type)
- Validated measurement procedures for simulating typical usage conditions (soaked clothing, weathering on sunshade textiles, an aging process based on rubbing and wash cycles and stretching of the material)
The determined UPF is used as a multiplier for the natural protection time of the skin type in question and indicates how much longer the textile lets you stay out in the sun while effectively protecting your skin from damage. The following UV protection factors (UPF) can be achieved in accordance with the UV STANDARD 801 and marked on the label: e.g. 2, 5, 10, 15, 20, 30, 40, 60, 80.
