UV Protection Factor (UPF) certification for the real world.

Hohenstein is a founding member of the International Test Association for Applied Protection against UV Radiation, which launched UV STANDARD 801, a certification and product label for textiles that offer reliable UV protection.

Unlike other standards, UV STANDARD 801 considers 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 washing. Measurements of UV protection that assess goods only in their new condition are less meaningful.

What makes the UV STANDARD 801 different?

To determine a reliable Ultraviolet Protection Factor (UPF), every factor playing a role in the use of textiles must be considered.

UV STANDARD 801 uses the most stringent criteria based on a simulation of realistic conditions:

  • A worst-case scenario (maximum UV ray intensity based on the Australian/New Zealand solar spectrum and the most sensitive skin type)
  • Validated measurement procedures for simulating typical usage conditions (soaked clothing, weathered sunshade material, stretched material, aged textiles based on rubbing and wash cycles)

Comparison of international standards.

Ultraviolet Protection Factor (UPF)

The determined UPF is used as a multiplier for the natural protection time, based on skin type, and indicates how long the textile lets you stay out in the sun while effectively protecting your skin from damage. The following UPF can be achieved in accordance with the UV STANDARD 801 and marked on the label: e.g. 10, 15, 20, 30, 40, 60, 80.
