The Ultraviolet Radiation transmitted through a fabric to the skin is measured and given a rating of 15 (good protection), 30 (very good protection), 50+ (excellent protection).
Bisley Workwear garments that comply to this standard provide protection against ultraviolet radiation transmitted from the sun, tested in accordance with Australian Standard AS/NZS 4399:1996. The sun protection rating shown is rated at: Good Protection (UPF 15, 20), Very Good Protection (UPF 25, 30, 35), or Excellent Protection (40, 45, 50, 50+). Only areas of the body which are covered by material are protected. When the most effective sun protection is required, we recommend a garment which covers the full arm and leg area and has a sun protection rating of UPF 50+.
