Test criteria

UPF allows an evaluation of UV protection provided by textiles. It considers the spectral composition of sunlight and human skin sensitivities.

Testing the Ultraviolet Protection Factor (UPF) of textiles can be assessed according to the the American Standard (AATCC TM 183), Australian/New Zealand Standard (AS/NZS 4399) and/or European Norm (DIN EN 13758-1).

These standards describe UV protective properties of textiles in new and unused state. Classifications depend on the level of UPF detected: "Minimum" (UPF 15), "Good" (UPF 30) or "Excellent" (UPF 50, 50+). 

FACTSHEET: TEXTILE UV PROTECTION

Testing:

The Australian/New Zealand Standard (AS/NZS) is based on the solar spectrum of Melbourne, Australia.

The whole standard is applicable for clothing. Advertisement according to the standard refers to the material testing according to appendix A and point 5. Additionally, the manufacturer is responsible for the compliance with all other requirements (point 4. Body Coverage and point 6. Marking). These other requirements are not subject to the test program of the Hohenstein Quality Label.

The textiles are tested in dry and new condition. The UV-protective properties of the tested fabric are described with "Minimum" (UPF 15), "Good" (UPF 30) or "Excellent" (UPF 50 and UPF 50+ respectively) in accordance with the resultant UPF value.

The determination of the UPF of the submitted material in unused, dry condition is approved by the authorities as evidence of UV protection.

Validity period:

1 year

Materials for:

  • clothing textiles
  • shading textiles, e.g. parasols, awnings, roller blinds etc. (modified scope)
  • films (modified scope)

The textiles are tested in dry and new condition. The UV-protective properties of the tested fabric are described with "Minimum" (UPF 15), "Good" (UPF 30) or "Excellent" (UPF 50 and UPF 50+ respectively) in accordance with the resultant UPF value.

  • shading textiles, e.g. parasols, awnings, roller blinds etc. (modified scope)
  • films (modified scope)

Description:

With this standard, the Ultraviolet Protection Factor (UPF) of textile materials or similar (e.g. films) is determined in dry and new condition without the strain in usage.

The UPF allows an assessment of the UV protection offered by textiles under consideration of the spectral composition of the sunlight and the skin sensitivity of human beings.

Testing:

The European Standard (DIN EN) is based on the solar spectrum of Albuquerque, New Mexico (USA), which is approximate to the solar spectrum of South Europe.

The standard is primary applicable for clothing. Advertisement according to the standard only refers to material testing. The textiles are tested in dry and new condition. In accordance with the resultant UPF value, the UV-protective properties of the tested fabric are assessed according to the classification based on AS/NZS 4399, point 5. This means "Minimum" (UPF 15), "Good" (UPF 30) or "Excellent" (UPF 50 and UPF 50+ respectively)

DIN EN 13758-2 is not subject to the test program of the Hohenstein Quality Label. Therefore, these requirements are not taken in consideration for granting the Hohenstein Quality Label. The manufacturer is responsible for seeing that the design meets all consumer protective requirements.

The determination of the UPF of the submitted material in unused, dry condition is approved by the authorities as evidence of UV protection.

Validity period:

1 year

Materials for:

  • clothing textiles
  • shading textiles, e.g. parasols, awnings, roller blinds etc. (modified scope)
  • films (modified scope)
