Fabric UV resistance tester
The Fabric UV Resistance Tester is designed to simulate solar UV radiation and evaluate the ultraviolet protection performance of textiles, sun-protection products, and cosmetics. The instrument replaces in-vivo testing, providing accurate SPF measurement, UVA/UVB analysis, and critical wavelength evaluation. It combines a stable UV-visible light source, spectrophotometric detection, and powerful data analysis software, offering fast, economical, and reproducible testing.
Application
Assessing SPF value, UVA/UVB absorption, and UV protection of fabrics, sunscreens, and cosmetics.
Research & development of UV protective clothing and sun-care products.
Quality control in textile manufacturing, cosmetics production, and certification labs.
Replaces human body (In-Vivo) testing for cost-effective and standardized UV evaluation.
Standards
AATCC 183 – Determination of SPF for textiles
AS/NZS 4399 – Sun Protective Clothing Standard
ISO 24443 – In vitro determination of sunscreen UVA protection
Colipa 2011 – European sunscreen testing standard
FDA – Sun protection product guidance
Other international UV protection standards
