The Absolute Method Retro-Reflective Coefficient Tester is a precision instrument designed to evaluate the retro-reflective performance of high-visibility safety materials under both dry and simulated rain conditions. It accurately measures the retro-reflection coefficient of sample surfaces, making it suitable for occupational high-visibility warning garments and other visibility safety apparel to ensure personnel safety and compliance with national standards.
Standards
The system supports compliance with the following standards:
GB 20653-2020 – Occupational High-Visibility Warning Clothing, Appendices C.4.1 (Absolute Method) and D
GB/T 28468-2012 – School Traffic Safety Reflective Uniforms
ASTM E808 – Standard Guide for Description of Retro-Reflective Materials (Reference)
ASTM E810 – Standard Test Method for Retro-Reflective Coefficient of Sheeting Materials (Reference)
DIN 67520 – Minimum Luminance Requirements for Traffic Safety Reflective Materials (Reference)
