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.
Application
The tester is suitable for a wide range of applications:
Traffic Safety Materials: Assessing retro-reflective performance of road and railway signs, traffic safety uniforms, and school uniforms for visibility compliance.
Occupational Safety Garments: Evaluating high-visibility protective clothing worn by various professionals for safe warning and visibility.
Vehicle Inspection: Measuring reflective markings on trucks and commercial vehicles.
Quality Control: Testing reflective vests, license plates, and other materials for retro-reflective compliance.
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)
