The Luminous Afterglow Performance Tester is a precision instrument designed to evaluate the afterglow characteristics of textiles, including fibers, yarns, fabrics, and powders. It measures the brightness and decay time after excitation, providing quantitative data for luminescent materials. The system features automated measurement, data recording, and sample switching for efficient, repeatable testing.
The instrument is widely used in:
Textile R&D: Evaluating luminescent fibers, yarns, and glow-in-the-dark fabrics.
Quality Control: Ensuring consistent afterglow performance in production batches.
Specialty Materials: Testing photoluminescent coatings, powders, and textiles.
Safety Textiles: Evaluating visibility features in reflective and emergency fabrics.
Educational and Research Institutions: Studying luminescence properties in textiles and materials science.
Chinese Standards:
GB/T 43716-2024: Textiles – Test Method for Luminous Afterglow Performance – Photometer Method
International Standards (Expanded Reference):
ISO 17398: Photoluminescent materials – Determination of afterglow properties
ASTM E2072: Standard Test Method for Photoluminescence of Materials
EN 1838: Lighting Applications – Emergency lighting – Luminance and duration requirements
BS EN 14256: Photoluminescent coatings and textiles – Afterglow measurement
IEC 62721: Photoluminescent performance testing for materials and coatings
Instrument Features
Automatic measurement and data recording: Records brightness values over the set test duration with software support.
Fully enclosed test chamber: Reduces interference from external light sources for accurate measurements.
Sample automation: Automatically switches among 3 sample positions for high-throughput testing.
High-precision sensors: Imported brightness and illuminance sensors with fast sampling speed and high accuracy.
Wide applicability: Suitable for fibers, yarns, fabrics, and powders.
User-friendly interface: Integrated computer system with printer for instant data output.

1 main unit
1 Lenovo integrated computer
1 Lenovo laser printer
3 sample clamps
1 excitation light source
Secure samples in the clamps within the enclosed chamber.
Turn on the excitation light source and irradiate the sample to saturation.
Remove the excitation light and start the measurement via software.
The instrument automatically records brightness values and decay times.
After completion, save or print the data for analysis.
Clean the chamber and clamps regularly to prevent dust accumulation.
Periodically calibrate the brightness meter and illuminometer to maintain accuracy.
