System Overview
Controlled UV Exposure for Laminated Glass Evaluation
Technical Architecture
Core System Components
- Power supply
- UV lamp
- Rotating sample drum
- Motor and reduction drive
- Control circuit
Test Principle
Evaluate Glass Before and After UV Exposure
Initial Evaluation
The specimen is first evaluated for light transmittance before irradiation where required.
Controlled Exposure
The specimen is exposed inside the NF-5 for the specified test duration and temperature.
Post-Exposure Review
After irradiation, the specimen can be evaluated again for visible discoloration and reduction in light transmittance.
Key Features
Laboratory Configuration for Controlled UV Irradiation
Controlled UV Irradiation
Ozone-free quartz tubular medium-pressure mercury-vapor arc lamp.
Rotating Sample Drum
Sample drum rotates from 1–5 rpm to support more uniform irradiation.
Temperature Control
Controlled chamber temperature from ambient temperature to 100°C.
Extended Exposure Testing
Programmable exposure duration from 0–300 hours.
Laminated Glass Testing
Suitable for automotive, architectural and fire-resistant laminated glass specimens.
Automatic End-of-Cycle Stop
When the preset irradiation time is reached, operating functions stop while the main power remains in standby.
