BONAD Xenon Lamp Aging Test Chamber – Accelerated UV & Environmental Testing

Material degradation caused by sunlight, temperature fluctuations, humidity, and condensation significantly affects product lifespan. The BONAD Xenon Lamp Aging Test Chamber (BND-HXD-800L) provides a precise laboratory solution by combining “natural simulation + accelerated aging” methodology. Equipped with a full-spectrum water-cooled xenon arc lamp (280–800 nm), the chamber reproduces destructive ultraviolet (UV) and visible light, while integrated temperature, humidity, and water spray control create alternating cycles of light exposure → high temperature → spray → low temperature condensation. This approach compresses months or years of outdoor aging into days or weeks, offering reliable and reproducible data for material R&D, quality inspection, and compliance testing.

Introduction to BONAD Xenon Lamp Aging Test Chamber

Industries such as coatings, plastics, textiles, electronics, and automotive rely on material durability for long-term product performance. Traditional outdoor aging tests are time-consuming and easily affected by uncontrollable factors such as regional climate variations, seasonal shifts, and atmospheric pollution. The BONAD Xenon Lamp Aging Test Chamber overcomes these limitations by simulating real-world environmental stressors in a controlled laboratory setting. Its high spectral similarity to sunlight, precise environmental regulation, and compliance with international standards including ISO 4892-2, ASTM G155, SAE J2412, and GB/T 16422.2 make it an essential tool for accelerated material testing.

Core Working Principle

Full-Spectrum Sunlight Simulation

The chamber uses a 4.5 kW water-cooled xenon arc lamp with an average lifespan of 1200 hours. Unlike conventional fluorescent lamps, it reproduces the full sunlight spectrum (280–800 nm):

  • UV-B and UV-C (280–340 nm): Simulates shortwave UV photodegradation, critical for plastics and coatings.
  • UV-A (340–400 nm): Accelerates surface oxidation and polymer chain degradation.
  • Visible Light (400–800 nm): Mimics fading, gloss loss, and color changes under sunlight exposure.

Spectral similarity exceeds 90% compared with natural sunlight, ensuring high fidelity in photodegradation studies. Adjustable irradiance at 340 nm (0.35–0.6 W/m²) and blackboard temperature 45–100 °C allow precise control over the testing environment.

Multi-Factor Cyclic Aging Environment

The chamber integrates temperature, humidity, and water spray modules to create controlled environmental cycles:

  1. Light Exposure: Xenon lamp irradiance simulates sunlight; blackboard temperature reflects surface heat.
  2. High Temperature Stage: Chamber temperature 0–80 °C (±2 °C) accelerates thermal oxidation and material breakdown.
  3. Spray Stage: Adjustable water spray (0.12–0.15 MPa) simulates rainfall and moisture impact.
  4. Low Temperature Condensation: Temperature drops to 50 °C ±2 °C, humidity 80–95% RH, simulating night dew and promoting electrochemical corrosion on metals and coatings.

This cycle fully simulates sunlight, temperature, and humidity, dramatically accelerating aging processes. For example, automotive paint degradation that takes six months outdoors can be reproduced in 2–3 weeks in the chamber.

Advanced Testing Features

BONAD chambers support customizable test protocols, enabling industry-specific testing:

  • UV Stabilization Testing: Evaluate effectiveness of UV inhibitors in plastics and coatings.
  • Thermal Cycling & Stress Cracking: Test materials under alternating high and low temperatures for thermal expansion resistance.
  • Condensation & Corrosion Testing: Simulate dew and moisture to assess electrochemical corrosion of metals and coatings.
  • Spray Erosion Testing: Adjustable nozzle pressure and cycle to simulate long-term rain or acid rain effects.
  • Data Logging & Analysis: Continuous monitoring of irradiance, temperature, humidity, and black panel temperature for traceable, reproducible results.

Standard Test Procedures
