Austest Laboratories operates 2 types of accelerated weathering chambers, providing full coverage of Solar and UV radiation exposure.
What is Solar Radiation Testing?
Solar radiation testing evaluates how materials and products perform when exposed to sunlight over time. It’s commonly used for plastics, coatings, paints, textiles, and other materials designed for outdoor or high-UV environments.
In a controlled solar testing laboratory, the effects of long-term outdoor exposure are replicated using accelerated test methods. A solar radiation test simulates the full spectrum of sunlight, including Ultraviolet (UV), visible and infrared energy.
The results from these tests provide a clear understanding of product performance, supporting manufacturers, importers, and suppliers in assessing durability, meeting compliance requirements, and making informed decisions before going to market.
Our Weathering Simulation Technology
At Austest, we provide accredited solar radiation testing using a high-capacity Xenon Arc chamber.
Xenon Arc Solar Radiation Chamber
For a full-spectrum solar radiation test, our Xenon Arc Solar Radiation Chamber reproduces natural sunlight, including ultraviolet (UV), visible light, and infrared. Combined with water spray and humidity, it allows us to assess fading, colour change, and overall material performance.
Available test standards:
- IEC60068-2-5:2018, Sa1, Sa2, Sa3, Sb1, and Sb2
- ISO 4892-2:2013, Method A, Cycle 4
- ASTM G155-25, Cycle 1
Industry Applications for Solar Weathering
Various industries rely on accelerated aging to ensure long-term product safety and aesthetic appeal. Our solar radiation test capabilities are essential for evaluating the UV weathering resistance of:
- Automotive Components: Testing exterior trims, dashboards, and accessories to prevent cracking or fading.
- Aerospace & Defence: Ensuring mission-critical equipment remains functional under high-altitude solar intensity.
- Consumer Goods & Textiles: Assessing the performance of outdoor furniture, performance apparel, and sports equipment.
By simulating the destructive effects of sunlight and moisture, solar radiation testing helps identify potential material failures before they reach the market.

FAQs About Solar Radiation Testing
How does a solar testing laboratory accelerate the weathering process?
In our laboratory, we use high-intensity Xenon Arc lamps and controlled environmental cycles. By providing continuous exposure and alternating between light, heat, and moisture, we can simulate years of outdoor exposure in months.
How long does accelerated weathering take?
A solar radiation test typically runs from a few weeks to several months, depending on the material and test requirements.
Can I test an entire finished product, or just material samples?
You can test both. Our solar radiation laboratory supports testing at the material level or on fully assembled products, depending on what you need to assess. We’ll guide you on the best approach to get meaningful, reliable results.
Does accelerated weathering testing include moisture and rain?
Yes. Many solar radiation tests include moisture, such as condensation or water spray, to reflect real outdoor conditions. This combined approach gives you a more accurate picture of how your product will perform over time.
