Accredited Accelerated UV Ageing and Solar Radiation Testing
At EMC Technologies, we provide accredited accelerated UV exposure services to help manufacturers understand how materials and products respond to long term sunlight, heat and environmental stress.
Our laboratories operate advanced UV accelerated ageing chamber systems specifically designed to replicate the full spectrum of outdoor UV conditions in a controlled, repeatable setting. Our testing facilities validate product durability, demonstrate compliance and identify risks early in the development cycle.
What is Accelerated Weathering?
An ageing test evaluates how materials respond to ultraviolet light, heat and moisture in a controlled environment. Instead of relying on long-term outdoor exposure, accelerated weathering applies intensified UV levels so degradation can be quickly detected. This testing supports faster product validation, risk reduction and compliance work.
In Australia, we have some of the world’s highest UV levels, making accelerated testing essential for products used outdoors.
Our engineers use a controlled UV ageing test chamber to reproduce these conditions with consistent irradiance and temperature to assess long-term durability accurately.
Key Degradation Effects We Test For
At EMC technologies, we evaluate a range of UV-related degradation mechanisms, including:
- Surface fading, discolouration and gloss loss
- Cracking, brittleness and changes in tensile strength
- Polymer breakdown and coating failure
- Material softening or embrittlement
- Changes in electrical or mechanical performance
Testing to Global Standards for UV Exposure
Our engineers perform accelerated ageing test programs aligned with internationally recognised defence, commercial and industry requirements. We support clients through test plan development, sample preparation, exposure schedules and data interpretation.
MIL-STD-810 Solar Radiation (Method 505)
At EMC Technologies, we conduct MIL-STD-810 Method 505 solar radiation testing to assess heating and actinic effects from sunlight. This process evaluates surface damage, thermal load and long-term material stability for defence, transport, aerospace and outdoor commercial products.
Using a controlled solar radiation test chamber, we apply set UV intensity and temperature cycles to create repeatable exposure conditions that natural sunlight cannot provide.
Commercial and Industry Standards (ASTM / ISO)
Our laboratories also support commercial UV testing to standards including ISO 4892 series and ASTM D4329. These procedures cover:
- Plastics
- Coatings
- Composites
- Rubbers
- Other materials sensitive to UV ageing
Testing provides quantifiable evidence of durability and helps manufacturers verify performance claims for applications in construction, automotive, marine and consumer goods.

The Testing Process
A typical ageing test program includes:
- Reviewing standards and exposure requirements
- Setting UV levels, temperature profiles and cycle durations
- Mounting samples inside solar radiation test equipment
- Monitoring irradiance and chamber conditions
- Inspection of materials after exposure and reporting on results
All of these controlled methods ensure reliable results using our UV accelerated ageing chamber systems.

FAQs about Accelerated UV Exposure Testing
What is the UV acceleration test?
UV acceleration testing is a controlled exposure procedure using a UV accelerated ageing chamber to simulate high-intensity outdoor UV in a repeatable way.
How does accelerated UV ageing compare to real-time outdoor exposure?
Accelerated testing intensifies UV levels to compress months of sunlight into a shorter period, providing consistent data for an ageing test.
What types of materials are most susceptible to UV degradation?
Plastics, rubbers, coatings, adhesives and polymers typically require an accelerated ageing test due to their sensitivity to UV breakdown.
What is the difference between actinic and heating effects?
Actinic effects are chemical changes from UV light, while heating effects relate to temperature rise during a solar radiation test.
How do you measure UV exposure?
UV exposure is measured using calibrated sensors that track irradiance and cumulative dose inside a solar radiation test chamber.
