Introduction to UV Testing

UV testing is a crucial process that evaluates how ultraviolet radiation affects various materials, providing valuable insights into durability. Our UV testing laboratory utilizes operating fluorescent ultraviolet lamp apparatus to simulate sunlight exposure. We offer comprehensive UV testing services, including cyclic corrosion testing, to assess environmental stressors. Our experts guide clients through the testing process, ensuring compliance with ASTM G154 and other industry standards.

UV Test Equipment

Our UV testing lab follows established standards to ensure accurate test results. ASTM G154 serves as our primary standard practice for operating fluorescent ultraviolet lamp apparatus exposure testing. We use fluorescent UV lamps to simulate natural sunlight conditions, assessing how materials respond to environmental factors including temperature. Our test parameters replicate real-world conditions with precise light intensity measurements. We also offer other test methods, such as xenon arc exposure testing, for specific testing needs.

Choosing UV Test Methods

Choosing the right UV test method ensures accurate testing results reflecting real-world conditions. Our experts guide clients in selecting suitable test methods, whether ASTM G154 standard practice or ASTM G155 xenon arc exposure testing. We consider factors such as material type, exposure conditions, and test objectives for your testing needs. Xenon arc systems offer laboratory light sources simulating the full spectrum of natural sunlight, ideal for testing materials facing direct sunlight exposure.

UV Testing Equipment

Our UV testing equipment includes advanced lamp apparatus exposure systems simulating ultraviolet radiation effects on nonmetallic materials and coatings. We utilize fluorescent ultraviolet UV lamp apparatus technology providing full spectrum UV radiation. Our test chamber replicates outdoor exposure environments, including condensation cycles and non-metallic materials testing. The equipment features constant exposure capabilities for precise control over test conditions including UV spectrum intensity and environmental parameters.

Accelerated weathering
testing

Accelerated weathering testing simulates extended UV exposure on materials in compressed timeframes. Our UV testing lab uses accelerated weathering techniques to evaluate material performance under intense ultraviolet exposure conditions.

We simulate natural sunlight conditions, including the UV spectrum and light intensity, to assess material durability and resistance. Our testing services cater to industries requiring evaluation of plastics, coatings, and materials for outdoor applications and indoor applications.

Through UV exposure testing, we help predict product performance under environmental stressors.

Exemple

EN ISO 16474‑3:2021

Title:
Paints and varnishes – Methods of exposure to laboratory light sources – Part 3: Fluorescent UV lamps

Purpose:
To reproduce the degradation effects that occur when materials are exposed to daylight or daylight filtered through window glass.

What is tested?
• UV radiation (UVA‑340, UVA‑351, UVB‑313)
• Temperature (e.g., 50–60 °C)
• Humidity and water (condensation or spray)
• The material’s resistance to these factors

Test methods (examples)
Method A – UVA‑340 lamps: Simulates short‑wavelength natural sunlight.
Method B – UVA‑351 lamps: Simulates sunlight filtered through window glass (indoor environments).
Method C – UVB‑313 lamps: Provides accelerated degradation, mainly used for quality control.

 

Each method includes different test cycles with specific settings for light exposure periods, condensation, spray, temperature, and intensity.

 

ASTM G155 – Overview (Xenon Arc Weathering)

ASTM G155 is a standard that defines methods for exposing nonmetallic materials to xenon arc light in a laboratory environment. The purpose is to simulate full‑spectrum sunlight, including UV, visible light, and infrared, often combined with moisture (spray or humidity) and elevated temperatures.

SUMMARY

What the standard is used for

ASTM G155 is commonly applied in:

  • Automotive materials
  • Plastics and polymers
  • Paints, varnishes, and coatings
  • Outdoor‑exposed components

Principle of the test

The xenon arc lamp reproduces natural sunlight as closely as possible, including:

  • UV radiation
  • Visible light
  • Infrared radiation (heat)
  • Moisture exposure (spray or humidity cycles)
  • Controlled temperature

Typical exposure conditions

Based on internal emails, common exposure durations include:

  • 200–300 hours for short screening tests
  • 2000–3000 hours for long‑term or “desert‑like” simulations

 

Comparison to other standards

  • ASTM G154 → Fluorescent UV (UVA/UVB), not full spectrum
  • ASTM G155 → Xenon arc, full‑spectrum sunlight simulation
    Internal correspondence confirms that ASTM G155 aligns with xenon‑based ISO standards such as ISO 4892‑2 / ISO 16474‑2.
