Why Xenon Arc Testing Is the Industry Gold Standard

Accelerated weathering tests are not all the same. Your choice of light source is absolutely crucial to how well your test results match outdoor reality.
This is how xenon arc testing trumps other methods.
Solar Spectrum Simulation Capability:
The xenon lamps provide the complete spectrum of the sun’s rays – from UV to visible to infrared radiation.

• The use of optical filters (such as those for sunlight or glass) enables the adjustment of the spectral distribution in accordance with various test applications – outdoors or inside with glass transmittance.
• Conversely, fluorescent lamps emit only ultraviolet radiation and cannot replicate the visible and infrared spectra that cause degradation in some samples.

Controlled Irradiance Level:

• The lamp output irradiance level is controlled via feedback control circuitry to ensure a constant UV dose during exposure testing.
• Irradiance can be varied from 0.5 to 2.0 W/m² at 340 nm to enable acceleration factors appropriate to certain climates.

Multi-Stress Exposure Capability:

• Different levels of temperature, humidity, and water spray can be controlled and cycled simultaneously with the UV exposure for realistic testing conditions.
• Multi-stress capability is crucial when testing materials that experience more than one stress simultaneously, such as automotive paint.

International Standard Compliance:

• Xenon arc testing is mandated by ASTM G155, ISO 4892-2, ISO 105-B02, SAE J2527, and many OEM-specific specifications that cannot be met with any other light source.

How Does Xenon Arc Testing Work? Step-by-Step Process

The importance of knowing how the xenon arc UV test works allows test operators to properly configure and evaluate results. Below is an explanation of the test cycle in a xenon arc chamber:

• Optical Filter Selection: Depending on whether your material will be exposed directly under sunlight outdoors or indoors, select the proper optical filter, either a daylight filter or a window glass filter.
• Sample Preparation & Placement: Cut samples into a 150 × 70 mm size (or place entire components), and place them inside the sample holders located in the exposure section.
• Test Program: Set up all test parameters like irradiance set point, chamber temperature, spray intervals, and overall duration of test using the HMI touchscreen.
• • Xenon Arc UV Exposure Phase: The specimens are exposed to the 1.8 kW xenon arc lamp with a controlled, continually adjusted irradiance. This is accomplished via a closed-loop irradiance control system that compensates for age-related changes in lamp power automatically.
• Moisture / Water Spray Phase: Every once in a while, the water spray system is switched on to create rain, dew, or humidity effects. The temperature is separately regulated using the PID control.
• Data Recording and Monitoring: Irradiation dose accumulated during the process, chamber temperature, spray duration, and overall duration of testing is displayed in real time on the HMI. The results of testing can be saved for documentation purposes.
• Testing: Once the xenon arc exposure phase is completed, samples are evaluated according to one of the failure criteria listed below, which are set by the relevant standard.

Frequently Asked Questions (FAQs) About Xenon Arc Testing

Q: What is the difference between xenon arc testing and UV fluorescent lamp weathering testing?

Answer: Xenon arc aging test involves using a xenon arc lamp together with optical filters to simulate the entire solar spectrum, including ultraviolet, visible light, and infrared radiation.

This test is more correlated with outdoor exposure. The aging test using a UV fluorescent lamp involves simulating just the ultraviolet part of sunlight.

It is less correlated with outdoor exposure than the xenon arc aging test since some substances are degraded by visible and near-infrared radiation in addition to ultraviolet light.

Xenon arc aging test is preferred in applications where correlation with outdoor exposure is important such as automotive OEM qualification, exterior architectural coating, and textile colorfastness.

Q: Which international standards does xenon arc UV testing comply with, and how do I know which one applies to my product?

Answer: The most frequently used xenon arc testing standards are ASTM G155 (for general non-metallic materials), ISO 4892-2 (for plastics), ISO 105-B02 (for textile color fastness), ISO 11341 (for paints and coatings), SAE J2527 (automotive exterior), and SAE J2412 (automotive interior).

Depending on what kind of material you are dealing with and the requirements of your customers or certification agencies, the applicable test standard may differ. For exports to Europe, it is more common to use ISO standards, while automotive OEMs in North America use SAE standards.

In case of doubt about the applicability of the test standard, our technical team at Effective Lab India can help select the suitable test procedure, filter type, irradiance level, and duration of the test.

Q: How often do the xenon arc lamp and filters need to be replaced, and does Effective Lab India provide spare parts and after-sales support?

Answer: The life span of the 1.8 kW Xenon Arc Lamp used in the Effective Lab India chamber ranges from 1,500 to 2,000 hours. The actual life span depends upon several factors.

The HMI device keeps track of the number of lamp hours. Replacing the lamps once they reach the specified life expectancy helps ensure irradiance accuracy. Optical filters need to be regularly checked to detect any loss in efficiency due to solarization.

Filters need to be changed in case their transmittance deviates from the stated specifications. Replacement lamps and filters, including daylight and window glass, along with other consumables, are supplied by Effective Lab India directly.
