Bench UV Light Accelerated Weathering Chamber
A Bench UV Light Accelerated Weathering Chamber is a small-sized laboratory piece of equipment used to mimic the effects of natural outdoor conditions such as sun rays, moisture, and heat.
The device accelerates the weathering process by subjecting the test material to an array of simulated environmental factors, including UV light exposure, condensation, and heat for a few days or weeks, which otherwise may take several months or even years under actual weathering conditions.
Â
Most cases of material degradation caused by weathering can be attributed to the effects of ultraviolet rays from the sun on polymer products, coatings, paint, rubber, textile fabrics, and adhesives.
All these processes, including fading, chalking, cracking, delamination, loss of tensile strength, and brittleness, are initiated by UV photo-degradation. The Bench UV Light Accelerated Weathering Chamber offers an accurate, reliable, and affordable method of anticipating such product defects before they reach the consumer.
The Bench UV Light Accelerated Weathering Chambers at Effective Lab India are designed based on international test standards, are user-friendly, and provide effective after-sales service. These devices are utilized extensively throughout India’s auto, coatings, plastic, textiles, and construction sectors.

Why UV Weathering Testing Is Essential for Your Products
Photodegradation affects any substance that is subjected to the sun’s rays. The extent to which the material degrades depends on the exposure to UV light, the temperature, and the presence of water. When it comes to business organizations, predicting how the materials will behave under certain environmental conditions becomes critical for their success.
Failure to test the products before distribution results in losses in terms of damaged reputation and possible liabilities. With a Bench UV Light Accelerated Weathering Chamber, businesses can detect potential defects at an early stage, when it is still easy and economical to fix them.

This device is a miniature version that can be easily positioned on the lab bench but has the entire functionality of a floor-mounted weathering chamber. The chamber employs UV lamps for the simulation of the short-wave portion of the sun rays and a condensing apparatus to simulate moisture exposure, which causes accelerated aging of the materials.
The specimen rack can accommodate as many as 18 samples of panels, sized 150 x 70 mm, and rotate all through the test process. This type of rack design provides the specimens with an even distribution of the irradiation energy, and no sample can be exposed to more UV energy than others due to its location.
All the test parameters are controlled from the HMI touch-screen; these include the level of UV intensity, temperature inside the chamber, time of spraying water, and test cycle programming. There is also a screen displaying such data as total time of testing, temperature inside the chamber, time of UV irradiation, and time of spraying water.

How Does the Bench UV Light Accelerated Weathering Chamber Work?
The underlying mechanism of operation for the testing chamber is relatively simple and meant to replicate the two most significant weathering forces in nature: UV radiation and moisture. In an example test sequence, the following steps occur:
- Sample Preparation: Panels are sized down to 150 x 70 mm and attached to the rotating test panel holder, set 50 mm away from the UV light sources.
- Test Parameter Input: The tester inputs the required parameters for testing through the HMI touch-screen interface.
- Phase of UV Irradiation: During this stage, the UV fluorescent lamps irradiate the samples as they rotate around on the holder to ensure consistent exposure.
- Phase of Condensation / Moisture: During this phase, the water spray system sprays the specimens to emulate dew, rainfall, and humidity conditions.
- Repetition of Test Phases: UV exposure and condensation phases alternate until the programmed number of cycles elapses.
- Test Sample Analysis: Following testing, the samples are compared to untested samples, and their physical properties, such as changes in colour, loss of gloss, cracking, and chalking, are measured.

Choosing Between UVA-340 and UVB-313 Lamps
Among the critical considerations involved when setting up the UV Weathering Test is choosing the type of lamp to use. Effective Lab India’s Bench UV Light Accelerated Weathering Chamber comes in two types – UVA-340 and UVB-313 lamps – depending on what the test entails.
UVA-340 Lamps (Best For Almost All Testing Scenarios):
- Closely matches the spectral distribution of sunlight within 360nm (the wavelengths that cause actual damage to polymers/coatings)
- Results mimic those obtained from natural weathering experiments
- ASTM G154 and ISO 4892-3 recommended for most material testing cases
- Irradiance of 0.7W/m² at 340 nm
UVB-313 Lamps (For Fast Testing And Comparison):
- Emit short-wavelength UV <300nm (more energized compared to sunlight)
- Results obtained faster; suitable for comparative testing and quality control purposes
- Should not be used where exact correlation is required
- Irradiance of 0.4W/m² at 313nm
We have a technical team that will recommend the best lamp depending on your material and application area.

Know About Our Products
The Bench UV Light Accelerated Weathering Chamber offers precise, multi-environment testing by combining salt spray with humidity, drying, and condensation cycles. It rigorously simulates harsh conditions to assess material durability, ensuring your products withstand corrosion and deliver long-lasting performance in challenging environments.
Q: How long should a test last?
A: The test duration depends upon the material being tested, its failure criterion, and the particular test methodology employed. Tests can last between 100 to 2,000 hours of UV radiation. The acceleration ratio of years simulated per hour of testing varies depending upon the material being tested and the level of UV light exposure, but it usually lies between 5:1 to 20:1 when compared to exposure outdoors in a temperate climate. For instance, 500 hours of exposure to UVA-340 light in the Bench UV Light Accelerated Weathering chamber is frequently used to simulate several years of exposure of paints and coatings outdoors.
Q: What are the most common maintenance procedures?
A: The most common maintenance procedures include replacing the UV lamp (using the built-in hour meter), cleaning the interior of the chamber and water system, and yearly calibration for ensuring accurate temperature control and measuring UV irradiance values. Efficient Lab India ensures excellent post-sale support through providing installation, training of operators, and calibration services. Lamps and other replacement items may be purchased directly from us, which will allow you to avoid downtime. Our engineers are located throughout India and can provide prompt assistance when needed.
UV stands for Ultraviolet. It is a type of electromagnetic radiation that comes from the Sun. UV rays are invincible from the human eyes but can have harmful and beneficial effects on human health.
