Coil Steel Sunshine Carbon Arc Weathering Tester

Name: Coil Steel Sunshine Carbon Arc Weathering Tester
Brand: Xi'an LIB Environmental Simulation Industry

The Coil Steel Sunshine Carbon Arc Weathering Tester is engineered specifically for the rigorous accelerated weathering evaluation of coil-coated metals, color-coated steel sheets, anti-corrosion paints, and industrial automotive components. By faithfully reproducing the entire spectrum of natural sunlight—including ultraviolet, visible, and infrared wavelengths—along with real-world environmental stressors such as temperature changes, humidity, and water spray exposure, this equipment accurately simulates outdoor conditions and predicts long-term outdoor durability in a fraction of real time.

Using a sunshine carbon arc light source, the tester accelerates the coating aging process, helping manufacturers evaluate critical durability properties such as color change, gloss retention, chalking, cracking, and coating degradation—ensuring the reliability of steel coil products used in outdoor environments.

Model: XL-500 and more custom models

Coil Steel Sunshine Carbon Arc Weathering Tester Applicable Testing Standards

Support International Weathering Test Requirements

LIB Sunshine Carbon Arc Weathering Tester can be configured to meet relevant accelerated weathering evaluation requirements, including:

ASTM G23 – Standard Practice for Operating Light-Exposure Apparatus (Carbon Arc Type)
ASTM G152 – Operating Open Flame Carbon Arc Light Apparatus for Nonmetallic Materials
ISO 4892-4 – Plastics — Methods of Exposure to Laboratory Light Sources — Open-Flame Carbon-Arc Lamps
ISO 16474-4 – Paints and Varnishes — Exposure to Artificial Light Sources — Open-Flame Carbon Arc Lamps
JIS B7753 – Light Exposure Testing Apparatus Using Carbon Arc Lamp

Features of Coil Steel Sunshine Carbon Arc Weathering Tester

Sunshine Carbon Arc Spectrum

Utilizes advanced sunshine carbon arc lamps that match natural solar spectral energy distribution closer than standard xenon or fluorescent lamps, yielding highly reliable aging behavior for organic coatings.

Optimized Specimen Fixtures

Equipped with specialized heavy-duty holders custom-designed for steel coils, metal strips, and coated plate samples, ensuring secure mounting and uniform exposure.

Precision Environmental Control

Features intelligent programmable cycles for light exposure, dark condensation, and water spray. Black Panel Temperature (BPT) is precisely maintained to simulate harsh outdoor thermal stresses.

Robust Industrial Build

Constructed with heavy-gauge corrosion-resistant stainless steel test chambers designed to endure alternating high-humidity, high-temperature, and corrosive moisture loops.

Frequently Asked Questions

1. What materials can be tested in a Sunshine Carbon Arc Weathering Tester?

The tester can be used for a wide range of materials, including pre-painted steel coils, coated metal sheets, automotive coatings, architectural coatings, plastics, paints and other exterior materials. The appropriate test configuration depends on the material and applicable testing standard.

2. Can it be used for pre-painted steel coil testing?

Yes. The Sunshine Carbon Arc Weathering Tester is suitable for evaluating pre-painted steel coils and coated steel sheets. It can help assess color change, gloss retention, chalking, cracking and other coating degradation after accelerated weathering exposure.

3. What is the difference between a carbon arc and a xenon arc weathering tester?

Both systems are used for accelerated weathering testing, but they use different light sources and have different spectral characteristics. Xenon arc testers are widely used when close simulation of the solar spectrum is required, while carbon arc testers are specified by certain traditional weathering methods and industry standards.

The appropriate system should therefore be selected according to the material, test method and required standard, rather than simply choosing the newest light source.

4. Can the tester simulate rain and moisture?

Yes. The equipment can be configured with water spray and environmental control systems to reproduce wet/dry exposure conditions. Temperature, humidity, light exposure and spray cycles can be programmed according to the testing requirements.

5. Can LIB customize the Sunshine Carbon Arc Weathering Tester?

Yes. LIB Industry can customize the equipment according to sample dimensions, sample quantity, exposure conditions, water spray requirements, temperature and humidity requirements, and applicable testing standards.
