Carbon arc aging chamber is mainly used to simulate the destructive effects of ultraviolet rays, temperature, humidity and other factors in natural climate on materials, and accelerate the aging process of materials through the radiation generated by carbon arc lamps. It is often used in industries such as plastics, rubber, and coatings to help evaluate the aging resistance of materials in order to improve product quality and extend service life.

Applications

The Carbon Arc Aging Chamber employs alternating current to ignite carbon rods, generating an arc light source. After passing through a filter, this light possesses higher irradiance than sunlight, thereby accelerating sample aging when directed onto surfaces. Equipped with a spray system, it simulates not only sunlight exposure but also rainfall conditions, enabling effective accelerated testing of samples' weather resistance.

Standards

JIS B7753 Sunlight Carbon Arc Lamp Test for Lightfastness and Weather Resistance

ISO 4892-4 Plastics - Laboratory light exposure methods - Part 4: Open carbon arc lamp

Features

Accelerated Weathering: Rapidly simulates sunlight, artificial light, and rainfall, providing faster results than natural aging.

High-Intensity Carbon Arc: Uses 4 pairs of carbon electrodes (2 upper, 2 lower) to generate stable, high-intensity light similar to solar spectrum.

Filtered Spectrum: Light passes through high-quality filters to reproduce sunlight-like wavelengths, ensuring consistent irradiation on test surfaces.

Precision Electrode Control: Automatic vertical movement of carbon electrodes maintains stable voltage and current within strict tolerances.

Moisture Simulation: Programmable spray system replicates rainfall exposure during testing.

Large Sample Capacity: Accommodates up to 76 test specimens simultaneously.
