ASTM G154 UV Accelerated Aging Chamber

Name: ASTM G154 UV Accelerated Aging Chamber
Brand: Xi'an LIB Environmental Simulation Industry

The ASTM G154 UV accelerated aging chamber complies with ASTM G154 standards and uses fluorescent UV lamps to perform exposure tests on non-metallic materials to assess the material's weather resistance and durability in outdoor environments, such as changes in color (fading or yellowing), surface cracking or pulverizing, and changes in mechanical properties (such as tensile strength, elasticity).

ASTM G154 UV accelerated aging chamber has many customized options:size,configuration, performance, sample holder.You can create a personalized test chamber to meet your needs.

Model: UV-SI-260

Standard: ASTM G154, ASTM D 4329 – 05, ASTM C1257, ASTM C1442, ASTM C1519, ASTM C793, ASTM D1148, ASTM D3424, ASTM D3451, ASTM D4101,

ASTM G154 UV Accelerated Aging Chamber Features and Benefits

1. The UV accelerated aging chamber uses fluorescent ultraviolet lamps to simulate the ultraviolet part of sunlight: the UVA340 lamp simulates the shortwave ultraviolet (295-365 nm). The UVB313 lamp provides stronger ultraviolet radiation for accelerated material aging testing.

2. The ASTM G154 UV accelerated aging chamber can simulate high or low temperature environments to evaluate the aging behavior of materials under different temperature conditions, temperature control range: ambient to 90℃±2℃.

3. The workroom is made of SUS304 stainless steel, which is corrosion-resistant and easy to clean, and can work under long-term high humidity and high intensity ultraviolet light.

4. In the UV aging environment simulated, the temperature, spray and irradiation intensity can be controlled. The irradiation meter tracks the irradiation amount in real time and sends it back to the controller.
