UV Test Chamber

  • RIUKAI TECHNOLOGY has 25+ years of experience in the field of environmental testing equipment testing to meet the needs of our customers.
UV light in sunlight and diffuse sky radiation can cause alterations in the surface of materials which, accelerated by other climate factors such as temperature and humidity, lead to the typical symptoms of ageing. Staggered simulations of natural weathering in devices always requires a restriction of the number of climate values or their cyclic alterations.
This testing instrument is widely used to create simulated climatic conditions and to study the weather-resistant properties of the material inside the laboratory. The UV test chamber is considered to be one of the most effective lab testing instruments to test the effect of environmental conditions on the products.

The function of the UV aging test chamber in the laboratory is to simulate the effects of ultraviolet (UV) radiation on materials and products. This is an essential tool for researchers and manufacturers who need to assess the durability and longevity of their products when exposed to UV light.
UV test chamber (also called UV aging test chamber, UV light test chamber, or UV accelerated weathering tester) can simulate environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, and darkness in natural climate. By recreating these conditions, they are combined into one cycle, and it is automatically executed to complete multiple cycles.

    What is the RIUKAI UV test chamber?

    A UV weathering tester, also known as a UV aging tester, is a type of laboratory equipment that simulates the effects of sunlight on the aging of materials in a natural environment. It performs accelerated weathering tests on materials by using fluorescent UV lamps to simulate UV radiation from sunlight and moisture from condensation or spraying to assess the weathering and aging resistance of materials.

    The operating principle is to simulate the UV portion of natural sunlight by using UV lamps with specific wavelengths (e.g. UVA-340 or UVB-313) to accelerate the aging process of the material by exposing the test sample to controlled conditions of light, temperature and humidity.

    Applications of the UV test chamber：

    The UV test chamber is widely used in the aging testing of coatings, plastics, rubber, textiles, automotive materials, electronic components, photovoltaic cells, etc. It helps researchers and manufacturers to quickly assess the changes in material properties, such as color change, gloss loss and deterioration of mechanical properties, during long-term use or under certain environmental conditions.

    The procedure involves setting the test parameters (e.g. light intensity, temperature, humidity, exposure time, etc.), placing the sample in the sample holder, switching on the device for the test and regularly observing and recording the changes in the sample. At the end of the test, the samples are removed and analyzed to determine the weathering and aging properties of the material.

    Test standard of the UV test chamber：

    When carrying out UV tests, the relevant international and national standards must be observed, e.g. ISO 4892-3, ASTM G154, IEC 61215, etc. These standards contain detailed instructions on test methods, equipment requirements, sample preparation and test conditions.

    In conclusion, the UV aging test chamber is an important piece of laboratory equipment. RIUKAI is not only a manufacturer of environmental test chambers, but also a professional manufacturer of UV aging test chambers, click this link for more information!
