Solar Simulation Chamber → Metal Halide Lamp Test Chamber → DIN 75 220

Wewon Tech has developed solar simulation chambers for automobile components customers according to DIN 75 220 test standard. The design of solar simulation chambers from Wewon Tech meets the specific requirements of DIN 75 220 Table 1 for the irradiance spectrum. According to the requirements of the test standard, a sunlight simulation system must be installed to simulate the light aging characteristics of the whole vehicle or component. The metal halide lamps shall be assembled on the rail brackets in the solar simulation unit.

Test engineer can use the DIN 75 220 test to evaluate changes in the performance of parts or vehicles after irradiation, including changes in shape, color, gloss, feel, strength, sealing, and changes in artificial full irradiation, heat/cold and various thermal expansion results under the action of humidity were evaluated. The DIN 75220 test standard is mainly designed for automobile sunlight simulation aging test.

Determination of the ageing characteristics of polymeric automotive structural components in their original structural position and manner of assembly by completing DIN 75 220 test trials. This method is applied to vehicle assembly components or entire vehicles and is therefore particularly suitable for revealing the interaction of various materials within a structural member or between structural members. The light stand is fixed on the top, but the light field can obtain light intensity with uniformity within ±10% at different heights.

We use German original metal halide lamps and dimmers, which are specially designed for daylight simulation experiments to simulate the real solar spectrum. Metal halide lamp test chambers evaluate the ability of equipment used and stored outdoors to withstand direct solar radiation to produce thermal and optical effects. After the test, the appearance and working performance of the product are verified to evaluate whether the materials and devices of the product can resist the requirements of outdoor solar radiation.
Multi-variable control, users can choose light intensity feedback or black body temperature feedback control mode. Equipment Features
Imported metal halide lamps ensure no drift in chromatography during the service life. Imported power supply ensures accurate power output and can effectively prolong lamp life.
The light stand can be raised and lowered, the automatic positioning motor system, and the angle of the light stand can be adjusted. It can be designed as a movable light stand according to customer needs.
Metal lampshade, equipped with filter glass, easy to disassemble structure, easy to replace the lamp. Solar simulation chambers from Wewon Tech are also suitable for solar radiation testing of aircraft, unmanned surveillance equipment.
A metal halide lamp is a gas discharge lamp that energizes with a metal halide to provide a distribution of spectral energy very similar to direct and diffuse. The method has high efficiency, and a single irradiation light source effect can be produced by placing a plurality of radiation light sources in a certain manner. The spectral distribution of metal halide lamps is very similar to the sunlight received by the earth’s surface, but due to the relatively large scale of metal halide lamps, it is mainly suitable for artificial light aging accelerated tests of large equipment such as automobiles and their parts and electrical and electronic products.

During the test, different test methods and different test periods can be selected according to different use conditions. According to the test standard of MIL-STD-810 Method 505.4, the first procedure is the cyclic test and the second procedure is the steady state test. Program 1 focuses on the effects and influences produced by solar radiation; Program 2 focuses on photochemical effects produced by solar radiation. Wewon’s solar simulation system comply with the test standard, such as DIN 75 220, MIL-STD-810 Method 505.4, GJB 150.7A-2009

The solar simulation test is essential for all applications in which it is necessary to determine how products and materials react to solar radiation over their useful life. There are many reference standards for testing resistance to solar radiation over time. Two examples: DIN 75220 and MIL-STD-810 tests|Page Source: How Can We Ensure That A Product Meets Certain Requirements Before It Is Put On The Market?
Determination of materials and components resistance for solar radiation is very important aspect of products’ quality evaluation. Simulation of external conditions effect on materials may be performed with various methods. In case of solar radiation simulation the kind of light source is of great importance due to differences in spectral characteristics. Radiation emitted by metal halide lamp very closely simulate spectral energy distribution and intensity of solar radiation – in reference with CIE publication No. 85 (spectral range: UV-VIS-IR i.e. 280 ÷ 3000 nm) with fully regulated intensity. Testing in Solar Simulation Chamber – Metal Halide Lamps
Testing of components and assemblies in solar simulation chambers allows determination of changes in such properties as shape, color, gloss or strength. Other characteristics that are common evaluated are presence of stains, cracks or delamination and other aesthetic and functional aspects|Page Source:
Although DIN 75220 does not specify the light source, the de-facto standard for this method always has been metal halide lamps. They are ideal for large scale solar simulation testing because of their (1) Good simulation of the complete solar spectrum in the UV, visible and IR wavelength regions (2) High light efficacy. Xenon or Metal Halide? Can Xenon Support Automotive Interior Component Testing According to DIN 75220?
Can xenon support automotive interior component testing according to DIN 75220?” My answer is: “Not really”. Xenon’s strengths remain in the benefits required for UV durability testing. However, professional aging testing of vehicle interior components is more dependent on the correct temperature profile (specimen size, shape, position) and microclimate condition|Page Source:
DIN 75220 describes the irradiation of automotive interior and exterior components in a sun simulation chamber. A distinction is made between cycle and endurance tests; climatic stress (humidity and temperature) can also be simulated. Common automotive standards that refer to DIN 75220 are, for example, VW/Audi TL 226 or TL 52013. Other OEMs are Daimler in the delivery conditions DBL 5404 / DBL 9202 or BMW in the test specification GS 95024-3-7|Page Source: DIN 75220 Ageing Of Automotive Components In Solar Simulation Facilities
