Principle: This test method can improve the performance evaluation of automotive interior parts and interior parts by simulating the harsh environmental conditions existing in the actual use of the interior of the car, and strengthening environmental factors such as light, heat and moisture. The purpose of the estimate.
Test equipment requirements
1. The equipment manufacturer is responsible for the test equipment and must provide key parameters of the test equipment, including spectral energy distribution. Test equipment should be tested for comparison with standard reference materials such as AATCCL-4 and L-2 blue wool standard fabrics. Equipment manufacturers should provide the necessary data to demonstrate the comparability of test results between different types of equipment. The most basic data should include the relative spectral energy distribution between 250mm and 800mm and the repeatability and reproducibility of standard reference materials. data. Both sides of the test should confirm the type of equipment before the test.
Note: In daily tests, different equipment may result in different test results. The test results depend on the characteristics of the test sample and the design of the test equipment.
2. The test equipment uses a xenon arc lamp as the irradiation source. The test sample is installed in the test chamber and the test conditions of the test sample are to be consistent. The test equipment must be able to automatically control the irradiance, the temperature of the blackboard, the temperature inside the box and the relative humidity inside the box in a certain way. Before the test begins, both parties should agree on the type of test equipment manufacturer and test equipment. (Note: For a more detailed description of the test equipment, refer to ASTMG151 and ASTMG155.)
3. The test equipment shall be fitted with a blackboard thermometer unless otherwise agreed by the test parties.
4. The test equipment shall be designed to ensure that the irradiance at the protected position in the exposed area of ​​the test sample is at least 70% of the maximum irradiance of the area. If the irradiance at the farthest end from the exposure center position is 70% of the central irradiance %-90%, the test sample must be placed within the area of ​​90% of the maximum irradiance that can be achieved.
