Equipment Overview
Samples and Restrictions: Automotive electrical and electronic components, dimensions to be determined. This test equipment prohibits the tests of flammable, explosive, volatile substances; the test of stored corrosive substances; the tests of storage of biological; the tests of storage of strong electromagnetic emission samples.
Application: This test simulates the load of the component when exposed to splash water as it occurs when driving through puddles. The test serves to verify functioning of the component when subjected to shock-type cooling by means of water. This happens when driving on water roads during the winter. Failure modes are mechanical cracking of the materials or seal failures caused by different temperature expansion coefficients.
Principle: Spray the sample heated to the test temperature with a de-ionized water (0-4°C, tap water containing 3% Arizona dust by weight, fine, in accordance with ISO 12103-1. Permanent mixing shall be ensured), at a distance of 300-350 mm from the sample. Each splash duration 3 s, and the water flow is 3-4liters per splash/nozzle. The transition duration ＜20 s (for manual transition of DUT between temperature storage and splashing) (only required by ISO 16750-4 and GB/T28046.4).
Use Environment: The ambient temperature is +25 ° C, the relative humidity is ≤ 85% R. H, and the value measured under the condition of no sample in the test chamber.
Structure: Chamber type structure, heating and ice water impact are completed in two chambers, with partitions in the middle.
