Products Description
0 to 4℃ Temperature Shock with Splash Water Test Chamber for Automotive Components
Overview:
This test equipment 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.
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).
Standards compliant:
Structure:
Chamber type structure, heating and ice water impact are completed in two chambers, with partitions in the middle
Technical parameters:
AC380V single-phase R, N + protection ground;
voltage allowable fluctuation range of 10% V;
