VW80000 Ice Water Splash Test Equipment For Automotive Parts

System Information

This test equipment is designed and manufactured according to ISO 16750-4:2010 clause 5.4 and VW80000: 2009-10, etc.

It simulates the thermal shock test caused by ice water for products used in shallow water areas of vehicles components. The purpose is to simulate icy water splashing onto heating systems or components when driving on wet roads in winter. The failure mode is either mechanical cracking of the material or seal failure due to a different temperature expansion coefficient.

Working principle:

Heat the DUT (device under test) to a certain temperature and a specified time in the test chamber. Then spray the DUT with ice water for 3s. If the DUT is only splashed in one direction on the vehicle, spray water only in this direction of the installation location. If the equipment is exposed to water splashing in multiple directions on the vehicle, these directions shall be stated and a new DUT shall be tested in each direction. The width of the splash is controlled to always be greater than the width of the DUT.
