Ice Water Shock Test Chamber

1. Introduction

The ice water shock test chamber can meet the test requirements of ISO16750-4 clause 5.4.2 and clause 5.4.3. The equipment can perform splash water test and submersion test separately. For splash water test, The DUT is placed on the heating chamber, and heat it at Tmax for 1 hour (or until DUT temperature stabilization is reached), then use a jet to splash the DUT with cold water (0℃~+4℃) for 3s. The immersion tank (cold water tank) is under the heating chamber, when perform the submersion test, operate the DUT in the heating chamber at Tmax for 1 hour (or until DUT temperature stabilization is reached), with the device still operating, submerge it for 5min in cold water tank at a depth of ≥10mm.

The ice water shock test is to simulate a thermal shock induced by cold water and is applicable to products in the splash areas of the vehicle. The purpose is to simulate cold water splashing over a hot system or component, as can happen when a vehicle is driven on wet roads in winter. Failure modes are mechanical cracking of materials or seal failures caused by different temperture expansion coefficients. Splash water test and submersion test are two alternative methods for performing the ice water shock test.
