Auto Parts Test Equipment ISO 16750 Ice Water Shock Test For Electronic Components
Standard:
VW-80000 Electric And Electronic Components In Motor Vehicles up to 3.5t General Requirements, Test Conditions and Tests clause 9.12 K-12 Temperature Shock With Splash Water;
ISO16750-4 Road vehicles-Environmental conditions and testing for electrical and electronic equipment-Part 4: Climatic loads clause 5.4.2 Ice water shock test.
Purpose:
This test simulates a thermal shock induced by ice water and applies to products in the splash areas of the vehicle. The purpose of this test is to simulate ice water splashing over a hot system/component. This happens when driving on wet roads during the winter. Failure modes are mechanical cracking of materials or seal failures caused by different temperature expansion coefficients. Auto Parts Test Equipment
Test method:
Splash water test:
Heat the DUT in a hot air oven at T max for the specified holding time, t h . Then splash the DUT with ice water for 3 s.
If the DUT is splashed in the vehicle from only one direction, splash it from this direction only while it is in an as-installed position. If the equipment is splashed from various directions in the vehicle, then these directions shall be taken into account. In this case, use a new DUT for each splash direction. The width of the splash directed at the DUT shall always be greater than the width of the DUT. If the DUTs to be splashed prove too big for one jet, arrange several jets in a row to produce a line of splash impact on the DUT. See Figures 4 to 6.
Test parameters include:
⎯ number of cycles: 100;
⎯ holding time, t h , at T max : 1 h or until DUT temperature stabilization is reached;
⎯ transition duration: < 20 s (for manual transition of DUT between temperature storage and splashing);
⎯test fluid: de-ionized water;
⎯ water temperature: 0 °C to +4 °C;
⎯ water flow: between 3 l and 4 l per 3 s (splash duration);
⎯ distance between jet and DUT surface: (325 ± 25) mm (water shall be applied over the complete width of the DUT);
⎯ operating modes: see Figure 5;
⎯ orientation of the DUT: as in the vehicle.
