    ISO 16750-4 Auto Parts Test Equipment Splash Water And Submersion Test Chamber


    Standard:

    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.

    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;

    GB/T 28046.4-2011 Auto Parts Test Equipment


    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.

    It is a reliability test equipment for various kinds of electronic, electrical, plastic and other raw materials and devices for cold resistance, heat resistance, ice water splash resistance test, ice water immersion resistance test and quality control engineering reliability 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. Auto Parts Test Equipment


    Submersion test:

    Connect the DUT to the test equipment. Operate the DUT in a hot air oven at T max for the specified holding time, t h. With the device still operating, submerge it for 5 min in an ice water tank at least 10 mm deep.

    Test parameters include:

    ⎯ number of cycles: 10;

    ⎯ holding time, t h , at T max : 1 h or until DUT temperature stabilization is reached;

    ⎯ transition duration: < 20 s;

    ⎯ test fluid: de-ionized water;

    ⎯ water temperature: 0 °C to +4 °C;

    ⎯ immersion time: 5 min;

    ⎯ operating mode: 3.2 in accordance with ISO 16750-1;

    ⎯ orientation of the DUT: as in the vehicle.
