ISO 16750-4 Figure 4 Stainless Steel Test Set – Up For Splash Water Test Jet

5.4.2 Splash water test

5.4.2.1 Test method
Heat the DUT in a hot air oven at Tmax for the specified holding time,th. 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,th, at Tmax: 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.
