Do you know how to test the water resistance of cars? See how they do it in Škoda

Of course, new cars go through a series of tests and trials. During production, for example, their watertightness is also checked. The Czech carmaker Škoda describes exactly how this process works.

At the same time, it has been using the watertightness test room since 1982. Recently, however, it has modernized it and, according to Jaroslav Kasl, head of the Škoda Quality Management Department, has also doubled its capacity.

The way the test room works with water is already interesting. All water used for watertightness tests is recycled. Ten cubic meters of water from the sump circulates in a closed circuit of the test room, up to 375 liters are recycled per minute, and up to one million liters per month during intensive operation.

During cleaning, the water passes through coarse and fine filters and is disinfected with UV radiation every night. The water in the circuit is also changed once a month, and the cleaned water then drains into the sewer.
