Testing principles and methods:
Test environment temperature 10 ~ 40 ° c;The windscreen stays wet;Test water should be kept clean and free from any impurities.
Hardness is not higher than 205 g / 1000 kg, the water temperature is not higher than 38 ℃.
When the nominal voltage is 12V, the test electrical pressure is 13.5V±0.3V.When the nominal voltage is 24V, the test voltage is 27V ±0.6v.
The outside surface of the windscreen should be kept clean and free from oil and dirt
