If no part of the windscreen washer system is situated in the engine compartment, the system shall be filled with water, fully primed, and placed in an ambient temperature of 80 ± 3 °C for a minimum of eight hours. The water does not have to be stabilized at this temperature. Subsequently, the system is placed in an ambient temperature of 20 ± 2 °C. When the temperature of the water has stabilized, the performance of the windscreen washer system shall be verified by actuating the system in accordance with paragraph 2.2.1.1. to 2.2.1.2. After this, the system shall be filled with water, fully primed, and placed in an ambient temperature of 60 ± 3 °C for a minimum of eight hours. The water does not have to be stabilized at this temperature. The performance of the windscreen washer system shall then be verified by actuating the system in accordance with paragraph 2.2.1.1. to 2.2.1.2. Alternatively, the manufacturer may request that the windscreen washer system is tested under the conditions as set out in paragraph 2.2.4.1.
