2.2.2.1. The windscreen washer control shall be actuated six times in one minute, each time for at least three seconds, in accordance with paragraph 2.2.1.1.1. and 2.2.1.1.2. The system shall then be placed in an ambient temperature of 20 ± 2 °C until the ice has completely thawed. 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. U.K.

2.2.3. Test No 3. Low temperature cycle exposure test. U.K.

2.2.3.1. The windscreen washer system shall be filled with water, fully primed, and placed in an ambient temperature of – 18 ± 3 °C for a minimum of four hours so that the total mass of the water in the washer system is frozen. The system shall then be placed in an ambient temperature of 20 ± 2 °C until the ice has completely thawed, but in any case no longer than four hours. This freeze/thaw cycle shall be repeated six times. Finally, when the windscreen washer system is placed in the ambient temperature of 20 ± 2 °C and the ice has completely thawed, although the water does not have to be stabilized at this temperature, 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. U.K.

2.2.3.2. The windscreen washer system shall be filled and fully primed with a low-temperature windscreen washer fluid consisting of a 50 % solution of methanol, or alternatively isopropyl alcohol, in water with a hardness not exceeding 205 mg/l (Ca). The system shall be placed in an ambient temperature of – 18 ± 3 °C for a minimum of four hours. The fluid 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. U.K.

2.2.4. Test No 4. High temperature cycle exposure test. U.K.

2.2.4.1. If any 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. 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. U.K.

2.2.4.2. 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. U.K.

2.2.5. The windscreen washer tests as set out in paragraph 2.2.1. to 2.2.4.2. shall be carried out in sequence on the same windscreen washer system. The system may be either tested as installed on the vehicle type for which EC type-approval is sought, or separately. In case EC type-approval is sought for a separate technical unit, the system shall be tested separately. U.K.

2.2.6.2. The outer face of the windscreen shall be treated as prescribed in paragraph 2.1.8 and 2.1.9. of this Annex. U.K.

2.2.6.3. The windscreen washer system shall be actuated according to the manufacturer's instructions, taking into account paragraph 2.2.1.1.1 and 2.2.1.1.2. of this Annex. The total duration of the test shall not exceed 10 complete cycles of automatic operation of the windscreen wiper system operating at the maximum sweep frequency. U.K.

2.2.6.4. In order to verify that the requirements of paragraph 1.2.4. of this Annex are met, a trace of the relevant cleaned area shall be made and compared to a trace of the vision area A, as determined in accordance with Appendix 3 to Annex III. If it is clearly obvious to the observer that the requirements are met, it is not required that the traces are prepared. U.K.

2.2.7. The test as set out in paragraph 2.2.6. to 2.2.6.4. shall always be performed on the vehicle type for which EC type-approval is sought, even in the case when an approved separate technical unit is installed on the vehicle. U.K.
