Appendix 1 Tests on spray-suppression devices of the energy-absorber type
1. Principle
The aim of this test is to quantify the ability of a device to retain the water directed against it by a series of jets. The test assembly is intended to reproduce the conditions under which the device is to function when fitted to a vehicle as regards the volume and speed of the water thrown up from the ground by the tyre tread.
2. Equipment
See Figure 8 in Annex V for a description of the test assembly.
3. Test conditions
3.1.The tests must be carried out in a closed room with a still-air environment.
3.2.The ambient temperature and the temperature of the test pieces must be 21 (± 3) °C.
3.3.De-ionized water is to be used.
3.4.The test pieces must be prepared for each test by wetting.
4. Procedure
4.1.Secure a 500 (+ 0/– 5) mm wide 750 mm high sample of the equipment to be tested to the vertical plate of the testing equipment, making sure that the sample lies well within the limits of the collector, and that no obstacle is able to deflect the water, either before or after its impact.
4.2.Set the water flow rate at 0,675 (+/– 0,01) l/s and direct at least 90 l, at most 120 l on to the sample from a horizontal distance of 500 (+/– 2) mm (Figure 8 of Annex V).
4.3.Allow the water to trickle from the sample into the collector. Calculate the percentage of water collected versus the quantity of water sprayed.
4.4.Carry out the test five times on the sample according to points 4.2 and 4.3. Calculate the average percentage of the series of five tests.
5. Results
5.1.The average percentage calculated in point 4.4 must be 70 % or higher.
5.2.If within a series of five tests the highest and lowest percentages of water collected depart from the average percentage by more than 5 %, the series of five tests must be repeated.
If within a second series of five tests the highest and lowest percentages of water recovered again depart from the average percentage by more than 5 % and if the lower value does not satisfy the requirements of point 5.1, type-approval shall be refused.
5.3.Test whether the vertical position of the device influences the results obtained. If it is the case, the procedure described in points 4.1 to 4.4 must be repeated in the positions giving the highest and lowest percentage of water collected; the requirements of point 5.2 remain in force.
The mean of the individual results shall then be taken to give the average percentage. this average percentage must be 70 or higher.
Appendix 2 Test on spray-suppression devices of the air/water separator type
1. Principle
This test is intended to determine the effectiveness of a porous material intended to retain the water with which it has been sprayed by means of a pressurised air/water pulveriser.
The equipment used for the test must simulate the conditions to which the material would be submitted, with regard to the volume and speed of the water sprays produced by the tyres, if it were fitted to a vehicle.
2. Equipment
See figure 9 in Annex v for a description of the test assembly.
3. Test conditions
3.1.The tests must be carried out in a closed room with a still-air environment.
3.2.The ambient temperature and the temperature of the test pieces must be 21 (± 3) °C.
3.3.De-ionized water must be used.
3.4.The test pieces must be prepared for each test by wetting
4. Procedure
4.1.Secure a 305 × 100 mm sample vertically in the test assembly, check that there is no space between the sample and the upper curved plate and that the tray is properly in position. Fill the pulveriser tank with 1 ± 0,005 litres of water and place this as described in the diagram.
4.2.The pulveriser must be regulated as follows:
pressure (at pulveriser): 5 bar + 10 %/– 0 %
flowrate: 1 litre/minute ± 5 seconds
pulverisation: circular, 50 ± 5 mm in diameter at 200 ± 5 mm from the sample, nozzle 5 ± 0,1 mm in diameter.
4.3.Pulverise until there is no more water mist and note the time taken. Let the water flow out of the sample on to the tray for 60 seconds and measure the volume of water collected. Measure the quantity of water left in the pulveriser tank. Calculate the percentage by volume of water collected versus the volume of water pulverised.
4.4.Carry out the test five times and calculate the average percentage of the quantity collected. Check before each test that the tray, pulveriser tank and measuring vessel are dry.
5. Results
5.1.The average percentage calculated in point 4.4 must be 85 % or higher.
5.2.If within a series of five tests the highest and lowest percentages of water collected depart from the average percentage by more than 5 %, the series of five tests must be repeated. If within a second series of five tests the highest and lowest percentages of water recovered again depart from the average percentage by more than 5 %, and if the lower value does not satisfy the requirements of point 5.1, type-approval shall be refused.
5.3.Where the vertical position of the device influences the results obtained, the procedure described in points 4.1 to 4.4 must be repeated in the positions giving the highest and lowest percentages of water collected; the requirements of point 5.2 remain in force.
The requirement of point 5.1 remains in force in order to give the results of each test.
