GENERAL INFORMATIONThe information given below is provided for clarification and assistancein meeting the
32、requirements of this specification.5.1 Car Wash Spray No loss in adhesion, li fting, filmcra cking, pitting, or color andgloss changeTest Method: Use a car wash unit with a 1100 psi (76 bars) minimumpressure at gun tip, a maximum or 15 degree gun tip fan angle, and awater temperature of 23 +/- 2 C. At a distance of 200 mm from sampleat a 45 degree angle of the sample to the water spray, spray waterfor a five minute duration on the sample edge. Remove spray andexamine sample.
