EVALUATION OF DIRT FILMS, LAMPS AND PROCEDURES FOR HEADLAMP WASHER TESTS

Four dirt film formulations were evaluated for use in testing of headlamp washers. The evaluations were made using three different headlamp beam patterns and four different sets of photometric test points. From these tests, a test dirt film, a test lamp and a set of photometric test points were selected which were judged to be internationally acceptable for testing headlamp washers. Recommended revisions to the Docket 69-19 washer standards were prepared.
