Status Report on Applications and Supplemental Requirements 680177
The author reviews work underway to expand current brake test standards. Initially he discusses the Pennsylvania procedure for testing original equipment and aftermarket brake linings. Although these tests are similar to SAE tests, current SAE procedures have to be expanded so they can be used for component approval, other than linings, in order to realize full capabilities of existing brake test specifications.
Subcommittee 7 has assigned working groups to develop special procedures in the areas of partial system performance, passenger car durability, brake structural integrity test, truck-trailer performance test, and car-trailer performance test. The work being done in these areas is reviewed.
It is obvious that constant up-dating of specifications is a necessity in order to reflect the state-of-the-art as accurately as possible.
