Abstract
Establishment of a new quality control (QC) test involves four phases. Development of an integrated set of QC tests for automotive brake linings (Phase I) was reported earlier. In a continuation of Phase I on differential thermal analysis (DTA), it was found that temperatures of some DTA peaks for linings are pressure-sensitive. Hence, good pressure control is necessary in using this test. It was also found that DTA gives useful information on the state of lining binder cure. A statistical test plan for rapid estimation of natural process limits (Phase II) is described and illustrated with DTA data.
