Scrape abrasion is a useful test for aviation wiring, although liable to inherent variability in test data. Thus, the results should be considered as a general assessment rather than a specific time to failure. Variability in the wire, cable, and wire harness construction will impact the test performance. In this Lectromec article, we examine how these factors impact scrape abrasion results and the value of such results when such variability is inevitable. Read more
