SAE AIR4090

Description / Abstract: This report describes basic methods, typical results, limitations, and technical variables which may provide some relative performance expectations for different lots of the same material, or comparison characteristics for different materials. This testing alone does not assure satisfactory operation in the engine, i.e., there is not a direct relationship to actual engine performance.

Purpose:

This report provides specific information on procedures for evaluating, on an accelerated comparison basis, the durability of ceramic materials under conditions of compressed electrical (capacitor) discharge.
