Purpose. This document outlines a method for determining the weight (and size or size distribution, if specified) of foreign material (e.g., sand, machining chips, blasting media, etc.) retained in or on any component after the final washing operation in the partial and/or finish machining process.

Foreword. This method involves washing components with a fluid, collecting the fluid, filtering the solid materials from it, and determining the weight (and size or size distribution, if specified) of the solids present.

Applicability. This method may be used to quantify foreign material present in or on engine and transmission components, including sub-assemblies and assemblies.
