The purpose of this test is to verify part marking validity of the electronic component part when subjected to solvents as seen in many cases in the growing epidemic of counterfeit components. Various Military Standard procedures are utilized which incorporate processes of working with several chemicals mixed appropriately and in detail in accordance with the specifications. These chemicals consist of Aliphatic alcohol, mineral spirits, ethyl-benzene, organic solvents, de-ionized water, propylene glycol monomethyl either, or monoethanloamine. “This has been a very successful process in uncovering non authentic marking on ceramic package electronic components as well as certain plastic, can or glassivated component package devices” said NJMET VP Joseph Federico headquartered in Clifton, NJ. Once properly mixed the components are submerged in a three phase process and analyzed in accordance with MIL-HBK-130 to uncover evidence of damage to the device and any specified markings which are missing in whole or in part, faded, smeared, blurred, or shifted (dislodged) to the extent that they cannot be readily identified from a distance of at least 15.0cm (6inches) with normal room lighting and with out the aid of magnification or with a viewer having a magnification no greater than 3X shall constitute a failure.
