Resistance to Solvents

Resistance to Solvents is a testing method used to determine the validity of ink-printed markings and the physical surface of a component by using liquid solvents.

Part markings are tested using a mixture of alcohol and mineral spirits in accordance with industry standards. This process  removes the majority of painted and printed counterfeit markings, but has no effect on laser etched factory markings. There are occurrences when part markings suffer a high likelihood of removal regardless of being factory produced or counterfeit. Thus, this method is not used to test markings printed on metal. This exception, though immune to this type of testing, still undergo additional analysis to secure genuineness.

The physical surface of a component is tested using acetone (dimethylketone). Acetone facilitates the removal of resurface material from the surface of a counterfeit component. This portion of the process is strictly reserved for testing resurfaced material as acetone will result in the removal of some factory markings.
