Marking Permanency Test
MPT
|
External visual inspection may reveal evidence of remarking where the original marking was removed by chemical or mechanical means, and the marking area was resurfaced or masked with a material that may or may not match the original surface. Any removal of the original surface finish, laser markings, or ink markings is an indication the part may be fraudulent or counterfeit. This first test focuses on ink part markings and is a modified resistance-to-solvents test. To perform this test, mix a solution of three (3) parts mineral spirits (CAS Registry Number 9072-35-9) with one (1) part isopropyl alcohol (CAS Registry Number: 67-63-0). Dip a cotton swab into the solution, and wipe the swab across the markings on the part. The markings should not smear or be removed by the solution. However, more agressive test methods that will also test for resurfacing reveal other indications that the original device marking has been removed. |

Microblasting
|
The process of microblasting uses a very fine abrasive media at 10 to 50 micron size which is then propelled through a fine-tip nozzle. This is used to texture or cut through materials where exacting detail is required. See also Sandblasting and Relabeling. |

Military Screening
|
Military systems often need product which will perform beyond the standard data sheet specifications. To satisfy this need, standard product is screened to military specifications. Upon successful completion of the screening, the parts are marked to a special part designation and are generally sold at a much higher price than the standard part. |
