This test method provides the capabilities, limitations, and suggested possible applications of TGA as it pertains to the detection of counterfeit electronic components. Additionally, this document outlines requirements associated with the application of TGA including: equipment requirements, test sample requirements, methodology, control and calibration, data analysis, reporting, and qualification and certification. If AS6171/10 is invoked in the contract, the base document, AS6171 General Requirements shall also apply.

The intent of this document is to define the methodology for suspect parts inspection using radiological inspection. The purpose of radiology for suspect counterfeit part inspection is to detect deliberate misrepresentation of a part, either at the part distributor or original equipment manufacturer (OEM) level. Radiological inspection can also potentially detect unintentional damage to the part resulting from improper removal of part from assemblies, which may include, but not limited to, prolonged elevated temperature exposure during desoldering operations or mechanical stresses during removal. Radiological inspection of electronics includes film radiography and filmless radiography such as digital radiography (DR), real time radiography (RTR), and computed tomography (CT). Radiology is an important tool used in part verification of microelectronic devices.
