TEST METHOD STANDARD METHOD 209, RADIOGRAPHIC INSPECTION
|Publication Date:||6 September 2019|
Radiographic inspection is generally a nondestructive (see 1.2) method for detecting internal physical defects in small component parts which are not otherwise visible. Radiographic techniques are intended to reveal such flaws as improper positioning of elements, voids in encapsulating or potting compounds, inhomogeneities in materials, presence of foreign materials, broken elements, etc.
NOTE: For certain device types, opacity of the construction materials (packages or internal attachment) may effectively prevent radiographic identification of certain types of defects from some or all possible viewing angles. This factor should be considered in relation to the design of each device when application of this test method is specified.
Radiographic inspection may be performed on most parts; however, radiation may cause changes in electrical behavior of some materials.
