ASTM E3045-21

1.1?PurposeThis practice covers procedures required to conduct an examination of components using vibroacoustic thermography.

1.2?ApplicationThe vibroacoustic thermography process has been used for component inspections in the aircraft, power generation, automotive, and other industries for testing new and serviced components, both coated and uncoated. Current applications are mostly targeting metallic components, but composite and ceramic component applications are under development (1.3?BackgroundVibroacoustic thermography is a new technique within the area of active thermography. The technique was first published by Henneke, et al. in 1979 (2) and has been expanded on and popularized by Favro, et al. (Note 1:?Vibroacoustic thermography is typically sensitive to tight planar defects (Note 2:?Vibroacoustic thermography is a surface examination but has demonstrated detection sensitivity for subsurface defects including back wall defects for thin components (5), (6). Care should be taken when developing vibroacoustic thermography for the detection of subsurface defects.
