Non-destructive testing. Thermographic testing. Active thermography1 Scope This document defines the procedures for non destructive testing using active thermography. These testing procedures can be applied to different materials (e. g. composites, metals and coatings) and are appointed, but not limited to the: detection of discontinuities (e. g. voids, cracks, inclusions, delaminations); determination of layer or part thicknesses; determination and comparison of thermophysical properties. This standard is describing
