Application Summary AI generated

This standard specifies the pulsed eddy current testing method for detecting surface and subsurface defects in non-ferromagnetic metallic components, such as aluminum, copper, and titanium alloys. It is applied in industries like aerospace, automotive, and power generation for in-service inspection of conductive materials, particularly where conventional eddy current techniques are limited by lift-off or coating effects. The method is used to evaluate corrosion, cracks, and thickness variations in structures like aircraft skins, pipelines, and pressure vessels.
