Product Code:SAE AMS2646
Title:Contrast Dye Penetrant Inspection (Cancelled Apr 1999, Superseded by ASTM E 1220)
Issuing Committee:Ams K Non Destructive Methods And Processes Committee
Scope:Detection of discontinuities such as cracks, laps, porosity, cold shuts, lack of bond, and similar defects. Because inspection can be performed in normal light, this method can be used when fluorescent penetrant inspection is impracticable.【英文标准名称】:Practiceforuseofapolymethylmethacrylatedosimetrysystem
