Ultraviolet Light Inspection
Inspection & Testing
Ultraviolet Light Inspection
Ensure absolute surface purity and complete degreasing with Fortune Seven’s specialized UV black light inspection services.
High-Sensitivity Organic Screening:
Utilizes ultraviolet light to trigger fluorescence in invisible trace oils, greases, and heavy hydrocarbons.
Standard-Aligned Execution:
Conducted according to the black light inspection procedures set out in ASTM A380.
Passivation Efficiency Support:
Eliminates oil barriers that prevent passive film formation and cause patchy corrosion protection.
Complementary QA Testing:
Works alongside ASTM A967 free-iron validation tests (such as Ferroxyl and Oxilyzer) for 100% surface quality assurance.
