UV / NDT Lights

Inspection lights for Weld Testing and finding Hydrocarbons on steel. UV and Bluelights, Regular and Explosion-Proof.

ASTM A-380 Standard Practice for Cleaning, Descaling, and Passivation of Stainless Steel Parts, Equipment, and Systems contains specific details on use of black light for surface inspection:  7.3.2 "Black Light Inspection is a test suitable for the detection of certain oil films and other transparent films that are not detectable under white light. In an area that is blacked out to white light, inspect all visible accessible surfaces with the aid of a new, flood-type, ultraviolet lamp." However, ASTM A-380 also indicates that "The test will not detect straight-chain hydrocarbons such as mineral oils." Use of Black Light for inspection of surface preparation is a useful tool and can be a required step for certain industries.
