Holiday Detection
Holiday Detection, also known as continuity testing, is a non-destructive method used to identify discontinuities like pinholes and voids in protective coatings.
By checking the flow of electric current, this test ensures the integrity of coatings applied to tank interiors, chemical storage vessels, and buried structures. Detecting these minute flaws is crucial for maintaining effective protection in aggressive environments. Holiday detection is a key practice in ensuring that coatings perform their intended protective function, preventing potential failures and prolonging the lifespan of the coated materials.
