Holiday Test video or hole detection of coating

Holiday test or a Continuity test is one of the non destructive test method applied on protective coatings to detect unacceptable discontinuities such as pinholes and voids. The holiday detection procedure involves checking of an electric circuit to see if current flows to complete the electrical circuit.
Sometimes this test also called or refers metal detecting test of pipeline.
Holiday Detector - Premature corrosion of a substrate is usually due to a coating failure. A major cause is the presence of flaws in the finished coating, collectively referred to as porosity. Holiday test is used to detect holes, known as holidays or discontinuities, in a coating.
Pipeline holiday test standard during NLPG project at Mongla, Bangladesh.

It's Bangladesh not India

[@shaikasmathulla4068]

Holiday test will do with 15 KV( Per1mm /5 KV) , but testing doing person don't wear any PPE , it is hazardous situation

[@AllAroundMeExclusive]

May be they are using 32 KV. And the electric shock is strong enough to make you weak. Very hazardous situation.

[@tariqueahsan3887]

Above 25kv bro.
