unless otherwise specified
Procedure
When the paint adhesion test is required after another test procedure, the adhesion test must b
performed within 30 minutes of the previous test or as otherwise specified by the applicable
Engineering Material Specification
Measure and record film thickness, prior to adhesion test in accordance with FLTM B 117-01
Remove all loose debris( brush off)from the scribe line prior to tape test
Method -Scratch Test
On an unmarked section of the test panel, draw the knife blade across the panel for a distance of
50 mm with sufficient pressure to remove a narrow ribbon of paint down to the base metal. The flat
part of the blade should be inclined away from the operator at an angle of approximately 30 to the
panel and drawn towards him/her to remove the ribbon of paint
Examine and report any flaking or chipping or paint away from the scratch marks
