Below mention is surface preparation for test specimen:

• Surface should be free from foreign matter which prevents penetration
• Dust and dirt can be removed using a piece of cloth
• Rust, paint & wax must remove from the testing surface using wire brush
• Grease and oil must remove from the surface using PMC Cleaner

 

Application of Penetrant:

• The PMC penetrant is applied by dipping, spraying or brushing, keeping in mind that the surface areas are covered adequately. For penetration into defects, a 5 to 10 minutes time is sufficient (penetrant dwell time). Moreover, optimum period can be ascertained by trial only
• Excess Penetrant must be removed from the Testing Surface using a piece of clean cloth or absorbent paper

Following are the methods of removing excess penetrant from test surface in special cases:

• Use water spray if penetrant is water washable type
• Use cloth or absorbent paper moistened with solvent if penetrant is solvent removable base
• Use emulsifier for emulsifying penetrant and water spray if it is a post-emulsifying penetrant

Application of Developer:

• It has to be applied as soon as possible, after removal of excess penetrant from the test surface

Following are the applications of a developer:

• Wet developer should be used with color contrast penetrant
• Wet or dry developer may be used with fluorescent penetrant
