Principles of liquid penetrant inspection
1. Temperature control
2. Penetrant quality control
3. Dwell quality control
4. Emulsifier path quality control
5. Wash quality control
6. Drying process quality control
7. Developer quality control
The temperature used to dry parts after the application of
an aqueous wet developer or prior to the application of a
dry powder or a non-aqueous wet developer, must be
controlled to prevent drying in the penetrant in the flaw.
