                                               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.
