1. Application: Apply non-water washable penetrant only to clean, dry surfaces by spraying, flowing, brushing or dipping.

2. Dwell Time: A 10-minute dwell time is suggested, although in many cases five minutes will suffice. When particularly tight cracks are suspected, or the part is especially critical, the dwell time may be extended to 30 minutes, or longer. Allow the penetrant to drain from the part surface back into the penetrant tank to conserve material.

3. Removal:

a. Immersion Method:

i. Pre-wash: Following the dwell use a plain water rinse to remove most of the undrained penetrant from the surface. Use coarse spray ambient temperature water.

ii. Immersion: Immerse and agitate the part in a 20 to 30% emulsifier solution. Immersion time and agitation will vary with part geometry and surface condition

iii. Rinse: Remove the part from the tank; clean with a course, plain water spray.

b. Spray Method:

i. Wash: Following the dwell, use an injection of 0.1 to 5.0% emulsifier solution to wash the excess penetrant from the part surface. Time and solution concentration will vary with part geometry and surface conditions.

ii. Rinse: Use a coarse plain water spray to remove all traces of the emulsified penetrant.

4. Drying: A re-circulating oven set no higher than 1600F (710C) is suggested. Leave the part in the oven just long enough to evaporate surface moisture. Drying is improved by using pressurized air to disperse and remove as much excess water as possible before placing the part into the oven.

5. Developing: Apply the developer by cloud dusting, spray or dip using the appropriate developer. Flaw marks are visible under appropriate lighting almost immediately but allow sufficient developing time to enhance the flaw visibility.

6. Inspection: Inspect parts under appropriate light.

3. Removal: Use the appropriate washing method to remove the excess penetrant from the surface

a. Emulsification: Following the dwell, dip the part into undiluted lipophilic emulsifier. Remove the part and allow the excess emulsifier to drain back into the tank. Parts with rough surfaces require longer drain times.

b. Rinse: Use a coarse plain water spray to remove all traces of the emulsified penetrant.

1. Application: Apply penetrant only to clean, dry surfaces by spraying, flowing, brushing or dipping.

2. Dwell Time: After application, allow the penetrant to drain from the part surface back into the penetrant tank to conserve material.

3. Removal: Remove as much excess penetrant as possible using clean, dry rag or towelling. Remove remaining penetrant film by wiping with a lint free rag or towelling that has been slightly moistened with DR-60. Use a minimal of DR-60; avoid flushing penetrant from flaws

4. Drying: Allow the surface to dry completely before applying developer.

5. Developing: Apply the developer by cloud, dusting, spray or dip using the appropriate developer. Flaw marks are visible under appropriate lighting almost immediately but allow sufficient developing time to enhance the flaw visibility.

Penetrant Process

1. Application: Apply penetrant only to clean, dry surfaces by spraying, flowing, brushing or dipping.

2. Dwell Time: After application, allow the penetrant to drain from the part surface back into the penetrant tank to conserve material.

3. Removal: Remove as much excess penetrant as possible using clean, dry rag or towelling. Remove remaining penetrant film by wiping with a lint free rag or towelling that has been slightly moistened with DR-64. Use a minimal of DR-64; avoid flushing penetrant from flaws. Do not spray DR-64 directly on the part surface when removing excess penetrant. Rough surfaces require more generous applications of DR-64.

4. Drying: Allow the surface to dry completely before applying developer.

5. Developing: Apply the developer by cloud, dusting, spray or dip using the appropriate developer. Flaw marks are visible under appropriate lighting almost immediately, but allow sufficient developing time to enhance the flaw visibility

6. Inspection: Inspect parts under appropriate light.

Magnetic Particle Process

1. Clean the test surface and allow it to dry.

2. The longer CP-2 is stirred or agitated the more uniform the spray.

3. Apply a thin coat of CP-2 to the inspection area from a distance of approximately 150mm from the surface.

4. Wait approximately 20 seconds, depending of ambient temperature, for the paint to dry.

5. Magnetise the area to be inspected.

6. Ensure continuous agitation of the suspension fluid. If using an aerosol, shake vigorously before and during inspection.

7. Apply the suspension to the test part.

8. Allow the excess oil/water to run off the inspection area.

9. Inspect the surface under visible light.

10. Collections of particles will reveal discontinuities at the leakage fields.

11. Clean and repeat the process, changing the orientation of the magnetising direction.

12. DR-64 can be used to remove CP-2 after the process is completed.
