1. Application: Apply fluorescent 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: Use the appropriate washing method to remove the excess penetrant from the surface

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: A dust chamber is a practical method for applying D-90G. D-90G can also be applied with electrostatic spray, low pressure spray wand, or a hand powder bulb. D90G may also be applied by immersing the part directly in the developer powder. (Never re-immerse the part in developer as re-immersion can wipe away penetrant already drawn to the surface.) Shake or use very light air pressure to blow the excess D-90G powder from the surface. Allow a minimum of ten minutes. Developing time for especially critical inspections, lengthen the developing time.

6. Inspection: Inspect parts under appropriate UV-A light intensity and minimal visible light.

4. Developing: After agitating the D-106 suspension, evenly spray a light slightly wet coasting of developer onto the dry surface of a part. An overly wet application lacks full developing action. Two or three light applications work better than a single heavy application. Too heavy an application may conceal indications. If D-106 is to be applied with a paint spray gun, the spray gun should have a vaporizing tip, the spray tank should be pressurized to 15-30 pounds of pressure and have a stirrer to keep the powder in suspension.

5. Inspection: Inspect parts under appropriate light intensity.

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

4. Drying:

a) A re-circulating oven set no higher than 71ºC is suggested. Leave the part in the oven just long enough to evaporate surface moisture. Drying is improved by using pressurised air to disperse and remove as much excess water as possible before placing the part into the oven

b) When solvent remover is used, allow the surface to dry completely before applying developer.

5. Developing: After agitating the D-100 suspension, evenly spray a light slightly wet coating of developer onto the dry surface of a part. An overly wet application will blur indications; an overly dry application lacks full developing action. Two or three light applications work better than a single heavy application. Too heavy an application may conceal indications. If D-100 is to be applied with a paint spray gun, the spray gun should have a vaporising tip, the spray tank should be pressurised to 15-30 pounds of pressure and have a stirrer to keep the powder in suspension.
