Callington Calcheck WCP

These instructions describe the basic process, but they may need to be amended by the user to comply with applicable specifications and/or inspection criteria provided by the contracting agency. 1.Clean the test surface and allow it to dry. 2. The longer WCP is stirred or agitated the more uniform the spray. 3.Apply a thin coat of WCP contrast paint to the inspection area sprayed from approximately 150mm from the surface. 4.Wait approximately 20 seconds, depending on 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.
