The WATER BREAK TEST
Also recognised as ASTM-F-22
This test is probably one of the most important procedures in any plating or anodizing operation.
Make sure you carry out this test after doing all the preparation work, including degreasing and etching in pickles.
To pass the test water will sheet off the part rather than bead off.
Alternatively, apply several drops of distilled water to the cleaned surfaces. If the surface is inadequately cleaned, the spherical form of the drop is largely retained, and the surface must be cleaned once more. If the water runs on the treated surface, then wetting has been satisfactory and the part is ready for plating.
