The qualification shall consist of using one specific plating solution on one base metal as designated in generic groups below.
a. Aluminum and its alloys b. Chromium plated parts
c. Copper and its alloys except aluminum bronze d. Low carbon steel
e. Medium carbon or high strength steels f. Cast iron
g. Nickel and its alloys h. Zinc
i. Aluminum bronze
J. Martensitic stainless steel k. Austenitic stainless steel
Regardless of base metal used for qualification, it will qualify all base metals in that specific generic group for the type of plating applied. The test plates accomplished for procedure qualification may also be used to meet the practical examination in 4.4.2.2.2. Revisions to procedures other than editorial or administrative shall require requalification in accordance with this standard prior to use.
4.4.1.1 Specimens needed to qualify.
4.4.1.1.1 Manual application procedure. Specimens for qualification of procedures where the plated layer is applied manually shall be strips of metal approximately 5 inches long by 1 inch wide by 0.050 inch thick. When the procedure is used to fill defects, the strip shall contain a groove 0.0625 inch wide by 0.010 inch deep by 1 inch long. The length dimension of the groove shall coincide with the length direction of the strip and be centered on it.
