ACCEPTABLE QUALITY LIMITS
A concept used with sampling procedures applied to arms-ammunition suppliers during
World War II, AQL is the  POOREST QUALITY that a supplier can provide and still be
considered 'acceptable' or satisfactory.  The concept  -that some errors or defects are
normal-is the antithesis of 'zero defects,' which holds that the only allowable
standard for quality is error-free work.

ACCEPTANCE NUMBER
The maximum number of non-conforming items allowable in a sample for the purpose of acceptance.

ACCEPTABLE QUALITY LEVEL
The quality level approved for outgoing product. It is the worst quality, as a percent of non-conforming items,
that would still be considered acceptable.

ACCEPTANCE SAMPLING
A system by which a lot is accepted or rejected based on the result of inspecting samples from the lot.

ACTIVATION
Elimination of passive condition on the cathode surface to promote deposit adhesion.

ACCURACY
The degree to which the mean of a series of measurements differs from the value.

ADDITIVE
A chemical added to a plating bath to improve its plating current density, brighten and/or improve other deposit characteristics.

ANODE
The positive electrode in the tank, in which the soluble anodes are dissolved to replenish the metal being plated.
The electrode at which oxygen is discharged.

ANODE BAG
The polypropylene bags are used to contain the anodes. It prevents dissolved particles during electrolysis from
entering the solition and codepositing onto the part.

ANODE EFFICIENCY
The actual weight of metal dissolved divided by the theoretical weight of anode that should be dissolved during eletrolysis.

ANODIC CLEANING
Electrocleaning the part at a positive voltage. Also called reverse cleaning. The oxygen discharged tens to passivate the part.

ANODIC TERMINAL
Positively charged  (+) terminal of the rectifier to which the metal to be dissolved is attached;
also see INSOLUBLE anodes.

ASQC
The American Society for Quality Control, located in Milwaukee, Wisconsin, United States.
With the industrial fury that   World War II engendered, and life -or-death necessity of decent product quality, the profession took another major forward.  The sudden increase of inspectors and quality engineers resulted in the formation of an academic and professional  society to further the spread of quality techniques and technologies.  This group, formally established in 1945, was originally  called the SOCIETY for QUALITY ENGINEERS.  Today we know it as the American Society for Quality Control ( ASQC ).  Its creation went a long way  toward legitimizing quality control as an integral part of the industrial scene.
