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.

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.

One of the three evaluative dimensions used in Baldridge scoring,
'approach' refers to the methods

and prevention based.

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.
