PARIS CONVENTION FOR THE PREVENTION OF MARINE POLLUTION
(Vilfredo); Italian economist dubbed 'Father Of Modern Fascism' for his views on elitist ruling classes;
( also see '80:20 Rule' ).
A system of analysis based on the principle that, in any phenomenon, relatively few factors
account for the majority of effects. Juran uses the phrase 'vital few' to suggest that it is
more efficient and less costly to concentrate on the most important sources or types of failures,
customers and so on.
1.) Pareto analysis is a way of organizing data to show what major factor(s) make up the subject
being analyzed. It is a search for significance. 2.) A Pareto Chart is a type of chart in which the
bars are arranged, in descending order, from the left. 3.) The basis for Pareto analysis is the '80:20: rule.
For instance, 80% of the problems result from 20% of the cause.
The condition of metal such that it assumes a potential more noble than its standard potential.
Plating onto a passive surface results in poor adhesion.

POWDER COATING INSTITUTE
PRODUCT DATA EXCHANGES
PERMISSIBLE EXPOSURE LIMITS
The detachment of a deposit from the basis metal or from the preceding deposit.
The ability of a sequestering agent to hold suspended particles in a bath and form a colloidal dispersion.
POLLUTION EMISSIONS REGISTER
A counting technique that requires the ordered arrangement of a set of objects.
PROGRAM EVALUATION AND REVIEW TECHNIQUE
A scale for defining the acidity or alkalinity of a bath; the more hydrogen
(H+) ions the lower the pH; the more hydroxide (OH-) ions the higher the pH;
than 5 or less = ACID 9 or more = AKALINE 6 to 8 = NEUTRAL.
PROCESS HAZARD ANALYSIS
Metal phosphate in phosphoric acid will lightly pickle base metal causing the zinc
phosphate and base metal to combine forming a gray film.
PROCESS HAZARDS REVIEW
PRIOR INFORMED CONSENT
The removal of oxides, heat scale or other compounds from a part by immersion in acid dip or by electrolysis.
A pie chart is a graphic representation which compares the relative magnitudes
or frequencies of things. Useful for more than one level of stratification: all on one
graph, equivalent to several bar charts. Shows relative proportion of each category to the whole.

POWDER INJECTION MOLDING
PRODUCT IDENTIFICATION NUMBER
PIN HOLE BLEEDING
Bleeding of trapped chemicals from porous deposit or coating (not necessarily related to chemical attack of the part).
The depression produced in the deposit by non-uniform electrodeposition or defects on the part.
PROGRAMMED LOGIC CONTROLLERS

PARTICULATE MATTER; POWDER METALLURGY
PRECISION METALFORMING ASSOCIATION
PLASTIC MEDIA BLASTING
POLYMER MATRIX COMPOSITES
PACIFIC MATERIALS EXCHANGE
POWDER METAL INDUSTRIES FEDERATION
The change in electrode potential during electrolysis, such that potential of the anode becomes nobler,
and the applied current continuously drops.
PERFORMANCE-ORIENTED PACKING STANDARDS
The total set of observations being considered in a statistical procedure.
A tiny cavity or channel extending completely or partly through the deposit to the basis metal.
The presence of tiny pores of meniscus cavities in the deposit.

PRACTICAL QUANTIFICATION LIMIT
The degree to which the results of a series of repeated measurements on the same item are in agreement.
Those steps which the base metal must undergo before plating including STRIKE
ZINCATE or FLASH to make the raw base metal active and plateable.
Those steps which base metals must undergo before plating; included can be
PRE-CLEANING CLEANING and PRE-PLATING to 'make-ready' raw parts.
Th e scientific approach of controlling all manufacturing PROCEESSES rather than
the product made by them. The logic is to find which VARIABLES 'cause' any
given product CHARACTERISTIC and to control these VARIABLES instead of the product.
PERFORMANCE REVIEW INSTITUTE
The mathematical calculation of the likelihood that an event will occur.
The ability of a process to meet operating goals or internal- or external-customer requirements.
'CAPABILITY' may differ from actual performance due to 'special cause'-conditions
or events due purely to chance and not to the production system itself.
PROCESS FLOW DIAGRAMMING
A visual systematic way of examining a process by diagramming all its inputs outputs and activities.
