Chapter 16
C. Inspection Planning
and Procedures
Part III.C.1
INTRODUCTION
Inspection is the evaluation of product quality by comparing the results of
measuring one or several product characteristics with applicable standards. From
this definition it is evident that the inspection function involves a number of tasks
(Raz 1992):
1. Measurement, which could be on a qualitative or quantitative scale.
The objective is to make a judgement about a product’s conformance
to specifications.
2. Comparison of the measurement results to certain standards that reflect
the intended use of the product by the customer and the various
production costs. If the product is found to be nonconforming, a decision
as to whether nonconforming products are fit for use may be reached.
3. Decision making regarding the disposition of the unit inspected, and,
under sampling inspection, regarding the lot from which the sample
was drawn.
4. Corrective action(s) in order to improve the quality of the product
and/or process based on the aggregate results of inspection over a
number of units.
Inspection decisions for most products are shown in Figure 16.1.
