3. INTRODUCTION
• Inspection and testing activities always involve the
evaluation of a characteristic as it relates to a specific
requirement.
• Inspection and testing functions can be done
automatically, manually, or both in a sequential
manner.

4. Interpretation of the
specification
Measurement of
the quality of the

5. TYPES OF INSPECTION
INSPECTION
Attribute
inspection.
Variable
inspection
Evaluation can be
determined by using the
intrinsic senses of the
human being (i.e., smell,
taste, sight, hearing, and
touch)
The inspection and testing
evaluation that is
determined by using any
measurement device e.g.
mechanical, electronic,
laser, chemical device

7. PURPOSE OF INSPECTION AND TEST
• The purpose of inspection and test is to determine the conformance of the product.
• The disposition of product based on the result of the evaluation.
• This determination involves three main decision

8. PURPOSE OF INSPECTION AND TEST
Conformance
decision:.
• To judge whether the product conforms to specification.
Fitness-for
use
decision::.
• To decide whether nonconforming product is fit for use
Communicati
on decision:.
• To decide what to communicate
to outsiders and insiders

9. INSPECTION PLANNING
• For each inspection station, the planner lists the quality
characteristics to be checked.
• To determine these, the planner considers the various sources of
pertinent product information.

10. INSPECTION PLANNING
• The needs of fitness for use
• The product and process specifications as published by the engineers
• The customer’s order, which references the product specification but may call for
modifications
• The applicable industry standards and other general-use sources

11. INSPECTION PLANNING
• For test stations, the planner must consider the functional and reliability parameters, such as
1. The industrial standards
2. Third-party requirements
3. Application environments
4. Customer expectations

12. SERIOUSNESS CLASSIFICATION
• Another way of identifying the vital few control subjects is
through "seriousness classification.”

13. SERIOUSNESS CLASSIFICATION
• Will surely cause an operating failure of the unit Will
surely cause
Class A: Very serious (demerit value,100)
•Will probably cause an operating failure of the unit in service that cannot
be readily corrected in the field, e.g., protective finish missing from coaxial
plug
• Will surely involve increased maintenance or decreased life, e.g., single
contact disk missing
Class B: Very serious
(demerit value,50)
•May possibly cause an operating failure of the unit in service, e.g., contact
follow less than minimum,
• Likely to involve increased maintenance or decreased life, e.g.,
dirty contac
Class C: Very serious
(demerit value,50)
•Will not affect operation, maintenance, or life of the unit in service (including
minor deviations from engineering requirements), e.g., sleeving too short, or
• Minor defects of appearance, finish, or workmanship, e.g., slightly scratched
finish.
Class D: Very serious
(demerit value,50)
