INTRODUCTIONInspection 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.

TYPES OF INSPECTION INSPECTIO

N

Attribute inspection

.

Evaluation can be determined by using the intrinsic senses of

thehuman being (i.e., smell, taste, sight, hearing, and touch)

Variable inspection

The inspection and testing evaluation that is

determined by using any measurement device e.g. mechanical, electronic, laser, chemical device

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

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

Communication

decision: •To decide what to communicate to outsiders and insiders

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.

INSPECTION PLANNING The needs of fitness for useThe 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

consider the functional and reliability parameters, such as_

SERIOUSNESS CLASSIFICATIONAnother way of identifying the vital

few control subjects is through "seriousness classification.”

05/02/2023 13

SERIOUSNESS CLASSIFICATION

Class A: Very serious

(demerit value, 100)

•Will surely cause an operating failure of the unit•Will surely cause intermittent trouble, difficult to locate in the

field, e.g., loose connection

Class B: Serious (demerit

value, 50)

•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 C: Moderately

serious (demerit value,

10)

•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 D: Not serious

(demerit value, 1)

•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.
