When are METAL

TESTINGS Used ?

To assist in product development

To screen or sort incoming materials

To monitor, improve or control manufacturing processes

To verify proper processing such as heat treating

To verify proper assembly

To inspect for in-service damage (NDT)

Failure Analysis

7

Why are metals tested ?

Ensure quality

Test properties

Prevent failure in use

Make informed choices in using materials

Factor of Safety is the ratio comparing the

actual stress on a material and the safe

useable stress.

8

Two forms of testing

Mechanical tests the material may be physically tested to destruction. Will

normally specify a value for properties

such as strength, hardness, toughness,etc

Non-destructive tests (NDT) samples or finished articles are tested before or being

used.
