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.

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.
