Force gauge
Test units of force measurements are most commonly newtons or pounds. The peak force is the most common result in force testing applications. It is used to determine if a part is good or not. Some examples of force measurement: door latch, quality of spring, wire testing, strength ... but more complicated tests can be performed like peeling, friction, texture.
Kip (unit)
The name comes from combining the words "kilo" and "pound"; it is occasionally called a "kilopound". Its symbol is kip, or less frequently, klb. When it is necessary to clearly distinguish it as a unit of force rather than mass, it is sometimes called the "kip-force" (symbol kipf or klbf).
Note that the symbol kp usually stands for a different unit of force, the "kilopond" or kilogram-force used primarily in Europe prior to the introduction of SI units.
