The accuracy is the degree of closeness of the measured value to its "true" value. This value is generally diffined as a purcentage of the capacity of the sensor or instrument in the unit of measurement. For example, on our Centor Easy force gauge withinternal sensor, the accuracy is 0.1% FS.
It means that if you have a sensor with a capacity of 100N, the accuracy of the complete gauge is 0.1% of 100N = 0.1N.
You can find this value with different spelling: 0.1%, 0.1% of the full scale, 0.1% FS (FS: Full scale), or 0.1N.

Breaking load or force

The breaking load is the force required to break or to cause fracture during a tension, compression or torsion test. In thin and non-eleastical material (wire, sheet metal), it is most of the time the peak force because it is difficult to distinguish the break force from the peak force.
In textiles and yarns industries the breaking force or load is commonly called breaking strength reported in lb/in.

Climbing drum peel test - ASTM D1781

This test method covers the determination of the peel resistance of adhesive bonds between: a relatively flexible adherend and a rigid adherend; and the relatively flexible facing of a sandwich structure and its core, when tested under specified conditions.

Load cell

A load cell is a device which produces an Output signal proportional to the applied weight or force.[/en] A device which produces an Output signal proportional to the applied weight or force.

Pull Testers

A mechanical hydraulic fluid based test instrument used to provide a means of determining whether a particular mechanical fastener provides sufficient resistance to static uplift force to meet the wind-load requirements.
Testing instrument used for a Quality Assurance Test and it is required for verifying adhesion of the newly installed or renovated building envelope systems.

Spring ratio

An extension or compression spring has units of force divided by distance, for example lbf/in or N/m. A spring is an elastic object used to store mechanical energy. When a spring is compressed or stretched, the force it exerts is proportional to its change in length. The rate or spring constant of a spring is the change in the force it exerts, divided by the change in deflection of the spring.
