 Gauge R&R study


Gauge R&R type 1

Type 1 tests are simple repeatability trials with one operator, one part and multiple repetitions. Results show gauge repeatability.

Test conditions Type 1

Gauging cycle time48 sec

Gauge R&R type 2

Gauge R&R type 2 tests involve multiple operators, multiple parts and multiple repetitions. Results give an indication of real world conditions, including factors such as gauge repeatability, fixture distortion and operator inconsistencies.
