4.1 Gauge Checker test limits
The test limits set for the Gauge Checker have been derived
from the performance specifications quoted for the Equator and
the measurement uncertainty
†
evaluated for the inspection of the
Gauge Checker (to a 95% confidence interval).
• Size
1
: ± 2 µm
• Position
1
: ± 2 µm
• Distance:
• 1D
2
: ± 2.8 µm
• 2D
3
: ± 4.0 µm
• 3D
4
: ± 4.9 µm
• Form error
5
: 5 µm
• Freeform curve deviation
6
: ± 5 µm
Note: These limits have been set for the Golden Part
Comparison method, with no calibration file (.cal file), and with
an assumption of no more than 2 °C temperature difference
between master and measure.
