ff erent control levels:
one measurement of each control exceeds the same limit.
The run is judged to be OUT OF CONTROL.
R
4s
The range between the high and low control measurements within a run exceeds 4s. This
rule is sensitive to random errors.
This rule is applied on the same control level and on di
ff erent control levels: one
measurement exceeds the +2s limit and the other exceeds the -2s limit.
The run is judged to be OUT OF CONTROL.
4
1s
4 consecutive control measurements within or across a run exceeds the same limit, either x
- 1s or x + 1s. This rule is sensitive to systematic errors.
This rule is applied on the same control level or on di
ff erent control levels:
4 consecutive measurements across control levels exceed the same limit,
either x - 1s or x + 1s.
The run is judged to be OUT OF CONTROL.
10
x
10 consecutive control measurements fall on one side of the mean. This rule is sensitive to
systematic errors.
This rule is applied on the same control level or on di
ff erent control levels
The run is judged to be OUT OF CONTROL.
