List of data for internal criteria
Internal control Internal control criteria on / off
Sample quantity Sample quantity value for a product
Error value [- T]
Error value of marginal negative T (-T) given
in unit of product nominal mass Qn.
Measurements lower than value of Qn-T are
regarded as valid.
Error value [+ T]
Error value of marginal positive T (+T) given
in unit of product nominal mass Qn.
Measurements higher than value of Qn+T are
regarded as valid.
Quantity of smaple
[Qn-2T] dis.
Number of negative errors (–2T) of a tested
sample which disqualifies control
Quantity of smaple
[Qn+2T] dis.
Number of positive errors (+2T) of a tested
sample which disqualifies control
Quantity of smaple
[Qn-T] dis.
Number of negative errors (–T) of a tested
sample which disqualifies control
Quantity of smaple
[Qn+T] dis.
Number of positive errors (+T) of a tested
sample which disqualifies control
Average limit value
Mode for estimation of average limit value
(constant or automatic)
Average limit value - Value of average limit (negative) of a tested
sample (concerns value of average limit as
“constant”)
Average limit value + Value of average limit (positive) of a tested
sample (concerns value of average limit as
“constant”)
Factor value [-Wk]
Multiplier of standard deviation for value of
average limit (negative) calculated
automatically
Factor value [+Wk]
Multiplier of standard deviation for value of
average limit (positive) calculated
automatically
