criteria
Quantity of a product sample
Value of negative permissible error –T, set in
a weighing unit determined for the product.
Measurements below the Qn-T value will
be comprehended as defective.
Value of positive permissible error +T set in
a weighing unit determined for the product.
Measurements above the Qn+T value will
be comprehended as defective.
Number of recorded negative errors -2T in
a tested sample that disqualifies a control
Number of recorded positive errors +2T in
a tested sample that disqualifies a control
Number of recorded negative errors -T in
a tested sample that disqualifies a control
Number of recorded positive errors +T in
a tested sample that disqualifies a control
Mode for calculating the average limit value
(constant or automatic)
Average limit value (negative) for a tested
sample (refers to average limit value as a
"constant")
Average limit value (positive) for a tested
sample (refers to average limit value as a
"constant")
Standard deviation multiplier for the average
limit value (negative) determined in the
automatic mode
Standard deviation multiplier for the average
limit value (positive) determined in the
automatic mode
