Weights & Measures

Weights & Measures
Quick packer checks using the UK “3 packer rules” (Average, TNE, and Maximum Error).

3 packer rules

  • Average Quantity Rule: On average, the actual contents (weight or volume) of all packages in a batch must equal or exceed the nominal quantity stated on the label.
  • Tolerable Negative Error (TNE) Rule: Only a small percentage of packages in a batch are allowed to be slightly underweight (below the nominal quantity by a defined amount called the Tolerable Negative Error, or TNE).
  • Maximum Error Rule: No single package can be underweight by more than twice the Tolerable Negative Error (TNE).

SG Cup Calibration

SG Cup Calibration
Calibrate an SG cup using water density vs temperature, check tolerance (PASS / FAIL), and generate a correction factor.
Actual volume = weight ÷ water density. PASS if |deviation %| ≤ tolerance.
