What needs to be clarified
Review content determination and recalculate results, considering tare, label units, balance suitability and grounds for extending conclusions to the identified bottle lot.
Materials to prepare
- Bottles with intact labels linked to sampling records
- Full weighing protocol identifying balance and each pack
- Tare, dispenser and empty-bottle cleaning information
What to compare
Match the declared quantity to the measured one; check zero records, resolution and weighing conditions. Determine tare appropriately, considering residues and component variation. Preserve gross readings and net calculations for every sample. Review sampling and comparison criteria without replacing variability data with one average empty-bottle mass.
Possible outcome of the analysis
The review may provide a corrected content table, methodological limitations and an assessment of which report claims the original measurements support and which require resampling.
Limits of the conclusions
Mass is not volume without justified density data. Quantity-marking checks do not establish composition or product quality; one bottle cannot represent an entire heterogeneous delivery.
