USP 1251的指导原则:
Property——Sensitivity
Definition—— Change in the displayed value divided by the load on the balance that causes the change.
Details——①The testweight is suit able if it has a nominal mass of 5%-100% of the balance's capacity.
②A test weight close to the balance's capacity will more effectively identify the deviation due to sensitivity.
Acceptance Cretira——①NMT 0.05% deviation from 1 (the sensitivity of a correctly adjusted balance, i.e., displayed value = load value), where <41>is applicable.
②For other uses, respective tolerance requirement divided by 2.
