6. Anticipating risk with minimum weighing
Minimum weighing is the smallest amount of sample required for a weighing operation to be consistent with a specific relative weighing accuracy.
Consequently, when weighing a quantity representing a minimum weighing, P min , the relative measurement uncertainty of the weighing is equal to the required weighing accuracy, Need, so that U(P min )/P min = Need. This yields the equation (9) which is used to determine the minimum weight:
