Because they are precise, yes, No, may be both, weights either they are of lowest accuracy in milligrams or of highest accuracy in few microgram, may be of critical use in their respective area of application.
After calibration a weight is defined with a value, any drastic change to their mass values may cause error in calibration or weighing process. A simple slip from the hand or ruff use may cause a weight going out of accuracy and continue using such weights will cause error in weighing.
Correct handling of weights is must to achieve best results and to ensure accuracy of the weights for long term.
