INTRODUCTION
Millions of weighing operations are carried out every day. They are carried out in all industrial sectors, as well as in laboratories. Bodies weighed come in a variety of forms: liquids, solids, powders, metals, stones, plastics...
The challenge now is to determine whether the combination of balance uncertainty and measurement error could jeopardize the balance used, the measurement process in which it is integrated, and therefore the quality of the products, as well as the quality of the analyses carried out.
