By confirmation of the use of parts, we mean an inverted parts list that gives information on what materials and raw materials were used for.
Brief description
When confirming the use of a part, the analytical use of the part in the final product is not shown, but the frequency of use of the part is collected in groups. In this way it should be clarified for which product in what quantity the considered single part will be required. Naturally, also as with parts lists, the structure of the product must be known here as well. As with parts lists, a distinction can be made between schematic evidence of use, structural evidence of use and quantitative evidence of use. Partial proofs of use are used for synthetic demand calculations.
