    An example of a BOM for a mechanical assembly (in German) A bill of materials or product structure (sometimes bill of material, BOM or associated list) is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts, and the quantities of each needed to manufacture an end product.

  4. Edge crush test - Wikipedia

    en.wikipedia.org/wiki/Edge_crush_test

    Simplifications have used a formula involving the board ECT, the board thickness, and the box perimeter. Most estimations do not relate well to other box orientations, box styles, or to filled boxes. In order to calculate the value of BCT ( Box compression test ), the formula of McKee would be the easiest but also the least accurate [ opinion ] .
