for material analysis, it is valuable to know exactly how the calculated weight is calculated. In some cases we have alternative suppliers for the same supplier part with not only different material content, but also different weight. For analysis of recycling volumes, we want to have a so good value as possible. Until we can specify the percentage that is used from each supplier, we start with an average value based on the assumption that all are used equally. Do anybody know exactly how the "calculated mass" is calculated?
