Materials list §

You can identify the part's substances that should be tracked for regulatory compliance and reporting. Each line item consists of (a) the material, (b) the quantity and its unit of measure, (c) a calculated proportion (based on the Part mass value, supplied above), and (d) an optional location of the substance within the part. Click on a column header to sort the list.

Materials values can be changed by the part trustee (and analysts) until the part is released. After release:

The parts-per-million of the material, calculated by the system as 106 × Quantity / Part mass.
