VW 80300 is a companion document to the manufacturer's better known electrical component standard, and the relationship between the two illustrates how a large manufacturer organises a test programme across many suppliers and many categories of component. One document states general requirements that apply to a class of components and the conditions under which they are assessed; the companion document sets out the test requirements for particular categories or particular aspects, so that a programme cites both and the supplier assembles the applicable combination. A supplier meeting the pair for the first time should establish which document governs which aspect before writing a test plan, since the same phenomenon may appear in both with the level stated in one and the measurement conditions in the other. The arrangement has a practical benefit for the supplier, since it means that a test programme can be drawn up from the pair of documents without needing separate instructions for each category of test.
