3 Sampling For qualification testing a quantity of at least three samples of a component (plus spares as desired) shall be taken at random from a production batch or batches, in accordance with the procedure given in IEC 60410. The components shall have been manufactured from specified materials and components in accordance with the relevant drawings and process sheets and shall have been subjected to the manufacturer’s normal inspection, quality control and production acceptance procedures. The components shall be complete in every detail and shall be accompanied by the manufacturer’s handling, mounting and connection instructions, including the maximum permissible system voltage. In the case of items, for example wires and cables, that do not have previously defined measures, a sufficient amount for the testing purposes shall be taken at random from a production batch or batches, in accordance with the procedure given in IEC 60410.
