EN 13981-3:2006 (E) 7 5 Requirements 5.1 Production and manufacturing processes Unless otherwise specified on the order, the production and manufacturing processes shall be left to the manufacturer’s discretion. Any modification of the production process qualified by the first-off procedure (see 6.1), which can affect the quality of the product shall be reported to and approved by the purchaser. In specific cases, a new first-off approval can be necessary. Unless it is explicitly stated on the order, no obligation shall be placed on the manufacturer to use the same processes for subsequent and similar orders. 5.2 Quality assurance The manufacturer shall establish and maintain a quality management system which should be at least equivalent to EN ISO 9001. Furthermore, the ordering railway company may require a formal approval of the manufacturer according to a specified procedure. The manufacturer shall establish and maintain inspection plans defining all inspections and tests to be performed on the product, the frequency of the inspections and tests and the type of record to be established. The inspection plan shall specify for each inspection or test whether it is to be performed per cast, per heat treatment batch, per inspection lot or per any other lot of importance. The inspection plan shall conform as a minimum to the test procedures and test requirements stipulated in this standard. The inspection plan shall include additional schemes for appropriate process control. If required the inspection plan shall be submitted to the purchaser for approval before the start of production.
