28、erties of the railcar bodyshell and other major structural components. The requirements on welded joints specified in this European Standard are not applicable to welded assemblies and sub-assemblies as they are specified for material qualification purposes only. It specifies particular requirements
29、 regarding qualification, quality control, material properties and dimensional tolerances. Furthermore, guide-lines for application and use are given. 2 Normative references The following referenced documents are indispensable for the application of this document.

Prod
36、ucts included in one inspection lot shall be manufactured in the same production unit 3.3 heat treatment batch or lot quantity of products of the same grade or alloy, form, thickness or cross-section and produced in the same way, heat-treated in one furnace load, or such products solution-treated an
37、d subsequently precipitation-treated in one furnace load. More than one solution-treatment lot can be included in the precipitation furnace load 3.4 structural property property having a direct effect on the static and dynamic load carrying capability of a component or assembly 4 Ordering informatio
38、n The ordering information shall be formulated as laid down in EN 586-1. Reference to this European Standard shall be made. In addition, it shall be indicated whether the forging is intended to be welded or not. If the purchaser requires the ultrasonic inspection of the forging stock or the forgings
39、, this shall be stated in the order. 5 Requirements 5.1 Production and manufacturing processes Unless otherwise specified on the order, the production and manufacturing processes shall be left to the discretion of the manufacturer. Unless it is explicitly stated on the order, no obligation shall be
40、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. The manufacturer shall establish and maintain inspection plans d
41、efining all inspections and tests to be performed on the forging to fulfil the requirements of this European Standard and any other agreed requirement, the frequency of the tests and the type of record to be established. The inspection plan shall specify for each inspection or test whether it is to
42、be performed per cast, per forging lot, per heat treatment batch, per inspection lot or per any other lot of importance. The inspection plan shall comply as a minimum to the test procedures and test requirements stipulated in this European Standard (see Table 3). The inspection plan shall include ad
43、ditional schemes for appropriate process control. If required the inspection plan shall be submitted to the purchaser for approval before start of production. The manufacturer shall be responsible for carrying out all inspections and tests required by this European Standard, prior to the shipment of
44、 the forging. If the purchaser wishes to inspect the forging at the manufacturers works, he shall stipulate this at the time of placing the order.
