8、BSI BS EN 10163-1:1991 ii BSI 04-1999 National foreword This British Standard has been prepared under the direction of the Iron and Steel Standards Policy Committee and is the English language version of EN 10163 “Delivery requirements for surface condition of hot rolled steel plates, wide flats and
9、 sections Part 1: General requirements”. Together with EN 10163-2 it supersedes BS 6512:1984, which is withdrawn. The other Parts of EN 10163 are as follows: Part 2: Plate and wide flats; Part 3: Sections. A British Standard does not purport to include all the necessary provisions of a contract. Use
10、rs of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, the EN title page, pages 2 to 10, an ins

It covers the requirements on the type,
26、the permissible depth and the permissible size of the surface area affected by: discontinuities (imperfections and defects) and repairs by grinding and/or welding. 1.2 This European Standard shall be applied so far as no other requirements for the surface condition exist in the appropriate material
27、or product standard. The requirements laid down in the appropriate material or product standard shall always prevail. 1.3 This Part 1 covers the general delivery requirements for the surface quality of hot rolled steel products such as: plates and wide flats, see Part 2; sections, see Part 3. 2 Norm

The producer can only take account of discontinuities which are
31、 visible to the naked eye. Rolling or heat-treatment scale may conceal surface discontinuities. If, during the subsequent descaling or working operations by the user, the material is found to be defective because of faulty rolling or processing by the producer, the producer shall be allowed to have
32、the product repaired provided that this is not in conflict with the appropriate material or product standard. 4 Definitions For the purposes of this European Standard the following definitions apply. 4.1 imperfections surface discontinuities other than cracks, shell and seams with a depth and/or are
33、a equal to or less than a specified limiting value imperfections may be left without repair 4.2 defects surface discontinuities including all cracks, shell and seams with a depth and/or area greater than a specified limiting value defects shall be repaired 4.3 for the most common surface discontinui
34、ties see the descriptions in Annex A. In Annex B the terms can be found in their respective languages 5 General requirements 5.1 To differentiate the surface discontinuities in terms of imperfections and defects, the depth of representative surface discontinuities shall when necessary be measured. T
35、he measurement shall be carried out from the surface of the product. The depth of the discontinuities chosen as representative ones shall be determined after the discontinuity has been removed by grinding. 5.2 Areas affected by surface discontinuities shall when necessary be determined as follows. a
36、) For isolated discontinuities (Figure 1a) the affected area is obtained by drawing a continuous line which follows the circumference of the discontinuity at a distance of 50 mm or by drawing a rectangle whose sides are 50 mm from the edges of the discontinuity. b) For discontinuities appearing in a
37、 cluster (Figure 1b), the affected area is obtained by drawing a continuous line which follows the circumference of the cluster at a distance of 50 mm or by drawing a rectangle whose sides are 50 mm from the continuous line which follows the cluster or by the product edge if this is closer. 1) Draft

39、 longitudinal direction and 20 mm in the transverse direction from the edge of the discontinuity or by the product edge if this is closer. Aligned discontinuities shall be at least 10 times their biggest width. Single or multiple appearing discontinuities whose edges are closer together than 100 mm
40、shall be considered as one discontinuity. Aligned discontinuities, whose edges in the longitudinal direction have a distance smaller than 100 mm or in the transverse direction smaller than 40 mm, shall be considered as one discontinuity.

The ground areas s
42、hall have a smooth transition to the surrounding surface of the product. In case of dispute complete elimination of the defect may be demonstrated by magnetic particle or by dye penetrant test techniques. 6.2 Welding Defects shall be completely eliminated before any weld repair is commenced. This pr
43、ocedure shall not reduce the thickness of the product to less than 80 % of its nominal thickness. Prior to weld repair of edges of flat products, the depth of the groove, measured from the edge inward, shall not exceed the nominal thickness of the product with a maximum of 30 mm.

45、ll be carried out by operators qualified in accordance with prEN 287-1. Welding procedures shall be carried out in accordance with prEN 288-1, prEN 288-2 and prEN 288-3. The weld shall be free of any lack of fusion, undercutting, cracks and other defects which could impair the workability of use of
46、the product in question as specified by the purchaser. The deposited weld material shall reach above the plate surface and shall subsequently be ground smooth and level with the product surface. After grinding smooth, ordered product thickness tolerances apply to the ground area. After repair a post
47、-weld heat treatment may be agreed between the producer and the purchaser. Proper repair shall be verified by ultrasonic, radiographic, magnetic particle or dye penetrant inspection. When the method has not been specified by the purchaser, the choice of the method is at the manufacturers options. If
48、 requested at the time of enquiry and order for every welding repair the producer shall provide reports containing a sketch, showing dimensions and location of the defect and full details of the repair procedure, including the welding consumables, eventual post-weld heat treatment and non-destructiv
49、e testing. NOTEIn certain applications, such as otherwise unwelded components of structures for which the choice of steel grade with respect to notch ductility would be determined by the presence or absence of welding or in which permissible stresses are limited by considerations of fatigue, repair by welding may not be satisfactory or may require special inspection after completion.
