8、c) BSI BS EN 10163-2:1991 ii BSI 12-1998 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
9、and sections Part 2: Plates and wide flats”. Together with EN 10163-1 it supersedes BS 6512:1984, which is withdrawn. The other Parts of EN 10163 are as follows: Part 1: General requirements; Part 3: Sections. A British Standard does not purport to include all the necessary provisions of a contract.
10、 Users 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 6, an
11、inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover. Licensed Copy: sheffieldun sheffieldun, na, Thu Oct 26 03:43:30 GMT+00:00 2006, Uncontrolled Copy

Part 1 and 2 of this European Standard replaces: Part 1 and 2 of this document was originally drawn up as Euronorm 163 under the European Coal and Steel Community. With the formation of ECISS and the establishment of the ECISS work programme TC 10 was asked to pre
20、pare this document for eventual publication as a European Standard. ECISS/TC 10 met 3 and 4 May, 1990 in Brussels and agreed on the text for publication as a European Standard. The following countries were represented in that meeting: Austria, Belgium, Denmark, Finland, France, Germany, Italy, Luxem
21、bourg, Netherlands, Sweden and United Kingdom. This European Standard EN 10163-2 was approved by CEN on 1991-04-16. According to the Common CEN/CENELEC Rules, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland,

27、ts and repair conditions are subdivided into 2 classes and each class is further subdivided into 3 subclasses. The required class and subclass is specified in the appropriate material or product standard. If this is not the case the class and subclass shall be class A and subclass 1 unless otherwise
28、 specified at the time of enquiry and order. 3.2 If the purchaser needs to be sure that all discontinuities visible to the naked eye have been identified, assessed and where necessary repaired before delivery, products should be ordered descaled (see clause 3, Part 1). 4 Requirements 4.1 General Pla
29、tes and wide flats may have surface discontinuities, which may be divided into categories depending on their nature, depth and number as defined in 4.2 and 4.3. 4.2 Class A 4.2.1 imperfections 4.2.1.1 Discontinuities other than cracks, shell and seams (see 4.2.2.3) not exceeding the limits of Table
30、1 are regarded as being inherent of the manufacturing process and are permissible irrespective of their number.

31、d EURONORM 91 is permissible with a maximum of 15 % of the inspected surface. 4.2.1.2 Discontinuities other than cracks, shell and seams (see 4.2.2.3) with a depth exceeding the limits of Table 1 but not exceeding the limits of Table 2 and of which the sum of the affected areas does not exceed 5 % o
32、f the inspected surface, may be left unrepaired. 1) Until this EURONORM is transformed into an European Standard, it can either be implemented or reference made to the corresponding national standard, the list of which is given in annex C to part 1 of this European Standard. Class AThe surface condi
33、tion shall comply with the requirements of 4.2 and 5.1.1 The remaining thickness of the affected area under discontinuities and of repaired ground areas may be less than the minimum thickness as specified in the appropriate tolerance standard. Class BThe surface condition shall comply with the requi
34、rements of 4.3 and 5.1.2 The remaining thickness of the affected area under discontinuities and of repaired ground areas shall not be less than the minimum thickness as specified in the appropriate tolerance standard.

41、rinding of defects shall be carried out subject to the following conditions. 5.1.1 Class A 5.1.1.1 The maximum permissible depth of ground areas is given in Table 3. Table 3 Grinding allowances for plates and wide flats 5.1.1.2 For ground areas with a thickness under the minimum permissible thicknes
42、s, as specified in the European Standards or EURONORMS specifying tolerances, the sum of all ground areas below the minimum permissible thickness of one side of the product shall not exceed 2 % of the surface area under inspection. For products of surface area greater than 12,5 m2 the size of a sing
43、le ground area below the minimum permissible thickness shall not exceed 0,25 m2. 5.1.1.3 For the remaining thickness of two ground areas lying opposite to each other on both sides of the product the requirements of 5.1.1.1 apply. 5.1.2 Class B The remaining thickness of the repaired ground area shal
44、l not be under the minimum permissible thickness as specified in the appropriate European Standards or EURONORMS specifying tolerances. 5.2 Welding The following conditions apply for the repair by welding of defects which cannot be repaired by grinding as stated under 5.1. 5.2.1 Subclass 1 A single
45、welded area shall not exceed 0,125 m2 and the sum of the welded areas shall not exceed 0,125 m2 or 2 % of the surface area under inspection whichever is the greater. Ground and welded areas which are separated by a distance less than their average width shall be treated as a single area for the purp
