8、10163-3:1991 ii BSI 02-1999 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 sections
9、Part 3: Sections”. No British Standard is superseded by this standard but reference to the surface condition of sections in BS 4360, BS 1502 and BS 7191 have been deleted by amendment. The other Parts of EN 10163 are as follows: Part 1: General requirements; Part 2: Plate and wide flats. A British S

27、 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 C and subclass 1 unless otherwise specified at the time of enquiry and order. 4
28、 Requirements 4.1 General Sections 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 C 4.2.1 Imperfections Discontinuities not exceeding the limits of Table 1 are regarded as being inherent of the m
29、anufacturing process and are permissible irrespective of their number. A surface area with a remaining thickness under the discontinuities less than the minimum thickness as specified in the applicable EURONORMS (see clause 2) is permissible with a maximum of 15 % of the inspected surface. 4.2.2 Def

Table 1 Maximum permissible depth of discontinuities for class C 4.3 Class D 4.3.1 Imperfections Discontinuities not exceeding the limits of Table 2 are regarded as being inherent of the
31、 manufacturing process and are permissible irrespective of their number. 1) Until these EURONORMS are transformed into European Standards, they can either be implemented or reference made to the corresponding national standards, the list of which is given in annex C to Part 1 of this European Standa
32、rd. 2) These EURONORMS are being transformed into European Standards. Class CGeneral applications. The surface condition shall comply with the requirements of 4.2 and clause 5. Class DSpecial applications. The surface condition shall comply with the requirements of 4.3 and clause 5. Subclass 1 Repai

Furthermore the following conditions apply: For ground areas with a thickness under the minimum permissible thickness, as specified in the European Standards or EURONORMS specifying tolerances, the sum of all ground areas shall not exceed 15 % of the surface for class C and
38、 2 % for class D. Table 3 Maximum permissible values below the minimum thickness 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 Class C subclass 1 The sum of the welded areas shall not exceed 15 % of the
39、 surface area under inspection. 5.2.2 Class D subclass 1 The sum of the welded areas shall not exceed 2 % of the surface area under inspection. 5.2.3 Subclass 2 Repair by welding is only allowed if agreed at the time of enquiry and order. In this case requirements different from 5.2.1 and 5.2.2 can
