21、 the delivery requirements which apply to the surface condition of hot-rolled plates and surface condition of the faces of wide flats with thicknesses of 3 mm t 400 mm.

25、 for flat products surface discontinuities with a depth and/or area greater than a specified limiting value and all cracks, shell and seams irrespective of their depth or/and area 4 General In addition to the conditions stated in EN 10163-1, it applies that if the purchaser needs to be sure that all
26、 discontinuities visible to the naked eye have been identified, assessed and where necessary repaired before delivery, products should be ordered descaled (see Clause 4 of EN 10163-1:2004). 5 Classification The surface requirements and repair conditions are subdivided into 2 classes and each class i
27、s further subdivided into 3 subclasses: Class A The surface condition shall comply with the requirements of 6.2.1 and 6.3.2.2. 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 tolera
28、nce standard. EN 10163-2:2004 (E) 5 Class B The surface condition shall comply with the requirements of 6.2.2 and 6.3.2.3. 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 tole
29、rance standard. Subclass 1 Repair by chipping and/or grinding followed by welding is permitted in compliance with 6.3.3.2. Subclass 2 Repair by welding is only permitted if agreed at the time of the order and under agreed conditions (see 6.3.3.3). Subclass 3 Repair by welding is not allowed. The req
30、uired 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 specified at the time of the order. 6 Requirements 6.1 Depth and affected area of discontinuities The requirements of

32、. A surface area with discontinuities within the limits of Table 1 but with a remaining thickness under the discontinuities less than the minimum thickness as specified in EN 10029 and EN 10051 is permissible with a maximum of 15 % of the inspected surface.

In this case is a surface area with a remaining thickness under the discontinuities less than the minimum thickness as
35、 specified in EN 10029 and EN 10051 permissible with a maximum of 2 % of the inspected surface.
