In addition to EN this document specifies the delivery requirements for surface condition of sections to which the European Standards mentioned in Clause 2 apply and applies to all surfaces excluding edges. The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
For undated references, the latest edition of the referenced document including any amendments applies. EN , Delivery requirements for surface condition of hot-rolled steel plates, wide flats and sections Part 1: General requirements.
For the purposes of this document, the following terms and definitions apply. The surface requirements and repair conditions are subdivided into 2 classes and each class is further subdivided into 3 subclasses: Class C General applications. The surface condition shall comply with the requirements of 6.
Class D Special applications. Subclass 2 Repair by welding is only permitted if agreed at the time of the order and under agreed conditions see 6. Subclass 3 Repair by welding is not allowed. 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 the order. Discontinuities not exceeding the limits of Table 1 are regarded as being inherent of the manufacturing process and are permissible irrespective of their number.
Defects Discontinuities with a depth exceeding the limits of Table 1 shall be repaired irrespective of their. Table 1 Maximum permissible depth of discontinuities for class C Dimensions in millimetres Nominal thickness of the product t Maximum permissible depth of discontinuities.
Discontinuities not exceeding the limits of Table 2 are regarded as being inherent of the manufacturing process and are permissible irrespective of their number. Table 2 Maximum permissible depth of discontinuities for class D Dimensions in millimetres Nominal thickness of the product t Maximum permissible depth of discontinuities. Defects Discontinuities with a depth exceeding the limits of Table 2 shall be repaired irrespective of their.
The maximum permitted grinding allowance below the minimum thickness as specified in the European Standards specifying tolerances is given in Table 3. Futhermore the following conditions apply. Table 3 Grinding allowance below the minimum thickness Dimensions in millimetres Nominal thickness of the product t Maximum permitted grinding allowance below the minimum specified thickness.
The following conditions apply for the repair by welding of defects which cannot be repaired by grinding as stated under 6. Repair by welding is only allowed if agreed at the time of the order. In this case requirements different from 6. EN , Hot rolled taper flange I sections - Tolerances on shape and dimensions. EN , Hot-rolled steel equal flange tees with radiused root and toes - Dimensions and tolerances on shape and dimensions.
EN , Structural steel equal and unequal leg angles - Part 1: EN , Structural steel equal and unequal leg angles - Part 2: Tolerances on shape and dimensions.
