24、ly. 5 Classification 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 6.2.1 and 6.3. Class D Special applications. The surface
25、 condition shall comply with the requirements of 6.2.2 and 6.3. Subclass 1 Repair by chipping and/or grinding followed by welding is permitted in compliance with 6.3.2.2 and 6.3.2.3. Subclass 2 Repair by welding is only permitted if agreed at the time of the order and under agreed conditions (see 6.
26、3.2.4). Subclass 3 Repair by welding is not allowed. EN 10163-3:2004 (E) 5 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.
