BS EN 10360:2015 pdf download – Hot, warm or cold forging — Repair conditions prior to delivery 1 Scope This European Standard defines the forged components surface repair conditions and control to preserve their functionality. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 functionality of forging set of properties and characteristics of a workpiece/component that provides it with the capability of complying with the specified requirements 2.2 repair set of operations carried out in order to remove detected surface defects 2.3 prohibited repair area area of a workpiece/component where the repair is not permitted 2.4 surface imperfection discontinuity identified as not affecting the function of the workpiece/component, which may be left without repair [1] 2.5 surface defect discontinuity identified as affecting the workpiece/component function which shall be repaired [1] 3 Prohibited repair areas The prohibited repair areas shall be specified by the purchaser, at time of enquiry and order. Supplementary prohibited areas, which can be defined as consequence of the manufacturing process, shall be agreed between manufacturer and purchaser at time of enquiry and order. 4 Removal of surface imperfections Surface imperfections shall be removed only by request of the purchaser. In case of agreement, the removal procedure shall be the same as for surface defects. 5 Removal of surface defects 5.1 Surface defects removal method Surface defects shall be removed by grinding, scraping, polishing, chipping, machining or by any other process that preserves the workpiece/component functionality. Surface defects shall be removed by welding or powder metallurgy only with the agreement of the purchaser. The equipment used to remove the surface defects shall be suitable for the grade of the material, the location, the surface defect form and the workpiece/component geometry. The manufacturer shall develop the method to avoid masking the imperfections and increasing the repairs. If applicable, the processing should be carried out by successive passes perpendicular to surface defect direction. Following agreement between the purchaser and the manufacturer, the repaired area of the workpiece/component can be retested by the original non-destructive testing (NDT) method 5.2 Surface condition of the repaired area In the repaired area, the surface shall not be altered by an excessive temperature rise and by the presence of sharp edges, chatter marks or grooves. Pits may remain after repair; their surface should remain in the continuity of the vicinity surface of the workpiece. 5.3 Operations carried...
