Overview

EN 10360:2015 - "Hot, warm or cold forging - Repair conditions prior to delivery" is a CEN European Standard that defines the conditions, methods and controls for surface repair of forged components (primarily iron and steel forgings) so that their functionality is preserved prior to delivery. It covers definitions, prohibited repair areas, permitted removal methods, surface condition requirements after repair, acceptance rules and operator training requirements.

Key topics and requirements

• Scope & definitions
  • Defines key terms such as functionality, repair, prohibited repair area, surface imperfection and surface defect.
• Prohibited repair areas
  • Areas where repair is not permitted must be specified by the purchaser at enquiry/order; additional areas resulting from manufacturing must be mutually agreed.
• Removal methods
  • Surface defects can be removed by grinding, scraping, polishing, chipping, machining or other processes that preserve functionality.
  • Welding or powder metallurgy repairs are allowed only with purchaser agreement.
• Process controls
  • Equipment and methods must suit the material grade, defect location/shape and component geometry.
  • Manufacturers must develop methods to avoid masking defects and should, where applicable, process by successive passes perpendicular to the defect direction.
  • Re-testing by the original NDT method is possible after agreement between purchaser and manufacturer.
• Surface condition after repair
  • Repaired areas must not show excessive temperature effects, sharp edges, chatter marks or grooves; small pits may remain if they follow the surrounding surface continuity.
• Post-repair operations
  • Surface-restoring operations (e.g., shot‑blasting) may be carried out to restore pre-repair properties if agreed; otherwise left to manufacturer discretion.
• Acceptance & tolerances
  • Repaired components must meet specified dimensional and surface tolerances; reference standards (e.g., EN 10243-1 / EN 10243-2) apply unless otherwise agreed.
• Operator training
  • Manufacturers must train, qualify and monitor personnel authorized to perform repairs.

Applications and who uses this standard

EN 10360:2015 is used by:

• Forging manufacturers and subcontractors who perform repairs on hot, warm or cold forgings
• Quality managers, production engineers and NDT inspectors responsible for surface repair control and acceptance
• Purchasers and procurement teams specifying repair allowances, prohibited repair areas and acceptance criteria
• OEMs and end-users in industries such as automotive, aerospace, oil & gas, and heavy machinery that rely on forged components

Practical benefits include consistent repair practices, controlled preservation of component functionality, clearer purchaser/manufacturer agreements, and traceable acceptance criteria.
