Provisions According to EN 15978, the boundary for repair should include:

  • production of the repaired part of the component and ancillary products;
  • transportation of the repaired part of the component and ancillary products, including production impacts;
  • aspects of any losses of materials during transportation;
  • the process of repairing the part of component and ancillary products;
  • waste management of the removed part of the component and of ancillary products;
  • the end-of-life stage of the removed part of the component and of ancillary products.

Water and energy usage related to the repair process should always be included. However, repair is considered optional. Please refer to the aspects ‘Repair with complete LCA’, ‘Repair with simplified LCA’ and ‘Repair with screening LCA’ for further detail.
