Fitnessfor Purpose Assessment

(1) In the event that there is a marginal non-conformity with the quality requirements in Annex D and that correction would be:

a) detrimental to the integrity of the structure, or b) an engineering critical assessment (ECA) may be undertaken and have serious economic consequences, the following information will be needed:

a) The static and cyclic stressing requirements at the detail concerned b) The dimensions of the defect c) The material properties in the region of the defect d) Details of the environment

(2) The fatigue life can be assessed either by use of fracture mechanics (see Annex B) or by testing representative details (see Annex C).
