This allows the salvage of components with damaged threads, out of position holes, etc. 4 Quality assurance 4.1 Qualification 4.1.1 Purpose The purpose of qualification tests is to ensure that the insert design and insert manufacturing conditions allow the insert to comply with the requirements of this standard. 4.1.2 EN 9133 Qualification inspections and tests (requirements, methods, numbers of thin wall salvage inserts) are specified in Table 1. They shall be carried out on: each type and diameter of thin wall insert, 25 thin wall inserts selected from a single inspection lot by simple random sampling. The test programme may possibly be reduced, or the qualification of the thin wall insert be granted without inspection
