4 Quality assurance
4.1 Qualification
The qualification procedure for aerospace standard products (e. g. according to EN 9133 or an
equivalent aerospace accepted and established qualification procedure) shall be used and documented
according to the specified tests if not otherwise agreed between customer and supplier.
Qualification inspections and tests (requirements, methods, numbers of bolts) are specified in Table 1.
They shall be carried out on:
 each type and diameter of bolt;
 25 bolts selected from a single batch by simple random sampling.

---------------------- Page: 8 ----------------------

SIST EN 2583:2019
EN 2583:2019 (E)
The test programme may possibly be reduced, or the qualification be granted without inspection or
testing: any such decision shall be based on the results obtained on similar types and diameters of bolts
provided that the design and manufacturing conditions are identical.
Table 2 indicates the allocation of bolt specimens for the inspections and tests.
4.2 Acceptance
4.2.1 Purpose
The purpose of acceptance inspections and tests is to check, as simply as possible, by a method
representative of actual use conditions, with the uncertainty inherent to statistical sampling, that the
bolts constituting the batch satisfy the requirements of this standard.
4.2.2 Conditions
Acceptance inspections and tests (requirements, methods, numbers of bolts) are specified in Table 1.
They shall be carried out on each batch. Bolts from the batch to be tested shall be selected by simple
random sampling.
Each nut may be submitted to several inspections or tests.
If a more stringent inspection is deemed necessary, all or part of the qualification inspections and tests
may be performed during the acceptance inspection and testing. In this case, the number of bolts
submitted to these inspections and tests is the same as that submitted for qualification inspection and
tests.
4.2.3 Responsibility
Acceptance inspections and tests shall be carried out by the manufacturer, or under his responsibility.
4.2.4 Inspection and test report
A test report showing actual numerical values shall be provided if specified in the purchase order.
