BS EN 2583:2019 pdf free.Aerospace series – Bolts, MJ threads, in heat resisting nickel base alloy NI-PH2601 (Inconel 718) – Classification: 1 275 MPa (at ambient temperature)/ 650°C – Technical specification.
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.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.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. 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.After completion of solution, precipitation treatment and machining, the underhead radius shall be cold rolled to remove all visual signs of machining and to create cold working.BS EN 2583 pdf download.
