4.2 Classification of Tests:
All technical requirements are acceptance tests and shall be performed on each powder blend or lot as applicable.
4.3 Sampling and Testing:
Shall be in accordance with the following; a lot shall be all extrusions fabricated from the same powder blend and each combination of extrusion session, reduction ratio, and annealing heat treatment.
4.3.1 Composition: One or more samples from each powder blend. Chemical analysis shall be performed on a powder blend of representative powder sample(s) obtained in accordance with MPIF 01 or other procedure acceptable to purchaser.
4.3.2 Tensile Properties: One or more round tensile specimens from each lot at any location.
4.3.3 Density: One specimen from each tot.
4.3.4 Tolerances: Each extrusion (See 8.2), unless a sampling plan has been agreed upon by purchaser and supplier.

4.4 Reports:
The supplier of the product shall furnish with each shipment a report showing the results of tests Icr chemical composition of each powder blend and for tensile properties and density of each lot. This report shall include the purchase order number, powder blend number, AMS 791 2A, serial numbers. and quantity.
4.5 Resampling and Retesting:
If a valid test on any specimen used in the above tests fails to meet specified requirements, disposition of the product may be based on the results of testing two additional specimens for each original nonconforming specimen. except as permitted by 4.5.1. Failure of any retest specimen to meet specified requirements shall be cause for rejection of the product represented. Results of all tests shall be reported.
4.5.1 Resubmittal of Rejected Lots: Lots rejected for failure to meet technical requirements may be submitted for retesting provided the producer has reworked the lots, as necessary, to correct the deficiencies or when 100% inspection confirms removal of nonconforming details.
