Tensile tests shall be conducted to determine conformance with Table 2. Sampling and test frequency are dependent upon the type and origin of specimen specified by purchaser (see 3.4.4 and 3.6) or selected by producer (See 4.3.3.4). When 3.4.2.1 applies, test frequency shall be acceptable to purchaser.
For separately-cast specimens in the homogenized, overaged, solution heat treated, and maraged condition of 3.5.2, one specimen from each master heat shall be tested for conformance to 3.6.1.
For integrally-cast specimens in the homogenized, overaged, solution heat treated, and maraged condition of 3.5.2，two specimens from each lot (see 8.3.10) shall be randomly selected and tested for conformance to properties specified by purchaser (see 3.6 and 8.5).
For specimens machined-from-casting, one casting shall be randomly selected from each lot and tested in the homogenized, overaged, solution heat treated, and maraged condition of 3.5.2 at locations shown on the engineering drawing for conformance to the properties specified by purchaser (see 3.6 and 8.5).
When size and location of specimens are not shown, two test specimens shall be tested, one from the thickest section and one from the thinnest section. Once established under 4. 4.2.2, test locations may be changed only as agreed upon by purchaser and producer.
When acceptable to purchaser, specimens machined-from-casting may be used in lieu of both separately-cast and integrally-cast specimens, and integrally-cast specimens may be used in lieu of separately-cast specimens. In each case, the resultant properties must conform to the requirements of 3.6 for separately-cast specimen requirements or to alternative requirements specified by purchaser (see 8.5).
Sample casting(s) from new or reworked master patterns produced under the casting procedure of 4.4.2 shall be approved by purchaser before castings for production use are supplied, unless such approval is waived by purchaser.
For each casting part number, producer shall establish parameters for process control factors that will consistently produce castings and test specimens meeting the requirements of the casting drawing and this specification. These parameters shall constitute the approved casting procedure and shall be used for production of subsequent castings and test specimens. If necessary to make any change to these parameters, producer shall submit a statement of the proposed changes for purchaser reapproval. When requested, producer shall also submit test specimens, sample castings, or both to purchaser for reapproval.SAE AMS 5337E pdf free download.
