If, however, the presence of other elements is indicated or suspected in
12、the course of routine analysis, further analysis shall be made to determine conformance to the limits specified for other elements.AMS-QQ-A-225/5 SAE AMS-QQ-A-225/5- 3 -3.2 Mechanical Properties: 3.2.1 Mechanical Properties of Material as Supplied: The mechanical properties in the direction of worki
13、ng shall conform to the requirements of Table II for the temper specified.3.2.2 Mechanical Properties After Heat Treatment: In addition to conforming to requirements of 3.2.1, material supplied in the tempers identified in the following paragraphs shall, after having been processed to tempers also i
14、dentified therein, have properties conforming to those specified in Table II, as applicable.3.2.2.1 Material in the Annealed (O) Temper: Material supplied in the O temper, without subsequent cold work or forming operations, shall, after solution heat treatment and natural aging, develop the properti
15、es specified for the T42 temper.3.2.2.2 Material in the T4 and T451 Tempers: Material in the T4 and T451 tempers shall, without subsequent cold work or forming operations, be capable of being re-solution heat treated and naturally aged to the properties specified for the T42 tempers. Such capability

20、ng.4. QUALITY ASSURANCE PROVISIONS: See AMS-QQ-A-225 and the following:4.1 Heat Treatment; Aging Period Before Mechanical Property Testing: Specimens in the T4, T42, and T451 tempers will not be required to be tested within 4 days after completion of heat treatment. If, within this period, the manuf
21、acturer elects to test samples which fail to meet the requirements, he can discard these initial test results and test additional specimens selected after four days of aging. These specimens shall be selected from the same locations in the lot from which the prior specimens were removed.4.2 Mechanic
22、al Test After Heat Treatment: 4.2.1 Number of Tests After Heat Treatment: From material in the annealed (O) temper, an additional number of specimens equal to those required by AMS-QQ-A-225 shall be taken and tested after solution heat treatment to determine compliance with 3.2.2.5.
