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.
