The test item shall be prepared in accordance with General Requirements, S.2.
The temperature control surfaces of the test item shal1 not directly face any abnormal heat source. Any operational performance check shall be accomplished in accordance with General Require- ments, 3.2. All equipment shall be operated (excludingany propulsion svsteml and”measurements made as suecified in the vehicle or equipment _, –.-..., specification. The test chamber s~all then be reduced to t“hat“pr~ssure determined through compliance with 2.1 of this test method and the chamber walls cooled or below 100”K.
Thermal energy correspondingto the appli- cable value and manner of exposure determined through compliance with 2.2.1 of this method shall then be applied to the test item.” The normal rotational mode of the test item along with other requirements and conditions shal1 then be established and maintained throughout the test. Measurements made during the test shall be compared with the data obtained in accordance with General Requirements, 3.2. At the conclusion of the test, the test chamber shall be returned to standard ambient conditions and stabilized and the test item inspected in accordance with General Requirements, 3.2. ) 517.2-9 MSTHOO 517.2
