3.1 Pretest
The following information is required to conduct high temperature tests adequately.
- a. General. Information listed in Part One, paragraphs 5.7 and 5.9; and Annex A, Task 405 of this Standard.
- b. Specific to this Method.
- (1) Relative humidity control requirements (if necessary). (See paragraph 2.3.5 of this Method.)
- (2) Thermocouple locations. The component/assembly/structure to be used for thermal response and temperature stabilization purposes. (See Part One, paragraph 5.4.)
- (3) For Procedure III, based on the LCEP, identify the anticipated maximum non-operational temperature (exposure to high temperatures and solar loading) for the materiel, as well as the accompanying high ambient temperature. The LCEP should define whether or not the item will be operated at the maximum operational temperature immediately following the storage environment.
- c. Tailoring. Necessary variations in the basic test procedures to accommodate environments identified in the LCEP.
3.2 During Test
Collect the following information during conduct of the test:
- a. General. Information listed in Part One, paragraph 5.10; and in Annex A, Tasks 405 and 406 of this Standard.
- b. Specific to this Method.
- (1) Record of chamber temperature-versus-time data (and humidity, if controlled) for the duration of the test.
- (2) Record of the test item temperature-versus-time data for the duration of the test.
3.3 Post-Test
The following post test data shall be included in the test report.
- a. General. Information listed in Part One, paragraph 5.13; and in Annex A, Task 406 of this Standard.
- b. Specific to this Method.
- (1) Length of time required for each performance check.
- Temperature versus time data (test item and chamber).
- (2) Temperature versus time data (test item an (3) Any deviations from the original test plan.
