In addition to the information derived from Part One, apply a brief scenario of service conditions to explain the intended simulation. Also state:
- a. The type of moisture required (vapor or spray).
- b. The initial test conditions and the temperatures to be used.
- c. Whether the test is a demonstration of survival or of functional performance.
- d. The number of cycles to be used.
3.1 Pretest
The following information is required to adequately conduct freeze/thaw tests.
- 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) Low temperature extreme and time at that temperature.
- (2) Rate of temperature rise.
- (3) Means of introducing moisture using water vapor.
- (4) Number of cycles.
- c. Tailoring. Necessary variations in the basic test procedures to accommodate LCEP requirements.
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. For test validation purposes, record deviations from planned or pre-test procedures or parameter levels, including any procedural anomalies that may occur. Include:
- (1) The transfer times between chambers (door open to door close).
- (2) Conditions at which frost forms.
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 for visual examination and performance checks.
- (2) Results of visual and operational checks (during and after testing).
- (3) Location of any free water on or in the test item.
