After completing each environmental test, examine the test item in accordance with the materiel specifications. Operate the test item when appropriate for obtaining post-test data. Compare the results with the pretest data obtained in accordance with paragraph 5.9. Include the following information in the post test record and report:
- a. Test item identification (manufacturer, model/serial number, etc.).
- b. Test equipment identification, including accessories.
- c. The actual test sequence (program) used.
- d. Deviation from the planned test program (including explanation and rationale).
- e. Performance data collected on the same parameters at the same operational levels as those of the pretest (including visual examination results and photographs, if applicable).
- f. Room ambient test conditions recorded periodically during test period.
- g. Other data specified in individual methods or requirements document(s).
- h. Initial failure analyses, if applicable.
- i. A signature and date block for the test engineer/technician to certify the test data.

Interrupted Test Cycle Logic
- In-tolerance Interruption: Continue test without changing duration.
- Out-of-tolerance Undertest: Continue test and adjust time appropriately.
- Out-of-tolerance Overtest:
- If not damaged: Continue test and adjust time appropriately.
- If damaged but not repairable: Restart test at beginning with a new item.
- If damaged and repairable:
- Repairs made to critical parts: Restart test at beginning with a new or rebuilt item.
- Repairs not made to critical parts: Restart test at beginning with a new item.

Note: Regardless of the type of interruption, a safety evaluation should be conducted on the test item and facilities/test equipment prior to restart of testing.
