Before environmental exposure, operate the test item under standard ambient conditions (see 5.1) to ensure the test item is operating properly and to obtain baseline performance data. Include the following information in the pretest documentation:
- a. Background data of each item:
- (1) Item nomenclature, model, serial number, manufacturer, etc.
- (2) General appearance/condition.
- (3) Specific physical anomalies.
- (4) Environmental test history of the specific item.
- b. Collect pretest data on the functional parameters that will be monitored during and after each environmental test. Use functional parameters and operational limits specified in the materiel specification or requirements document. If such specifications are not provided, establish and apply appropriate parameters/limits for the pretest, the main test, and the post test.
- c. Photographs of the test item as necessary to evaluate post test results.
