520.5-33 information required

3.1 Pretest

The following information is required to perform a combined environments test adequately.

• a. General. Information in Part One, paragraphs 5.7, 5.9, and 5.12; and in Part One, Annex A, Task 405 of this Standard.
• b. Specific to this Method.
• (1) Purpose of the test, e.g., engineering development, flight or operation support, platform envelope verification, etc.
• (2) LCEP defining the combination of three or more of the following environments: temperature, altitude, humidity, input electrical power, and vibration to be applied simultaneously.
• (3) Test item platform envelope and/or mission profile(s).
• (4) Test item installed location within the respective platform and any specifics associated with the installed location (to include power, cooling, fixturing, etc.)
• (5) Climatic/Dynamic Sensor Locations: Mapping of control and response sensors' locations in relation to the test item and test chamber.
• (6) Data acquisition rate: The data sampling rate shall be set to accurately record all test parameter transitions. Sample rates shall be sufficient to verify parameter tolerances and change rates.
• c. Tailoring. The test profile shall be tailored to simulate the LCEP requirements to the greatest extent possible within facility limitations.

3.2 During Test

• a. General. See Part One, paragraphs 5.10 and 5.12; and information in Part One, Annex A, Tasks 405 and 406 of this Standard.
• b. Specific to this Method.
• (1) Complete record of temperature, altitude, humidity, input electrical power, and vibration levels correlated to test profile sequence. The test data sample rate shall be sufficient to demonstrate that all ramp rate requirements (Temperature, Altitude, etc.) have been met.
• (2) Complete record of materiel function correlated with test profile sequence.

3.3 Post-Test

The following post-test data shall be included in the test report to.

• a. General. Information listed in Part One, paragraph 5.13; and in Part One, Annex A, Task 406 of this Standard.
• b. Specific to this Method.
• (1) Previous test methods to which the specific test item has been subjected.
• (2) Any deviations from the original test plan.
• (3) Environmental parameter versus time data plots (temperature, altitude, humidity, input electrical power, and vibration). Sufficient detail is required to verify that all test parameters are met, including temperature and altitude ramp rates, etc.
• (4) Out of tolerance conditions, test interruptions, data gaps, etc. shall be annotated and fully described.
• (5) Document any modifications/interruptions to the test profile sequence. Refer to the paragraphs 4.4 and 5.0 for analysis of any effects due to the profile changes.
