MIL-STD-2105D
4.1.3 Threat hazard assessment (THA). Develop a THA
(see paragraph 6.2) and ensure it contains an analysis of the munition life cycle. In the THA, identify potential hazards both qualitatively and quantitatively and their causes and effects. Submit the THA to the appropriate service review organization(s) for approval. A review and concurrence of
the THA is required by the appropriate service review organization(s) prior to conduct of the tests.
4.1.3.1 Environmental profile. As part of the THA, develop a life cycle environmental profile (LCEP) using the guidance available in other documents for establishing such profiles, (e.g., MIL-HDBK-1670 for air launched weapons or MIL-STD-810 for general applications). Included in the LCEP are the worst case environmental conditions and limits that munitions will encounter throughout the life cycle such as temperature, humidity, and vibration. MIL-HDBK-310 contains information to assist in developing the climatic portion of an environmental profile. Use the environmental profile in performing the THA, and cite it in the test plan.
4.2 Test parameters. Determine the safety and sensitivity characteristics of the item under conditions that simulate or duplicate the hazards of credible normal, abnormal, or combat situation(s) identified by the THA (see paragraph 6.2). Select the test parameters to reflect maximum stress levels forecasted by the THA (e.g., bullet impact velocity, maximum storage temperature).
4.2.1 Test item temperature. Unless otherwise specified (see paragraph 6.3), ensure all ambient temperature test items are at 25 ± 10 degrees Celsius (°C) (77 ± 18 degrees Fahrenheit (°F)).
4.3 Passing criteria. Passing criteria for the tests are in section. Failure to meet all predetermined test criteria is not necessarily grounds for automatic rejection of that weapon system for service use.
4.4 Hazard assessment test report. Develop a hazard assessment test report (see paragraph 6.2) that contains detailed information specified herein (see section 5) and is
consistent with the test plan (see paragraph 4.1.1). Include in
