  • Terrain factors
  • Biological factors
  • Environmental testing
  • Environmental conditions for materiel

Questions and answers

What must capability requirements documents and the OMS/MP identify?

Capability requirements documents and the OMS/MP will identify operating, transport, and storage quantitative testable metrics defining qualitative operational conditions.

When must simulated environmental testing be conducted?

Prior to testing in natural environments, materiel developers plan for simulated environmental testing in climatic chambers unless impractical.

Can climatic chamber tests replace natural environment tests?

Test results from climatic chambers cannot be interpreted as a total substitute for tests conducted in the natural environment because they do not provide the synergisms associated with the natural environment.

How must potentially dangerous items be designed?

Potentially dangerous items (for example, ammunition) will be designed to operate safely in all OEs worldwide plus meet ammunition specific requirements and applicable standardization agreements regardless of the likelihood that the munition will be used in any specific environment.
