Mil-std-167-2a Pdf

Equipment tested for submarines (SSN/SSBN) requires a note that the vibration test is performed at ambient humidity, but the equipment must be designed for 100% condensation. The PDF does not cover this—it is in a complementary NAVSEA instruction.

The standard defines specific vibration types beyond basic environmental factors, including torsional, longitudinal, and lateral vibrations associated with propulsion systems. Acceptance Criteria: mil-std-167-2a pdf
