What Is MIL-STD-167-1?

MIL-STD-167-1 defines mechanical vibration testing for equipment installed on US Navy ships. It is usually paired with MIL-S-901D, which covers high-impact shock; together they qualify shipboard equipment for the naval environment.

01

The Short Answer

MIL-STD-167-1 sets vibration test requirements for equipment fitted to US Navy ships. It has two parts: Type 1, environmental vibration from sources such as wave motion and ship movement; and Type 2, the balancing of rotating machinery so equipment does not generate its own damaging vibration in service.

02

Paired With MIL-S-901D Shock

Vibration is only half of the naval environment. MIL-S-901D covers high-impact mechanical shock, the sudden loads from underwater explosions or heavy operation. MIL-STD-167-1 (vibration) and MIL-S-901D (shock) are typically specified together to qualify shipboard equipment for both sustained vibration and shock events.

  • //
    Type 1 Environmental vibration testing of shipboard equipment.
  • //
    Type 2 Balancing of internally rotating machinery to limit induced vibration.
  • //
    MIL-S-901D Complementary high-impact shock qualification.

Why It Matters

A computer destined for a marine or naval deployment is specified against these standards so it keeps running through the ship’s vibration and shock environment over a long service life.
