MIL-S-901

Military Specification MIL-S-901D[1] is for high-impact mechanical shock which applies to equipment mounted on ships.

The MIL-S-901D specification covers shock testing requirements for ship board machinery, equipment, systems, and structures, excluding submarine pressure hull penetrations.

The purpose of these requirements is to verify the ability of shipboard installations to withstand shock loadings which may be incurred during wartime service due to the effects of nuclear or conventional weapons.

For the standard floating platform, 60 pounds (27 kg) of HBX-1 explosive is placed 24 feet (7.3 m) underwater at various distances from the barge and detonated.

[citation needed] Military standard MIL-DTL-17060G(SH),[3] confirms two types of electric motors, Service C and Service A. High-impact shock test for electric motors is defined into weight categories.
