MIL DTL 901E High Impact Shock Test

MIL-DTL-901E is a detail (DTL) specification that defines high-impact shock testing requirements for machinery, equipment, systems, and structures on surface ships and submarines. Adopted on June 20, 2017, MIL-DTL-901E replaces MIL-S-910D as standard for verifying the ability of on-board installations to withstand environmental mechanical shocks during operation, as well as nuclear and conventional weapons.

MIL DTL 901E High Impact Shock Test

Impact (HI) shock test requirements for machinery, equipment, systems and structures on surface vessels, including tall ships and submarines, are referred to herein collectively as "ships" unless otherwise specified in this specification. The purpose of these requirements is to verify the ability of onboard installations to withstand shock loadings from the effects of nuclear or conventional weapons or from environmental mechanical shocks during operation.

MIL-DTL-901E test methods must be established, tested, and proven to reliably operate mission- and safety-critical systems, particularly harsh environments or combat environments. To help ensure the sustainability and reliability of embedded systems, detailed specifications have been added to limit uncertainty or ambiguity.

MIL-DTL-901E standard shock test methods include:

  • Light and medium shock machine tests
  • Heavy shock test performed on a floating shock platform
  • Medium weight deck simulation shock test or deck simulation shock machine (DSSM) on deck mounted equipment

There are two categories of shock degrees. Class A applies to items essential to the ship's safety and sustained combat capability. Class B applies to items that are not essential to the safety and combat capability of the ship, but which may pose a hazard to personnel or the ship as a whole as a result of exposure to shock.

MIL-DTL-901E also classifies items to be tested as main unit, auxiliary component, or subassembly by type and equipment class. The tests are then classified by item type: Type A tests are applied to a main unit, Type B tests to an auxiliary component, and Type C tests to a subassembly.

EUROLAB also provides MIL DTL 901E testing services within the scope of other equipment testing services. Thanks to these services, businesses receive more effective, high-performance and quality testing services and provide safe, fast and uninterrupted service to their customers.
