About MIL-DTL-901E

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

MIL-DTL-901E test methods

Mission- and safety-critical systems should be built, tested and proven to work reliably, especially in harsh or combat environments. To help ensure the survivability and reliability of shipboard systems, detailed specifications are included to limit ambiguity or uncertainty.

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

• Lightweight and medium weight shock machine tests
• Heavyweight shock test performed on a floating shock platform
• Medium weight deck simulating shock test on deck-mounted equipment or deck simulating shock machine (DSSM)

There are two shock grade categories. Grade A applies to items essential to the safety and continued combat capability of the ship. Grade B applies to items that are not essential to the safety and combat capability of the ship, but could become a hazard to personnel or the ship as a whole as a result of exposure to shock.

MIL-DTL-910E further categorizes items to be tested by type—as a principal unit, subsidiary component or subassembly—and equipment class. Tests are then classified according to the item type: Type A tests apply to a principal unit, Type B tests to a subsidiary component and Type C tests to a subassembly.

MIL-DTL-901E compliance

When evaluating solutions for mission- and safety-critical applications, look for products designed specifically to be rugged and reliable. Crystal Group products are meticulously engineered, manufactured and assembled to withstand challenging applications, harsh elements and extreme environments.

It is always advisable to confirm that a particular solution complies with MIL-DTL-901E before investing in and fielding it. Verify the test methods and test parameters used, and whether an internal or independent test facility was employed.
