New Major Version for an Essential Standard
MIL-STD-810 moved from version ‘G’ to version ‘H’
This is a crucial update to defense industry testing. Everyone involved in testing needs to be generally aware of the changes and know where to learn the details when the new version shows up in a specification
Why MIL-STD-810 is vital to the testing industry
MIL-STD-810 is the DoD standard defining environmental lab test methods, cited in in the specifications for virtually every piece of deployable military hardware. It is a comprehensive document, consisting of 1089 pages and covering the complete range of test types, from fungus to gunfire shock. Vibration Research customers are especially concerned with the detailed descriptions of approved vibration test profiles and shock testing methods. It is a public standard, available for anyone to download and reference.
Why the new version of MIL-STD-810 is so important
MIL-STD-810 has been around since 1962. There have been periodic change notices, updating the standard, but only occasionally are there major new versions, indicated by a new ‘letter’. The last version, ‘G’, was first released in 2008, with a Change version released in 2014.
Version ‘H’ emphasizes a tailored approach for environmental testing, focused on ensuring that systems will be able to withstand the harsh climatic, shock and vibration environments expected during a service lifetime. The new version also includes extensive updates and some new test descriptions.
What ‘H’ means for vibration and shock test labs
Labs need to be prepared to run the updated test profiles and use newly defined methods, because MIL-STD-810H will soon be part of the specifications coming from their customers. Among the changes are:
- Added details and descriptions of a sine burst specification used for crash hazard acceleration testing
- New diagrams for test fixture designs
- A requirement for frequency adjustment during Sine Resonance Track and Dwell (SRTD) tests to ensure maximum response, using either phase tracking or peak tracking
- Updated tolerances for all random and sinusoidal vibration tests
- New direction for material orientation during transportation vibration testing
- Dozens of new vibration test profiles, covering sine dwell, random, and sine on random test modes
- Expanded description and direction for Time Waveform Replication (TWR)
Helping our customers comply with MIL-STD-810H
Vibration Research is committed to supporting customer success. Part of that is understanding important test standards and then making it easy to drive tests that fit those standards.
We’ve already spent significant time with MIL-STD-810H, working to put the new test profiles into the current version of VibrationVIEW software. You’ll be able to find those test profiles in the screen below, with MIL-STD-810H added below MIL-STD-810G.
Customers will need VibrationVIEW2019 to access the new test profiles, so make sure to download it at your earliest convenience.
