Military Standard 810 Testing

This four-day class focuses on the purpose of each test, the equipment required to perform each test, and the methodology to correctly apply the specified test environments. This class is applicable to ANY testing done to Environmental test standards including DO-160, IEC specifications, and all other documents which provide test methodology for environmental testing. The test methods explained and taught in this class apply to environmental testing of ANY equipment whether it is intended for military/aerospace, commercial, or consumer use. Vibration and Shock methods are covered together. We overview Sine and Random Vibration, also classical waveform shock testing, drop testing and Shock Response Spectrum Testing. We include instrumentation, vibration equipment, control systems and fixture design. We discuss each climatic test individually, focusing on requirements, origination, equipment required, test methodology and understanding of results. Class members will tour a lab (in person or virtually) that daily performs the full spectrum of 810H tests. The lab visit will include a demonstration of the vibration test equipment and test techniques discussed in class. An instrumented resonant structure is excited first with slowly sweeping constant acceleration sine vibration. As the frequency increases the observers will see directly the decrease in displacement. The sine vibration demonstration will be followed by an all-frequencies-simultaneous random vibration. Responses are compared. All class times above are local time. 500.6 Low Pressure (Altitude) 501.7 High Temperature 502.7 Low Temperature 503.7 Temperature Shock 504.3 Contamination by Fluids 505.7 Solar Radiation (Sunshine) 506.6 Rain 507.6 Humidity 508.8 Fungus 509.7 Salt Fog 510.7 Sand and Dust 511.7 Explosive Atmosphere 512.6 Immersion 513.8 Acceleration 514.8 Vibration 515.8 Acoustic Noise 516.8 Shock 517.3 Pyroshock 518.2 Acidic Atmosphere 519.8 Gunfire Shock 520.5 Combined Environments 521.4 Icing/Freezing Rain 522.4 Ballistic Shock 523.4 Vibro-Acoustic/Temperature 524.1 Freeze / Thaw 525.2 Time Waveform Replication 526.2 Rail Impact 527.2 Multi-Exciter 528.1 Mechanical Vibrations of Shipboard Equipment (Type I – Environmental and Type II – Internally Excited) Classroom discussion is supported by projected visuals and video clips. Commencing with a review of basic vibrations, we will explore vibration measurements and analysis. We’ll compare sinusoidal vs. random vibration testing systems, specifications, standards and procedures. We will emphasize vibration and shock test fixture design, fabrication, experimental evaluation and usage. We will study shock measurement, shock response spectrum (SRS) and shock testing. Climatic testing will be looked at in great detail, emphasizing required equipment and instrumentation, correct interpretation of specifications and hints to ensure that the tests are brought to a successful conclusion. In addition to the detailed observations of chambers in the Lab, numerous photographs of general purpose and special purpose chambers are provided such as Solar Radiation and Rain. Along with “catalog photos” of chambers, the instructor shows unpublished factory in-construction via photos of chambers. The course emphasizes topics you will use immediately. Suppliers to the military services protectively install commercial-off-the-shelf (COTS) equipment in our flight and land vehicles and in shipboard locations where vibration and shock can be severe. We laboratory test the protected equipment to (1) assure maximum equipment survival and possible combat and (2) meet commercial test standards, IEC documents, military standards such as STANAG or MIL-STD-810H, DO-160, etc. Few if any engineering schools teach about such protection or such testing. Hence this specialized course. Comparison of 810 Revisions. 810H is the latest revision. MIL-STD-810 has been revised roughly every 8 years since it was introduced in 1962. Some of the earlier revisions are occasionally cited in procurement contracts. This course covers ALL the test methods of the latest revision. The last method numbers are found in the final column of this available-for-download PDF file. The instructor will also discusses commonly specified older legacy methods. Each participant also receives a copy of Wayne Tustin’s text A minimal-mathematics Introduction to the Fundamentals of Random Vibration and Shock Testing, HALT, ESS & HASS, also Measurements, Analysis & Calibration. The text includes digital files containing a number of video clips pertaining to sine and random vibration and shock behavior and testing Introduction to Military Standard testing – Dynamics Introduction to Military Standard testing – Climatics Climatics lab demonstration Reporting on and certifying test results Course summary; optional final examination; award of certificates Text Material Instructor Steve Brenner has prepared a highly valuable 3-ring binder.
