What is MIL STD Testing?

Fun Fact: MIL STD Project Number Codes

MIL-STD has many codes associated with it such as 188 (Telecommunications), 810 (Environmental Engineering), and 461 (EMC). These are derived from “Project Numbers” aka Standardization Project Numbers. The standardization project numbers consists of two parts.
• The first part is the applicable FSG (Federal Supply Group), the FSC (Federal Supply Class), or the standardization area.
• The second part is a nonsignificant four-digit number serially assigned in each FSG, FSC, or standardization area.
Closely related projects initiated in the same timeframe may be identified by a project number followed by a dash and sequentially assigned subproject numbers.

MIL-STD Overview

A military standard that specifies engineering and technological requirements for Department of Defense (DoD) projects/equipment.

Some non-DoD agencies may use US military requirements in non-military fields such as non-governmental agencies, technical assistance organisations, etc. Megalab Group provides the testing capabilities required to comply with MIL STD 810 and MIL STD 461 amongst other MIL tests.

MIL-STD-810 & Environmental Tests

MIL-STD-810 is a test standard for environmental engineering and laboratory tests. This test standard tailors the environmental impact on the design of an object and measures the limitations to the circumstances that the same materiel will face during its service life. This test method uses laboratory research methods that simulate the impact of environments on material rather than attempt to replicate the environment itself.

MIL-STD-810 was developed for use by all divisions and agencies of the United States Department of Defense, but it is often used to establish an outstanding baseline for the testing of consumer goods. Manufacturers of laptops, mobile phones, and other electronic devices often monitor their products against the specification and sell them as MIL-STD-810 compliant or “ruggedized”.

MIL-STD-810 includes the following tests:

• Acceleration (513.6)
• Acidic Atmosphere (518.1)
• Acoustic Noise (515.6)
• Dust (510.5)
• Explosive Atmosphere (511.5)
• Fluid Contamination (504.1)
• Freeze / Thaw (521.3; 524)
• Fungus (508.6)
• Gunfire Shock (519.6; 522.1)
• Humidity (507.5; 520.3)
• Immersion (512.5)
• Low Pressure aka Altitude (500.5; 520.3)
• Multi-Exciter Testing (527)
• Pyroshock (517.1)
• Rain (506.5, 521.3)
• Rail Impact (526)
• Salt Fog (509.5)
• Sand (510.5)
• Shock (516.6)
• Solar Radiation (505.5)
• Temperature (501.5; 502.5; 503.5; 520.3; 523.3)
• Time Waveform Replication (525)
• Vibration (514.6; 520.3)
• Vibro-Acoustic (523.3; 528)

MIL STD 461 & EMC Tests

MIL-STD-461 was released to specify the criteria for controlling the electromagnetic interference properties of subsystems and devices for applicable Military and Aerospace requirements. MIL-STD 461 is split into two sections: Emissions and Susceptibility. Either of the radiation reactions are either conducted or radiated.

MIL-STD-461 includes the following tests:
• Conducted Emissions: Power Leads (30 Hz to 10 MHz) and Antenna Terminal (10 kHz-40GHz)
• Conducted Susceptibility: Power Leads (30 Hz to 150 kHz); Antenna Port – Intermodulation (15 kHz to 10 GHz); Antenna Port – Rejection/Undesired Signals (30 Hz to 20 GHz); Antenna Port – Cross-Modulation (30 Hz to. 20 GHz); Structure Current (60 Hz to 100 kHz); Bulk Cable Injection (10 kHz to 200 MHz); Bulk Cable Injection – Impulse Excitation; Damped Sinusoidal Transients – Cable and Power Leads (10 kHz to 100 MHz)
• Radiated Emissions: Magnetic Field (30 Hz to 100 kHz); Electric Field (10 kHz to 18 GHz); Antenna Spurious and Harmonic Outputs (10 kHz to 40 GHz)
• Radiated Susceptibility: Magnetic Field (30 Hz to 100 kHz); Electric Field (2 MHz to 40 GHz); Transient Electromagnetic Field
