Military Standards Specification Testing

About MIL Standards

Military standards are the foundation of almost all quality, reliability, and testing specifications used in the electronics industry today. Knowledge and understanding of industry practices can be unattainable without a thorough comprehension of the underlying military documents (especially since some industry specs are just re-packaged military specs). However, the long delays between revisions and the increasing relevance of commercial specifications, even for high-reliability, harsh environments, can make blind allegiance to military specifications costly and potentially disastrous.

DfR has a unique capability, through our comprehensive knowledge of industry best practices and our physics-of-failure based approach to reliability assurance, to understand which test methods are most relevant to your component’s or product’s requirements.

At DfR, test methods are not called out in a blanket fashion nor applied as unalterable routines, but are selected and tailored to generate the most relevant test data possible.

For a large number of our customers, we have developed qualification plans that incorporate only the most appropriate test methods and then review and modify those test methods to provide the quality and reliability required while minimizing the time and resources expended.

DfR is experienced in providing testing and analysis as per MIL-STD-202G, MIL-STD-750E, MIL-STD-883G, and MIL-STD-810F[c2]. The first three standards are designed to provide test methods for passive, discrete, and active components, respectively. The first three standards are also managed and controlled by the Defense Supply Center, Columbus (DSCC), an activity under the Defense Logistics Agency, which is the supplier to the military for spare parts (over $2 billion in annual sales). The fourth standard, MIL-STD-810F, provides test methods for sub-system (circuit card assemblies) and system level, and is controlled and managed by the U.S. Army Developmental Test Command.

As a quick aside, notice anything missing? That’s right: Printed Circuit Boards. The military standard for PCBs was canceled in 1984 and nothing has replaced it. Don’t worry; DfR can help you here too.
