There are numerous standards related to microelectronic device reliability. The most widely used standards are the military standards (Mil-Std) and EIA/JEDEC. Mil-Std is a collection of tests and evaluation procedures that are specially designed for reliability qualifications for military applications. EIA/JEDEC standards identify testing requirements that range from general to specific. For example, all plastic package testing must follow general guidelines specified by JESD 47, but only certain types of device packages may be required to undergo highly accelerated stress (HAST) testing. Figure 9.10 illustrates the hierarchy for EIA/JEDEC testing procedures and serves as the model for microelectronic products. The stress-test-driven qualification of integrated circuits (JEDEC Std. 47) guideline determines which tests a new design must undergo and helps product engineers identify and correct flaws that may arise. The guideline also identifies sample size requirements and testing qualifications for new devices to help expose process flaws.
Qualification Methodology for Extreme Environment Electronics
Published in John D. Cressler, H. Alan Mantooth, Extreme Environment Electronics, 2017
MIL-PRF-38535 establishes the performance requirements for the microcircuits, outlines the requirements to be met by a manufacturer to be listed and maintained on a Qualified Manufacturer Listing (QML), and provides the quality and reliability assurance requirements for all QML products to meet military, aerospace, or space performance needs. This specification and its appendices give a detailed description of the general and mandatory requirements (quality assurance, design and construction, marking, workmanship, etc.) and verification (inspection conditions, qualification procedures, quality conformance inspection, screening, quality assurance program, self-audit, etc.). In addition, space application requirements, radiation hardness assurance (RHA), statistical sampling, life test, and qualification procedures, QML certification, validation and qualification, and technology conformance inspection and screening information are also included and described in details in the specification.
EMI Measurements, Control Requirements, and Test Methods
Published in David A. Weston, Electromagnetic Compatibility, 2017
MIL-STD-461 is a document that specifies EMI requirements and test levels on military equipment, although the space industry has also widely used the specifications on nonmilitary equipment. Initially MIL-STD-461 applied to Navy, Air Force, and Army equipment. The next issue, MIL-STD-461 A, provided notices that applied to individual services. Table 9.15 provides information on which notices of MIL-STD-461 and -462 apply to either all or individual services. With the advent of MIL-STD-461E, the test requirements, test methods, and test setups contained in MIL-STD-462 have been included in MIL-STD-461E.

For safety, assessments of technological capabilities are used to determine the level of risk and processes for mitigating those risks for those who will be interacting with the system. The primary guidelines for Army safety assessments are laid out in the military standard, MIL-STD-882E. This military standard is the system safety standard practice that ‘identifies the DoD approach for identifying hazards and assessing and mitigating associated risks encountered in the development, test, production, use, and disposal of defense systems’ (MIL-STD-882E, Department of Defense Standard Practice System Safety2012, ii). These guidelines conform to the Department of Defense Instruction (DoDI) 5000.02 (DODI 5000.022017) which defines the risk acceptance authorities.2
