US MIL-STD-1629
US MIL-STD-1629, Procedures for Performing a Failure Mode, Effects and Criticality Analysis, is a long-recognised FMEA standard used by government, military and commercial organisations worldwide. Originally published in 1980, US MIL-STD-1629 provides procedures for identifying failure modes and effects and then extending FMEA analysis to include criticality, maintainability and vulnerability assessments. Although each of these different tasks, which are listed and described in Table 6-1, are similar to each other, they analyse different data.
Table 6-1. MIL-STD-1629 Tasks
Title
Description
Task 101: Failure Mode and Effects Analysis
A qualitative method used to study the effects of item failure on system operation and to classify each potential failure according to its severity.
Task 102: Criticality Analysis
Criticality analysis extends a FMEA to include the combined influence of the severity classification and its probability of occurrence to provide a quantitative criticality rating for the component or function.
Task 103: FMEA Maintainability Information
FMEA maintainability information supplies early criteria for maintenance planning, logistics support analysis, test planning, and inspection and checkout requirements, and identifies maintainability design features that require corrective actions.
Task 104: Damage Mode and Effects Analysis
Damage Mode and Effects Analysis (DMEA) provides early criteria for survivability and vulnerability assessments. Because DMEA is primarily applicable to weapon systems, it is not addressed in this document. For additional information on DMEAs, refer to Task 104 in MIL-STD-1629.
