The public standards and primary documents this topic draws on.

The public standards and primary documents this topic draws on. Every factual claim in the preceding chapters traces to one of these; the worked example's matrix, rates and test set are illustrative teaching values and belong to no source.

Standards and handbooks

  1. MIL-STD-2165, Testability Program for Systems and Equipment, US Department of Defense (testability as a programme activity with its own requirements, analysis and demonstration, rather than as a by-product of design).
  2. MIL-HDBK-2165, Testability Handbook for Systems and Equipment, US Department of Defense (the guidance behind the standard: inherent testability assessment, the dependency model, and test placement).
  3. IEEE Std 1522, IEEE Trial-Use Standard for Testability and Diagnosability Characteristics and Metrics (the modern vocabulary for fault detection, fault isolation and the related figures of merit).
  4. MIL-STD-1309D, Definitions of Terms for Testing, Measurement and Diagnostics, US Department of Defense (the terms of test and diagnosis, so that a false alarm means the same thing to two organisations).
  5. MIL-STD-1629A, Procedures for Performing a Failure Mode, Effects and Criticality Analysis, US Department of Defense, 24 November 1980 (the source of the fault list and of the detection column the matrix starts from).
  6. MIL-HDBK-470A, Designing and Developing Maintainable Products and Systems, US Department of Defense (where isolation results become maintenance task times).

For the measures themselves and how they are demonstrated on hardware, see the Testability concept pages; for the mode list and the rates every figure here is weighted by, the FMECA references.
