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 task times, rates and totals are illustrative teaching values and belong to no source.

Standards and handbooks

  1. MIL-HDBK-472, Maintainability Prediction, US Department of Defense (the five procedures, and the task-by-task synthesis of corrective maintenance time that Procedure V carries in an early-design and a detailed method).
  2. MIL-HDBK-470A, Designing and Developing Maintainable Products and Systems, US Department of Defense (the design side: access, standardisation, test points and the human factors the prediction only measures).
  3. MIL-STD-471A, Maintainability Verification/Demonstration/Evaluation, US Department of Defense (the demonstration the prediction is a hypothesis for: sampling, timing and the comparison against the predicted mean and percentile).
  4. IEC 60706-2, Maintainability of equipment, Part 2: Maintainability requirements and studies during the design and development phase, International Electrotechnical Commission (the international treatment of maintainability studies through design).
  5. MIL-STD-1629A, Procedures for Performing a Failure Mode, Effects and Criticality Analysis, US Department of Defense, 24 November 1980 (Task 103, the maintainability information the worksheet already carries: how each mode is isolated and what putting it right involves).
  6. MIL-STD-2165, Testability Program for Systems and Equipment, US Department of Defense (where the isolation element of the task time is decided).

For the repair-time distribution itself and how it is measured rather than predicted, see the Maintainability concept pages; for the failure rates every weighting depends on, the Reliability Prediction references.
