Hydraulic fluid power — Methods to assess the reliability of hydraulic components — Part 1: General procedures and calculation method

Transmissions hydrauliques — Méthodes d'évaluation de la fiabilité des composants hydrauliques — Partie 1: Modes opératoires généraux et méthode de calcul

Abstract / scope

ISO/TR 19972-1:2009 provides a means for determining the reliability of hydraulic fluid power components using:

  • estimates from a design analysis;
  • analysis of laboratory testing to failure or suspension;
  • analysis of field data;
  • analysis of a substantiation test.

These methods apply to the first failures without repairs, but exclude certain infant mortality failures. Specific component test procedures and exclusions are provided in subsequent parts of ISO/TR 19972. ISO/TR 19972-1:2009 also provides calculation methods, reporting descriptions and examples of reliability calculations.
