PD ISO/TR 10771-2:2008 Hydraulic fluid power. Fatigue pressure testing of metal pressure-containing envelopes. Rating method

In hydraulic fluid power systems, power is transmitted and controlled under pressure within a closed circuit. It is important for the manufacturer and user of hydraulic components to have information on their global reliability because of the importance of the fatigue failure mode and the relationship with their functional safety and service life. This part of PD ISO/TR 10771-2 provides a method for fatigue-testing in order to verify the rating of a pressure-containing envelope.

PD ISO/TR 10771-2 specifies testing under steady internal cyclic pressure loads in accordance with ISO 10771-1.

This part of ISO 10771 is only applicable to components whose failure mode is the fatigue of any element in the pressure-containing envelope, and that:

  • Are manufactured from metals
  • Are operated at temperatures that exclude creep and low-temperature embrittlement
  • Are only subjected to pressure-induced stresses
  • Are not subjected to loss of strength due to corrosion or other chemical action
  • Can include gaskets, seals and other non-metallic components; however, these are not considered part of the pressure-containing envelope being tested
