scope:

This standard provides:

-test and statistical methods for generating fatigue distribution data;

-test and statistical methods for conducting a verification of the pressure ratings on fluid power components;

-common requirements and an industry-wide philosophy in judging one type of pressure capability for fluid power components;

-uniform methods of product comparison.

This standard limits conditions as follows:

-constant amplitude, pressure induced loading of the elements that constitute or maintain the pressure containing envelope;

-product life of at least 100,000 cycles;

-defined conditions for pressure levels and pulse durations;

-temperatures from the charpy impact transition temperature to the threshold of creep sensitivity;

-environments which are chemically compatible with the materials of the pressure containing envelope;

-materials that are aluminum, magnesium, steel, iron, copper based alloys, cobalt, titanium, stainless steels, nickel steels and monel. Specifically excluded are creep sensitive materials such as: zinc, plastic, rubber and sealing devices.

This standard encourages manufacturers to use this common method to enhance the credibility of their pressure ratings.
