1.1 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 FRLs;
- common requirements and an industry-wide philosophy in judging one type of pressure capability for FRLs;
- uniform methods of product comparison.

1.2 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;
- pressure gauges are specifically excluded.

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