NFPA (Fluid) T3.12.10 R2-2000 (R2019)

Air line filter, regulator and/or lubricator - Pressure rating supplement to NFPA/T2.6.1 R2-2000, Fluid power components - Method for verifying the fatigue and establishing the burst pressure ratings of the pressure containing envelope of a metal fluid po



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.
