NFPA/T18.104.22.168 R2-2000 (R2014)Standard Title:Hydraulic filter/separator housing – 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 power hydrauReferenced Standards:NFPA/T2.6.1 R2, ANSI/(NFPA)T2.12.10, ANSI/(NFPA)/T3.10.17, ISO 1000, ISO 5598, ASTM E466Standard 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 hydraulic filter/separator housing(s); common requirements and an industry-wide philosophy in judging one type of pressure capability for fluid power hydraulic filter/separator housing(s); 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 money; specifically excluded are creep sensitive materials such as: zinc, plastic, rubber and sealing devices; to exclude the finite life RFP rating for a hydraulic filter/separator housing (such as spin-on filter) used in finite life application. See ANSI/(NFPA)T3.10.17. This standard encourages manufacturers to use this common method to enhance the credibility of their pressure ratings.
