NFPA/T3.5.26 R2-2000 (R2009)
Hydraulic valve - 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 hydraulic valve (Revision of NFPA/T3.5.26 R1-1996)
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 valves; common requirements and an industry-wide philosophy in judging one type of pressure capability for hydraulic valves typically used in fluid power applications; uniform methods of product comparison; hydraulic valves may contain one or more pressure zones.
