ANSI/(NFPA)T3.5.26 R2-2000 (R2005)
Hydraulic valve - Pressure rating supplement to NFPA/T2.6.1 R1-1991, Fluid power systems and products - Method for verifying the fatigue and establishing the burst pressure rating of the pressure containing envelope of a metal fluid power hydraulic valve
This standard will apply to all types of hydraulic valves typically used in fluid power applications. This standard provides: test & statistical methods for generating fatigue distribution data; test & statistical methods for conducting a verification of the pressure ratings on fluid power hydraulic valves(s); common requirements & 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 valve(s) may contain one or more pressure zones. Each pressure zone may have pressure ratings based on a maximum differential pressure to an adjacent lower pressure zone or atmosphere. Attachments can be rated as an integral part of the hydraulic valve(s) or as an independent component.
