NFPA/T3.21.8 R1-2008 (R2013)Standard Title:Pneumatic fluid power – Measurement of response time – Directional control valvesReferenced Standards:ANSI/B93.2, ISO 1219, ISO 1000, ISO 5598, NFPA/T2.10.1M, ISO 2944.Standard Scope:To include a standardized procedure for defining, determining and reporting the response time of electrically or pneumatically operated pneumatic directional control valves. The results are applicable only to compressed air at the pressure and temperature at which the test was conducted. Although the method contained can be applied to other gasses, pressures or temperatures, these cases are outside the scope of this standard. To establish a standard definition of response time. To promote improved pneumatic fluid power systems by providing manufacturers and users with a standardized procedure for measurement of the dynamic performance of electrically or pneumatically operated pneumatic directional control valves.
