Revision of ANSI/(NFPA)T3.21.8-1990 (R1997).

1 Scope and field of application

This standard is to be used as an alternative to ISO 12238, which is recognized as the preferred method.

This standard is intended:

--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 gases, 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.

--to establish a standard means of communicating these results.
