Creating a Practice Test Procedure 156
Determine Which Processes Are Needed
A process is a “mini-program” that performs a specific test activity. You use
processes like building blocks to construct a procedure.
To complete this task, you must determine which processes on the Process
Palette are needed to accomplish the test objectives.
1. Determine which processes are needed to ramp and fatigue the physical
specimen.
This test requires three command processes:
• A Segment Command process to ramp the applied force to the mean
level from which cyclic forces are applied.
• A Cyclic Command process to apply cyclic forces to the physical
specimen to fatigue it.
• A Segment Command process to return the applied force to zero.
2. Determine which processes are needed to acquire data.
This test requires a Peak/Valley Data Acquisition process
to acquire peak/valley data as the physical specimen is being fatigued.
3. Determine which processes are needed to monitor continuity.
This test requires a Digital Input Detector process to monitor the physical
specimen continuity using a breakwire.
Note In this example the Station Manager Error detectors, rather than an MPT
process, are used to monitor structural failure of the physical specimen.
