Test Description
The full load will initially be applied to the sample for a one-second period, and then removed for
twenty seconds before it is again applied for the full 240 second test period. The short pre-loading
ensures that the beam is well seated on the supports before the actual test begins. Since some slight
deformation will occur, the twenty-second unloading period allows the beam to recover to the
original state.
The progress of the test can be observed by following the graph plot of load and deflection
appearing on the computer monitor. At the end of the loading period, there is an automatic return
to zero load condition and the graph plot is redrawn with revised vertical axis scale values if the BBR
Autoscaling feature is enabled. Refer to Figure 21 for an example of a test graph.
