Note: The calculation of standard deviation is based on the distribution of individual fracture strength values being
normal, that is forming a normal curve when plotted as a frequency chart. If adhesion values for pulls that are not
completed are included in the calculation, i.e. pulled to a limit value or maximum and not to fracture, the
distribution will not be normal and the standard deviation calculation will not be mathematically correct. For the
purpose of assessing the distribution of values in this case, however, the calculation will be included as though all
the dollies were pulled to coating failure and it should be noted that the resulting calculation is for guidance only .
10.2 BATCH READINGS (Batch/Review Batch/Readings)
Displays all measurement data for each individual reading within the batch including:
Ÿ
The reading value;
Ÿ
Date and time stamp for each test;
Ÿ
Test duration.
Note: The test duration includes the hold time but does not include the time it takes for the gauge to re-wind to ‘zero’.
