What results are you trying to document?  What is the goal of your testing?
Are you using it for process control or evaluating shops?

The test method itself is more to monitor the fabrication process.  This is
the IPC version of the ASTM comparative tracking index which someone asked
about last week.  You put a drop of water on an energized pattern and wait
for failure.  The cleaner the board, the longer the time to failure.
