While the limit is fairly well documented in several standards, the test
duration is not.  Over several years of work on ionic contamination testing,
this was a major point of frustration for me.  Both the test duration and
fluid temperature should be included in the test specification.  Obviously
the results are different for a 1 minute test with room temperature fluid vs.
a 20 minute test with heated fluid.
