Albert, we have a 600R. We normally set the time for 10 minutes as suggested
by the manual. There is an option, however, that you can save time by
running in the automatic mode where the test will terminate if the test
results remain unchanged for 4 minutes. We did use the automatic feature on
some assemblies that had a history of passing the test by a substantial
margin.
I don't remember where the 10 minute "thing" started (probably out of
MIL-P-28809) but that is what the manual recommended and that is what we
used most of the time.
IPC-TM-650 2.3.26.1 only states "for the predetermined time".
Hope that helps.

Hi TechNetters,
    I need some help regarding Cleanliness. Now I have an automatical test
machine whose name is omega 600. I usually test 10 minutes for cleanliness
of PCB. Can anyone give me the best advice about the test time of omega 600
machine which is used in PCB and tell me the cause ?
Thanks,

Best Regards,
