For F76 BS&W testing, what is the specified RPM and duration?

Explanation:
F76 BS&W testing relies on centrifugation to separate water and sediment from the fuel, so the speed and time must produce clean separation with repeatable results. The specified procedure uses 1500 rpm, and the duration is 15 minutes plus an extra minute to ensure complete settling—effectively 16 minutes total. This exact combination is chosen to achieve reliable separation without over-emulsifying or wasting time. Other speeds or longer durations can risk incomplete separation or sample issues, so they don’t match the standard procedure.
