Hi Bev,

MUST System II...gee we're still using the system I.

We typically don't use a pass/fail criteria based on the data from the
wetting balance test, unless a good portion of the data points fall below
the zero buoyancy line.

We have materials that pass the wetting balance, but we fail them based on
visual acceptance criteria, ie. dewetting and non-wetting conditions.

What I'm getting at, is we don't accept materials based on the wetting
balance test alone .

One would think that if you did a sufficient amount of components you could
get enough data to determine what an acceptable pass fail criteria would be
based on wetting forces alone.

As far as set points for F1 and F2, run a few components and see were they
fall to set up a base line.
