5. AFTER-TEST PROCEDURE - SAFETY
When the MiniMonitor is disconnected, DO NOT remove the bottom cap for
5 minutes to allow static charges to dissipate. At least one major
oil company has adopted this practice on a world-wide basis.
Accidents
are extremely rare, but we know of at least 3 fires caused by arcing
when the two halves of a monitor housing have been separated.
1.
2.
3.
4.
When the plastic monitor has been removed from the housing, place
it with the spoked or gridded side toward the tubular fitting on
the side of syringe (6).
Press it firmly in place, being certain
that the syringe handle is first pressed all the way in.
Pull outward on syringe handle one time only to extract fuel from
plastic monitor.
Remove the plastic monitor and push the handle
in
again to expel fuel into a safe container.
Additional extractions can be made if desired, but the plastic
monitor must be removed each time to expel fuel.
Replace the colored plastic plugs.
6. EVALUATION OF TEST RESULTS
The evaluation of results should be in accordance with one of the pro-
cedures in ASTM D2276/IP 216 and D3830.
1.
If the color method is to be used, open plastic monitor by inserting
and twisting a coin in the groove on the OD.
Compare the color of
the thin membrane with the ASTM color standard chart.
Report color
rating, volume throughput and state whether evaluated wet or dry.
A dry rating is preferred.
2.
If a gravimetric determination is to be made, the membrane must be
pre-weighed on a laboratory balance and then weighed again after the
test in strict accordance with ASTM procedures.
3.
If matched weight plastic monitors are used, there will be 2 membranes
of equal weight in the plastic monitor.
Pre-weighing is unnecessary.
A laboratory simply weighs both membranes after the test and reports
contamination as the difference in weight between the top and bottom
membranes.
ASTM procedures must be followed.
