(9) Pensky-Martens Flashpoint Tester.
(a) Description.  The Pensky-Martens flashpoint
tester is designed and manufactured in accordance with ASTM D-93.
The apparatus consists of an electric heater with a three-heater
switch, controlling rheostat, pilot lamp, stirrer and motor, a closed
flash-cup mounted in an air bath, shutter, test flame burner, pilot
burner and thermometers.
(b) Operating Instructions. Complete instructions
for operating the Pensky-Martens flashpoint tester are described in
ASTM D-93.  No other special instructions are required.
(10) Copper Strip Corrosion Apparatus.
(a) Description.  The copper strip corrsion apparatus
(fig. 2-8) is designed to meet the requirements of ASTM D-130. The
apparatus consists of a constant temperature bath having a temper-
ature range from room-temperature to 109.4 degrees C to 110.6 degrees
C), openings for four test bombs, four rubber stoppers, a thermometer
well, copper Soxhlet condenser, thermostat and drain plug.  It is
also provided with two test bombs and an ASTM 12F thermometer having
a range of minus 5 degrees F to plus 215 degrees F (-20.6 degrees C
to 101.7 degrees C).  The overall dimensions of the apparatus is 7-
inches wide by 12-1/2 inches deep by 24 inches high (17.8 cm x 31.75
cm x 62.4 cm) and requires a minimum of 750 watts.
(b) Operating Instructions.
1.
Fill the bath with water through the bomb
hole.
2.  Connect the power cord and turn the line
switch to ON to heat the constant temperature bath to operating
temperature.
3.  Adjust the bath to the desired temperature by
turning the graduated dial on the thermostat.
4.  When the bath has reached the desired temper-
ature, remove the rubber stoppers, insert the bombs through the
openings into the rack provided and replace the rubber stoppers.
5.  Connect a cooling waterline to one of the
small tubes on the condenser and connect a drain line to the other.
This will condense the steam coming from the bath and return the
condensate to the bath.  If the water supply is insufficient to
operate the condenser, vent the steam directly into the atmosphere.
(11) Fuel Systems Icing Inhibitor Test Equipment.  If the
laboratory facility is required to determine fuel systems icing
inhibitor (FSII) in hydrocarbon fuels, the apparatus, reagents and
materials indicated in methods FTSM 5327.3 and FTSM 5340 should be
procured as applicable.  Enough glassware whould be procured to
permit six tests to be performed simultaneously.  If a sample of the
