FUNCTIONAL DESCRIPTION OF LABORATORY UNIQUE EQUIPMENT -
continued.
d.
Anti-Icing Additive Test Kit. This apparatus is contained in a carrying case and is
stored in the laboratory cabinet No. 5. It consists of a hand held, direct reading refractometer,
support base rod and ring, separator funnel, graduated cylinder, aluminum dishes, piston
pipets, and a polypropylene bottle. It is used to determine the percent volume of anti-icing
additive in jet turbine engine fuels.
e.
Reid Vapor Pressure Testing Bath. The RVP bath is used for ASTM tests D-323 and D-
1267. It is mounted on the curbside countertop. It operates on 110V, 60 Hz, single-phase power.
It consists of the bath, a rack with a 3-bomb capacity, a 1/30 hp motor and stirrer, a
thermometer, an immersin heater and, a thermoregulator. It is provided with bombs for
testing that are stored in a rack on the wall adjacent to the RVP bath and pressure gages which
hang in brackets above the bomb rack.
f.
Manometer. The manometer is mounted on the laboratory roadside wall, next to the
water demineralizer. The manometer provides the primary basic standard of pressure
measurement. It is used in the laboratory to calibrate the RVP gages. It consists of a glass
column supported within a frame and connected at the bottom by a U-shaped tube to the
manometer fluid reservoir. It has a duplex-type scale calibrated in inches and tenths on the
left side of the tube, pounds and tenths using mercury on the right side. It is also equipped with
high pressure (HP) connection, low pressure (LP) connection, fill plug, drain plug, vent plug,
and a zero scale adjustment knob.
g.
Refrigerator. The refrigerator is mounted on the roadside of the laboratory. It operates
on 110V, 60 Hz, single-phase power.
It is designed and constructed for explosion-proof
operation. Components that might create sparks or arcing have been enclosed and insulated
against volatile, explosive fumes and gases that might escape from containers stored in its
interior or envelope its exterior. It provides 6.5 cubic feet (.182 cm) of refrigerated storage.
h. Copper Strip Corrosion Bath. The copper strip corrosion bath is used to perform ASTM
test D-130. It is mounted on the roadside countertop. It requires 110V, 60 Hz, single-phase
power which is provided from one of the convenience outlets in the laboratory compartment. It
is used to determine relative corrosivity caused by sulfur compounds in petroleum products.
The apparatus consists of a constant temperature bath having a temperature range from
ambient to 221°F ± 1° (105°C ± 0.5°), a 750W copper immersion heater, a thermoregulator, a
Soxhlet condenser and a constant water level device. It has a removable top plate and is
provided with a test tube rack, test bombs, a thermometer, four rubber stoppers, copper strips,
copper strip corrosion standards and has the capacity to hold four bombs.
i.
Laboratory Ovens. The laboratory oven is used for ASTM test D-2276. It operates on
110V, 60 Hz, single-phase power. It is mounted on the curbside countertop. The oven employs
gravity convection as a method of heat transfer within its chambers. It is provided with two
highly accurate hydraulic thermostats (one for control and one for high limit safety) from a
single control. This provides a sensitivity to .45°F (.25°C). The oven has a maximum operating
temperature of 437°F (225°C). It is supplied with a thermometer with a temperature range of 0
to 482°F (250°C).
