TM 10-6640-238-13 1-33 ac. Oxidation Stability Bath.  The oxidation stability bath is mounted on the curbside countertop and is designed to accomplish the requirements of ASTM tests D-525 and D-873.  It operates on 110V, 60Hz, single-phase power supplied by A1CB15 located in the MAIN POWER PANEL.  It consists of an electrically heated oxidation bath with a two-bomb capacity and a three-heat switch.  It is provided with a condenser to reduce evaporation of the bath water and two stainless steel bombs for conducting tests. ad. Pensky Martens Flash Point Tester.  The Pensky Martens flash point tester is stored in laboratory cabinet A2 and is designed to comply with the requirements specified in ASTM test D-93.  It operates on 110V, 60Hz, single- phase power supplied from a convenience outlet.  It is an electrically heated closed-type unit, with two thermometers, one with a range of 20 to 2305F (-6.15C to 1105C), and the other with a range of 200 to 7005F (935C to 3715C).  The apparatus is used to determine the flash point of fuel oils. ae. Penetrometer.  The penetrometer is stored in laboratory cabinet K4 and is designed to meet the requirements of ASTM test D-217.  The penetrometer is used to measure penetration of grease with a penetration cone.  The penetrometer has a dial for measuring depth of penetration up to 38 millimeters on a single sweep of the dial needle.  The unit is supplied with stainless steel plunger bearings, preliminary setting and fine pitch micrometer adjustments, clutch, ASTM 2.5 gram needle, and a 50 gram weight. af. Pressure Recording Gauge.  The pressure recording gauge is mounted on the wall adjacent to the oxidation stability bath and is used to perform ASTM tests D-525 and D-873.  It is a two-pen-type recording gauge with clock mechanism.  It has a range of from 0 to 200 pounds (90.8 Kg/sq cm) in 8-pound divisions (.9 Kg/sq cm) recording charts and an ink set.  One complete revolution around the circular chart is equivalent to 24 hours. The recording pressure gauge is used to provide a continuous record of test results of the bombs under test in the oxidation stability bath. ag. Reid Vapor Testing Bath.  The RVP bath is mounted on the curbside countertop and is designed for ASTM tests D-323 and D-1267. It operates on 110V, 60Hz, single-phase power supplied by A1CB16 located in MAIN POWER PANEL.  It consists of the bath, a rack with a 3 bomb capacity, a 1/30-hp motor and stirrer, a thermometer, an immersion heater, 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 gauges which hang in brackets above the bomb rack. ah. Refrigerator.  The refrigerator is mounted on the curbside of the laboratory.  It operates on 110V, 60Hz, single- phase power supplied from A1CB6 located in the MAIN POWER PANEL.  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 (0. 182 cubic meters) of refrigerated storage. ai. Sampling and Gaging Kit.  The sampling and gaging kit is used to perform ASTM tests D-4057, D-287, D-1085, D-1086, D-1250, and D-1298.  It is a portable petroleum testing kit which is stored in laboratory cabinet D.  It consists of the carrying case, shoulder strap, gravity computer, cupcase thermometer, hydrometer cylinder, gasoline indicating paste, water indicating paste, image tape and bob, weighted beaker sampler, and standard hydrometers. aj. Separometer.  The separometer provides a quick, portable means for field and laboratory use to rate the ability of aviation turbine fuels to release entrained or emulsified water when passed through fiberglass coalescence material.  The test provides a measure of surface active materials in aviation turbine fuels, which are known to affect the ability of filter separators to separate free water from fuel.  The apparatus is a portable self-contained unit operating on an internal rechargeable battery.  The unit may be operated at sites where no AC power is available or it may also be operated while connected to an AC power line. ak. Tag Closed Cup Flash Point Tester.  The tag flash point tester is stored in laboratory cabinet J2 and is designed to comply with the requirements specified in ASTM test D-56.  It operates on 110V, 60 Hz, single-phase power supplied from a convenience outlet.  It is a closed type, electrically operated unit and is used to determine the flash point of mobile liquids except fuel oils, flashing below 1755F (675C).  It consists of a water bath and cover mounted on the base, overflow drain, brass test cup and standard flashing mechanism mounted on the cover. Two 20 to 2305F (6.65 to 1105C), thermometers are used with the equipment.
