1-14. FUNCTIONAL DESCRIPTION OF PETROLEUM LABORATORY UNIQUE EQUIPMENT - continued.
Foaming Test Bath. This apparatus is designed for use in ASTM test D-892. It is stored in the laboratory
cabinets. It is a fully equipped constant temperature bath that tests foaming characteristics of lubricating oils to
determine their suitability for high speed gearing, splash lubrication, high volume pumping and other applications. It
aerates the sample through diffuser stone at 94 + 5 ml/min. and maintains sample temperature at 75 and 200 ± 1F
(24.5 and 93.5± 0.5°C ) for three-sequence testing. It uses precise solid state temperature control with a thermistor
sensor probe. A silent 1/20-hp ball bearing stirrer provides complete circulation to assure temperature uniformity.
The apparatus operates on 110V, 60Hz, single-phase power from a convenience outlet. It has a temperature range
from ambient to 275°F (134°C), controller sensitivity of ± 1°F( ± 0.5°C), and a heater range from 0 to 1500W. The
bath capacity is 9 gal. (38.51).
Tag Closed Cup Flash Point Tester. The tag flash point tester is stored in the laboratory cabinets. It operates
on 110V, 60 Hz, single-phase power supplied from a convenience outlet. The tag flash point tester is designed to
comply with the requirements specified in ASTM test D-56. It is a closed type, electrically operated unit and is used
to determine the flash point of mobile liquids except fuel oils, flashing below 175°F (67°C). 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 2300F (6.6° to 110°C), thermometers are used with the equipment.
Cleveland Flash Point Tester. The Cleveland flash point tester is stored in the laboratory cabinets. It operates
on 110V, 60Hz, single-phase power supplied by a convenience outlet. It is designed to comply with the requirements
specified in ASTM test D-92. The apparatus is an open-cup type flash point tester and is electrically heated by a
750W heater with an integral rheostat and dial control. It is used to determine the flash and fire points of petroleum
products, except fuel oils, which have an open cup flash above 175°F (79°C). The heat range is from 20 to 760F(-
6.67C to 404°C). Included with the apparatus is a permanently mounted test flame burner, pivot post thermometer
holder, and refractory top which includes a heat resistant board, cast iron plate, test flame bead, and open flash cup.
Pensky Martens Flash Point Tester. The Pensky Martens flash point tester is stored in the laboratory cabinets.
It operates on 110V, 60Hz, single-phase power supplied from a convenience outlet. It is designed to comply with the
requirements specified in ASTM test D-93. It is an electrically heated closed-type unit, with two thermometers, one
with a range of 20 to 230°F (-6.1°C to 110°C), and the other with a range of 200 to 700°F (93°C to 371°C). The
apparatus is used to determine the flash point of fuel oils.
Penetrometer. The penetrometer is stored in the laboratory cabinets. It 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.
Field pH Meter. The pH meter is stored in the laboratory cabinets. It is housed in a carrying case and is fully
portable. It operates on a rechargeable battery and is supplied with a battery charger which operates on IIOV, 60Hz,
single-phase power. The pH meter has an analog readout and is used to take pH and oxidation readings directly at
the sampling site.
