SPECIFICATION OF THE TEST APPARATUS
General
The apparatus to be employed shall be the Abel Petroleum
Testing Apparatus or the Abel apparatus modified by
having an oil cup provided with a stirrer. It shall be
constructed to the dimensions herein specified within the limits
of accuracy prescribed by the tolerances set forth below.
The Oil Cup
The oil cup consists of a cylindrical vessel open at the top
and fitted on the outside with a flat circular flange projecting at
right angles.
Within the cup, fixed through the wall and silver soldered
or brazed in place, there is a gauge consisting of a piece of wire
bent upwards and terminating in a point.
Material. Brass or gun-metal

The Cover
The cup is provided with a close-fitting cover with a
downward projecting rim barely reaching the flange on the cup.
The downward projecting rim is made solid with the top or
silver soldered or brazed in place. Upon the cover are mounted
a thermometer socket, trunnions to support an oil-test lamp, a
pair of guides in which a slide moves, and a white bead. The
top of the cover is pierced by three rectangular holes
symmetrically placed on a diameter, one in the centre and the
other two as close as practicable to the inner sides of the cover-
rim and opposite each other. These three holes are covered or
uncovered by means of a slide moving in suitably disposed
guides. The slide has two perforations, one corresponding in all
particulars to the centre hole in the cover and the other to one of
the holes at the side. The movement of the slide is restricted by
suitable stops, and its length and the disposition of the holes are
such that, at the outer extremity of the movement of the slide,
the holes in the cover are simultaneously just completely
opened and at the inner extremity of the movement of the slide
they are completely closed.
The trunnions supporting the test-lamp are fixed on the
top of the grades and the lamp is mounted in the trunnions so
that it is free to oscillate. The lamp is provided with a jet to
contain a wick and is so arranged that when the slide is moved
LAWS OF GUYANA
20 Cap. 92:01 Petroleum
L.R.O. 1/2012
so as to uncover the holes, the oscillating lamp is caught by a
pin fixed in the slide and tilted over the central hole in such a
way that the lower edge of the cover bisects the circle formed
by the bore of the jet when in the lowest position. The flame
then occupies a central position within the hole in both
directions.
A suitably mounted gasket may be substituted for the
lamp.
The thermometer socket is in the form of a split tube,
mounted on a diameter at right angles to the diameter through
the centres of the holes, and fitted at such an angle as to
bring the bulb of the thermometer, when in place, vertically
below the centre of the cover and at the correct distance from it.
A white bead, the dimensions of which represent the size
of test flame to be used, is mounted in a visible position on the
cover.
Material. All parts excepting bead, brass or gun-metal.
Bead, ivory or other suitable material.

LAWS OF GUYANA
Petroleum Cap. 92:01 21
L.R.O. 1/2012
Cover Fitted with Stirrer
Provision may be made in the cover for the reception of a stirrer
which projects into the oil cup, for use with viscous materials
only.
A bush is mounted on the cover in a position
diametrically opposite the thermometer mounting and its length
is such and it is set at such an angle that the stirrer rod clears the
oil-level gauge and the blades operate below the level of and
without fouling the thermometer bulb. The bush is placed as near
as practicable to the outer edge of the cover.

Heating Vessel
The heating vessel or bath consists of two flat-bottomed
cylindrical copper vessels placed coaxially one inside the other
and soldered at their tops to a flat copper ring, greater in outside
diameter than the larger vessel and of smaller inside diameter
than the smaller vessel. The space between the two vessels is thus
totally enclosed and is used as a water jacket.
An ebonite or fibre ring of right-angle section is fitted into
the hole in the centre of the flat ring forming the top of the bath
and, when the apparatus is in use, the oil cup fits into, and its
flange rests upon, this ebonite or fibre ring so that the oil cup is
centrally disposed within the heating vessel. The ebonite or fibre
ring is secured in place by means of six small screws having their
heads sunk below the surface of the ring, to avoid metallic contact
between the bath and the oil cup.
A split socket, similar to that on the cover of the oil cup, but
set vertically, allows a thermometer to be inserted into the water-

of the test shall be 130° Fahrenheit and no heat shall be applied to
the water-bath during the test. When a test has been completed
and it is desired to make another test the water bath shall be
again raised to 130°F, which may conveniently be done while
the petroleum cup is being emptied, cooled and refilled with a
fresh sample to be tested. The next test is then proceeded with.
3. If an oil test-lamp is being used it shall be prepared
by fitting it with a piece of flat plaited candle-wick, and filling it
with colza or rape- oil up to the lower edge of the opening of the
spout or wick tube. The lamp shall be trimmed so that when
size of flame, which is represented by the projecting white bead
on the cover of the oil-cup is readily maintained by simple
manipulation from time to time with a small wire trimmer. A gas
test flame may be employed and, if so, the size of the jet of flame
shall be adjusted to the size laid down above.
4. The bath having been raised to the proper
temperature, the cup shall be placed on a level surface in a good
light, and the oil to be tested shall be poured into it, until the level
of the liquid just reaches the point of the gauge which is fixed in
the cup. Before a test is begun the temperature of the oil shall be
determined and shall be brought to approximately 60°F. The
cover, with the side closed, shall then be put on to the cup and
pressed down so that its edge rests on the rim of the cup, and the
cup shall be so placed into the bath or heating vessel, every care
being taken to avoid wetting the sides of the cup with the oil. The
thermometer in the lid of the cup has been adjusted so as to have
the correct immersion when the brass collar of the thermometer is
properly seated, and its position shall not in any circumstances be
altered. When the cup has been placed in the proper position,
the scale of the thermometer faces the operator.
5. The test-lamp shall then be placed in position upon the
lid of the cup. When the temperature has reached 66°F. the
operation of testing shall be begun, the test flame being applied
once for every rise of one degree, in the following manner—
lighted it gives a flame of about 0.15 of an inch diameter, and this

Openings A, B and C need not conform exactly to the
shape of geometrical figures bounded by arcs of two concentric
circles and intersected lengths of radii. Their boundaries must,
however, fall on or between the lines indicated by the limiting
values of the dimensional specification of the preceding test and
of the sketch.
Opening D is for a thermometer collar. Its centre is
approximately 0.75 in. (1.9 cm.) from the centre of the lid and on
a radius at an angle of not less than 50° nor more than 60° from a
radius passing through the centre of opening C. The
thermometer collar shall have an inside diameter of
approximately 0.5 in. (1.27 cm.). It shall be set at an angle of not
less than 10° nor more than 15° from the perpendicular.
Shutter.—The lid shall be equipped with a brass shutter,
approximately 0.1 in. (0.25 cm.) thick operating on the plane of
the upper surface of the lid. The shutter shall be so shaped and
mounted that it rotates on the axis of the horizontal centre of the
lid between two stops so placed that when in one extreme
position the openings A, B and C of the lid are completely closed
and when in the other extreme position these orifices are
completely opened.
Flame-exposure Device.—The flame-exposure device shall
have a tip with an opening 0.027 in. (0.7 mm.) to 0.03 in. (0.08
mm.) in diameter. The flame-exposure device shall be
equipped with an operating mechanism which, when the
shutter is in the “open” position, depresses the tip so that the
LAWS OF GUYANA
Petroleum Cap. 92:01 33
L.R.O. 1/2012
centre of the orifice is between the planes of the under and upper
surfaces of the lid proper at a point on a radius passing through
the centre of the larger opening A and approximately 0.1 in.
(0.254 cm.) from the outer edge of the opening.
NOTE.—A pilot flame for automatic relighting of the
exposure flame should be provided.
A bead 016 in. (0 4 cm.) in diameter, of some suitable
material, may be mounted on the lid so that the size of the test
flame can be regulated by comparison.
The mechanism operating the shutter should be of the
spring type and constructed so that when at rest the shutter
shall exactly close the three openings. When operated to the
other extreme the three openings in the lid shall be exactly
open and the tip of the exposure tube shall be fully depressed.
Stove.—Heat shall be supplied to the cup by means of a
properly designed stove which is equivalent to an air bath. This
stove shall consist of (1) an air bath and (2) a top plate on which
the flange of the cup rests.
Air-bath.—The air-bath shall have a cylindrical interior
1.625 in. (4.13 cm.) to 1.66 in. (4.2 cm.) deep and a diameter not
less than 0 125 in. (0.32 cm.) nor more than 0.156 in. (0.4 cm.)
greater than the outside diameter of the cup. The air bath may be
either a flame heated metal casting or an electric resistance
element.
NOTE.—If the heating element is a flame-heated
metal casting it shall be so designed and used that the
temperature of bottom and walls is approximately the same.
On this account it should be not less than 0.25 in. (0.635
cm.) thick. The casting shall be designed so that products of
combustion of the flame cannot pass up and in contact with the
cup.
If the air bath is of the electric resistance type it shall be
LAWS OF GUYANA
34 Cap. 92:01 Petroleum
L.R.O. 1/2012
constructed so that all parts of the interior surface are
heated equally. This necessitates an even distribution of
resistance wire over bottom and walls and a method of
construction such that heat is given out from the whole core of
the resistance element rather than directly from the wire.
Top plate.—The top plate shall be of metal. The total
distance from the upper surface of the plate to the bottom of the
air bath shall exceed the distance from the under surface of the
flange to the bottom of the cup by not less than 0.063 in. (0.160
cm.) nor more than 0.125 in. (0.32 cm.).
The top plate shall be mounted with an air gap between it
and the air bath. The top plate may be attached to the air bath by
means of three screws and spacing bushings. The spacing
bushings should be of proper thickness to define the air gap
which shall be not less than 0.125 in. (0.32 cm.) nor more than
0.187 in. (0.475 cm.). The spacing bushings shall be not more
than 0.375 in. (0.95 cm.) in diameter.
Thermometers.—Two standard thermometers shall be
used with the I.P.T. Standard Pensky-Martens tester. The low
range “P.M.” thermometer shall be used for tests when the
indicated reading falls within the limits 20 to 200°F. The “P.M.
high” thermometer shall be used for tests when the indicated
reading falls within the limits 230 to 100°F. For the range
200 to 230°F. either thermometer may be employed,
depending on the convenience of the operator. The
thermometers shall comply with the specifications given in Table
I.
Thermometers shall be mounted securely in the
thermometer collar so that from the top of this collar to the
bottom of the bulb the distance is 2 2 in. (+ 0 05 in.) and so that
the bottom of the bulb is 1 5 in. (+ 0-1 in.) below the level of the
rim of the cup (which corresponds to the level of the lower
surface of the portion of the lid inside the rim).

shall be taken to avoid the presence of
any gasoline or naphtha used to clean
the apparatus after a previous test.
(b) The cup shall be filled with the oil to
be tested up to the level indicated by
the filling mark.
(c) The lid shall be placed on the cup and
the latter set in the stove. Care should
be taken to have the locating devices
properly engaged. The thermometer
shall be inserted. If it is known that
the oil will flash above 220°F. the
"P.M. high" thermometer may be
selected; otherwise, it is preferable to
start with the "Low Range P.M."
thermometer and change in case a
temperature of 220 to 230°F. is
reached.
(d) The test flame shall be lighted and
adjusted so that it is of the size of a
bead A in. (4 mm.) in diameter.
(e) Heat shall be supplied at such a rate
that the temperature read on the
thermometer increases not less than 9
nor more than 11 degrees per minute.
The stirrer shall be turned at a rate of
LAWS OF GUYANA
Petroleum Cap. 92:01 37
L.R.O. 1/2012
from 1 to 2 revolutions per second.
(f) Application of the test flame shall be
made at each temperature reading
which is a multiple of 2°F. up to
220°F. For the temperature range
above 220°F., application shall be
made at each temperature reading
which is a multiple of 5°F. The first
application of the test flame shall be
made at a temperature at least 30°F.
below the actual flash point.
Application of the test flame shall be
made by operating the device
controlling the shutter and test-flame
burner so that the flame is lowered in
one-half second, left in its lowered
position for one second, and quickly
raised to its high position. Stirring
shall be discontinued during the
application of the test flame.
The flash point is taken as the temperature read on the
thermometer at the time of the flame application that causes a
distinct flash in the interior of the cup. The true flash must not
be confused with the bluish halo that sometimes surrounds the
test flame for the applications preceding the one that causes the
actual flash.
