I.General
1.1 Characteristics
HZBS-002 is designed according to ISO13736 and IP 170 by Abel close cup method, it is suitable to
the determination of flash point of petroleum product and other flammable liquid with flash point
between -30℃and 70℃. The precision for this method is only valid for flash points in range of --5℃
and 66.5℃.It is not applicable to water-borne paints.
Main characteristics:
◆Temperature rise controlled by SSR, which can satisfy requirements of different heating rate.
◆Continuously stirring the sample and stirring is auto stopped during igniting.
◆Electrical controlled ignition.
◆Test cup lid with stirring device can be disassembled freely..
1.2 Operation condition
◆Temperature：5℃~35℃Humidity:≤85%
◆Condition：No dust, no corrosive gas and no influence of strong magnetic field.
◆Power supply：220V±22V, 50Hz, 5A grounded electrical socket
◆Gas source: Liquid petroleum gas or propane
1.3 Configuration
The instrument consists of heating unit, test device, electrical control unit, test cup and gas source.
See Figure-1.
Figure-1 Configuration

1.3.1 Test device
The test device consists of stirrer, electrical control igniting system, disassemble test cup lid and
igniter. It uses vertical model for ensuring the close seal between test cup and cover and precise
test result. During test, the stirrer, test cup lid, igniter and shutter unit are linked together, release
the lifter knob to drop the test device onto test cup to finish the operation.
Shutter unit: The motor drives the cam and driving axle to open or cover the shutter automatically.
1.3.2 Heating device
The heating voltage is adjusted by SSR, it is convenient to control the power frequency to meet
different requirements on temperature rise rate. Stirring rate can be adjusted in range of 0-40
roll/min by stirrer adjust button. Stirrer will be stop working during ignition.
1.3.3 Gas source
Beside master gas valve, we have adjusting valves for flame size adjusting for both igniting and
ever-burning flame.

II.Installation and commissioning
2.1 Unpacking and checking
2.1.1 Open the packing case and put instrument out, check if the apparent clean and without
damage, and put the instrument on test platform steadily.

3
2.1.2 Unpack the accessories carefully and inspect them according to “Accessory list”. Contact us if
any shortage or damage. Start installation if no objection.
2.2 Installation requirement
2.2.1 The instrument should be placed on steady test platform with no airflow around.
2.2.2 The distance between instrument and the walls or other shields should be not less than
200mm.
2.3 Installation and adjustment
2.3.1 Installation
Install test cup lid group onto the cup, insert the slider end into slot as below:
Insert stirrer soft rod into the stirrer as below:
Insert into this slot

4
Insert two thermometers (by client) into holder. Connect the cables for power and test device
into corresponding sockets. Connect the igniter and pilot to corresponding adjusting valves with
silicon tubes.
Rear of instrument:
Connect gas source into gas inlet and fix well.
If test in low temperature, connect intake pipe to In/Out liquid joint, connect liquid return pipe to
overflow pipe and fix well. If test not in low temperature, you can connect some PU pipe to
In/Out liquid joint and drain into sewer, open the valve then the water inside the bath can be
drained out. Connect some PU pipe to liquid return joint and also drain into sewer.
Insert into interface

2.3.2 Adjustment
2.3.2.1 Pull the screw axle by hand to observe the flexibility of the sliding unit. If any trouble, inspect
at each transmission joints for any loosing or barrier. Contact us if the trouble cannot be solved.
2.3.2.2 Move the stirrer and observe if it can touch the thermometer, if yes, adjust the position of
blade.
2.3.2.3 Gas source connection: Turn off the master gas valve and adjusting valves, connect the gas
source with the master gas valve. When igniting, turn on the master valve (Fully or half open
depending on the gas pressure), and turn left the igniting adjusting valve slowly to adjust diameter
of flame to standard size.
Note: When igniting, dispose the air in the tube and then adjust the valve slowly, carefully
control the size of flame within stated range, so as to avoid fire hazard.
III.Operation
3.1 Commissioning
3.1.1 Power supply
Turn on “Power” switch and the light works.
Liquid return joint and
pipe
Gas inlet
In/Out liquid joint with
valve

3.1.2 Voltage adjustment
Turn the voltage adjusting wheel clockwise to the end, the pointer will be from 0 to maximum,
otherwise the pointer will be from maximum to 0.
3.1.3 Choose stirring rate
Turn on “RUN”, stir motor starts working. Observe if the stirrer blade is flexible and if stirring is even.
Turn stir adjusting wheel to adjust stirring rate from 0-40 roll/min, for example, if you need adjust to
30 roll/min, you can rotate to 7.5 scale point.
3.1.4 Igniting
Push down “IGNITION” button on control panel, shutter slides and door opens, igniter descends to
test cup’s vapor space. When igniting, stir motor automatically stops.
3.1.5 Input medium
If flash point of sample around 15℃, user can use icy water as medium, and if flash point around
40℃, water with normal temperature can be used. Switch off the water inlet cover and funnel the
medium into the bath. Slow the speed in the late of stage and observe if any liquid flow from liquid
return pipe. Pay attention, if too fast, medium might flow out from thermometer hole or water inlet
hole.
If flash point of sample at range of -30℃to 15℃, additional cooling bath should be used
Connect intake pipe to In/Out liquid joint, connect liquid return pipe to overflow pipe and fix well.
Open the stop valve slightly, and then open cooling bath, input medium slowly and observe if any
liquid flow out. If observed, shut cooling bath and valve immediately.
Note: Circulating rate must not too fast, otherwise cold liquid might flow out and hurt operator.

3.2 Operation
3.2.1 Preparation
After successful commissioning, instrument can start normal operation. For testing operation
procedures, see ASTM test method standard.
3.2.2 Heating rate
Load sample as requirement, turn on “POWER” and “RUN”: button, adjust voltage dial to heat the
sample, observe thermometer reader, and adjust the voltage suitably so as to meet the test
requirement.
Temperature rising rate: 1℃/min
3.2.3 Test condition
Get through the gas source and ignite the ever-light flame and pilot flame, adjust the size of pilot
flame to 3mm-4mm, and adjust ever-light flame to a little bigger. Press “FIRE” for 1 second, the pilot
flame will be descended.
3.2.4 When test operation is complete, adjust voltmeter back to “0”, turn off “RUN”, switch off gas
source, remove all liquid medium in the bath.
