Cleveland flash point tester fuhe GB/T3536-2011 petroleum product flash point and ignition point method (Cleveland open cup method) to determine the flash point and ignition point of all petroleum products except for fuel oil and products with a flash point below 79 °C.
Cleveland flash point tester in accordance with GB/T3536-2011 [petroleum flash point and ignition point method (Cleveland open cup method)] to determine the flash point of all petroleum products except for fuel oil and products with a flash point below 79 °C The ignition point is also applicable to the international standard ISO2592-1973 [Purification and Flash Point Determination of Petroleum Products (Cleveland Open Cup Method)].
SYD-3536 Cleveland flash point tester main technical parameters and specifications:
The instrument consists of Cleveland oil cup, igniter, electric furnace, thermometer, etc. The main specifications are as follows:
1. Cleveland oil cup: The material is H62, and the inner diameter is 63.5±0.5. There is a scribe line at the inner wall.
2. Ignition: consists of intake pipe, air flow control valve and flame comparison ball, according to the test method,
The flame can be adjusted to a 4mm spherical flame.
3, electric furnace: consists of 200V-450W tubular heater and circuit body, according to the use requirements, through
The electric furnace heating regulator controls the heating rate.
4, thermometer: 400 ° C, the index is 2 ° C, technical requirements in line with GB514-83 [Petroleum product trial
The provisions of the technical conditions of liquid thermometers.
5. Electrical device: consists of a set of electronic voltage regulating circuit and semi-automatic igniter device, including two-way thyristor,
Bidirectional diodes, resistors, capacitors, indicator lights, wave switches, potentiometers, self-locking push button switches,
Reversible motor, micro switch and so on.
Third, the use of instructions:
1. This instrument is used in accordance with GB/T3536-83 [Petroleum Product Flash Point and Burning Point Measurement Method (Cleveland Open Cup Method)].
2. Pour the test cup into the Cleveland oil cup, fill the line, place the oil cup on the electric stove, adjust the height of the igniter device and the thermometer, adjust the size of the flame, and do all the preparations.
3. According to the wave switch, the power indicator light is turned on, and the capacitor furnace starts to heat up. According to the provisions of GB/T3536-83, the temperature rise speed is controlled by the potentiometer, and the flash point is expected.
At the first 28 °C, press the self-locking button switch, the ignition rod is ignited. If there is no flash point phenomenon, after heating up to 2 °C, press the self-locking button switch, the ignition rod will ignite in the opposite direction, and the time required to pass the test flame each time approximately
One second. Record the temperature on the thermometer when a flash point appears at any point on the oil level. As a flash point. After the test is finished, clean it and cut off the power.
Fourth, note:
1. For a clear observation of the flash point, try to avoid places where the wind is sheltered and the light is dark.
2. When the power supply is heated by the electric furnace, pay attention to the safety protection of the electrical components.
