Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 510-1983 "Petroleum product freezing point determination method". Compared with GB/T 510-1983, except for editorial changes
The main technical changes are as follows.
--- Refined the scope of application of this standard, and supplemented the scope of application of automatic micro-condensation point tester (see Chapter 1, 1983 edition)
1 paragraph);
--- Added references to normative references, terms and definitions, sampling, etc. (see Chapters 2, 3 and 7);
--- Expanded the use of coolant, as long as it is any liquid and material that can cool the sample to the specified temperature of the test
As a coolant for this standard (see 5.2.1, 1983 edition 2.2.1);
--- Added the relevant content of the automatic micro-condensation point tester, including instrument requirements, test preparation, test procedures, results representation and precision
Degree, etc., but it is only applicable to the determination of samples containing no diesel fractions of additives (see Chapters 1, 6.2, 8.3, 9.2, 10.3 and 11.2);
--- Added the provisions of the controversial arbitration test based on the results of the manual instrument's freezing point test.
This standard is proposed and managed by the National Petroleum Products and Lubricants Standardization Technical Committee (SAC/TC280).
This standard was drafted. Petrochemical Research Institute of China Petroleum and Chemical Corporation, Dalian Petroleum Instrument Co., Ltd.

Petroleum product freezing point measurement
Caution - Personnel using this standard should have practical experience in formal laboratory work. This standard does not indicate all possible security questions.
question. It is the responsibility of the user to take appropriate safety and health measures and to ensure compliance with the conditions set by the relevant national regulations.
1 Scope
This standard specifies the method for determining the freezing point of petroleum products.
This standard applies to petroleum products such as liquid fuels (such as diesel, biodiesel blended fuels) and lubricants. Automatic micro-condensation in this standard
The point meter is only suitable for the determination of samples without additive diesel fractions.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Solidification point
The sample is cooled under specified conditions until the maximum temperature at which the liquid level stops moving, expressed in °C.
4 Method summary
The sample was placed in a prescribed test tube and cooled to the desired temperature. The test tube was tilted to 45 ° with the horizontal for 1 min, and the liquid level was observed.
No movement, the highest temperature when the liquid surface does not move is used as the freezing point of the sample.
