Foreword
This standard is identical with the German national standard DIN51794.2003 "Petroleum products - Determination of auto-ignition temperature" (in English).
This standard is managed by the National Standardization Technical Committee chemicals dangerous (SAC/TC251) and focal points.
This standard was drafted. China Research Institute of Petroleum Corp. Petrochemical, Tianjin Entry-Sinochem
Institute of Chemical standardization.
The main drafters of this standard. YANG Ting-ting, Chen Jie, Guo Tao, Zhang Jun Xi, Zhou Wei.
This standard is the first release.
Introduction
Self-ignition temperature is not constant physical and chemical fuel, but depends on the characteristics under certain circumstances the main condition factors. May be due
Measurement methods to assess exposure to heat the surface of flammable liquids and gases flammability level of this standard for the establishment of appropriate electrical and non-fire resistant
Security measures for electrical equipment to provide evidence.
For mixtures, in particular oil, if air enters the combustion vessel after the addition of the sample, the sample in the container from below
Lower ignition temperature (measured by the standard available) may also be observed further combustion phenomenon. "After the spontaneous combustion temperature" may be lower than the measured temperature of spontaneous combustion
Of more than 100 ℃. For security reasons, when measured after the spontaneous combustion temperature must be examined whether there is auto-ignition temperature is determined [1].
Petroleum products - Determination of auto-ignition temperature
1 Scope
This standard specifies the method for determination of flammable liquids and gases, petroleum products and mixtures between 75 ℃ ~ 650 ℃ spontaneous combustion temperature.
Auto-ignition temperature measurable combustibles in contact with hot objects, and the combustion tends to occur under conditions mixed with the air, and so on into fuel
Line security classification.

3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Under the conditions specified in this standard, fuel begins to burn lowest temperature.
3.2
In the combustion vessel, and the mixture happened accompanied by a significant enhancement of the flame or deflagration reactions within 5min may occur.
3.3
Sample starts burning time from the sample into the container to the combustion.
NOTE. lights the fire lag from a few tenths to a few minutes, but usually less than 3min.
4 units
Reports auto-ignition temperature of the unit. ℃.
5 Summary of Method
In each combustion test, a small quantity of the sample into the opening combustible Erlenmeyer flask. The flask was heated with an electric furnace, and the heating temperature was observed in
Whether the sample combustion occurs degrees. Finally, the residue in the flask blown with air vaporizable components.
