Basic dataStandard ID: GB/T 21860-2008 (GB/T21860-2008)Description (Translated English): Liquid chemicals -- Test method for the autoignition temperature Sector / Industry: National Standard (Recommended) Classification of Chinese Standard: A80 Classification of International Standard: 13.300 Word Count Estimation: 10,177 Date of Issue: 2008-05-12 Date of Implementation: 2008-09-01 Quoted Standard: ASTM D2883 Adopted Standard: ASTM E659-1978 (2005), IDT Regulation (derived from): Announcement of Newly Approved National Standards 2008 No. 8 (No. 121 overall) Issuing agency(ies): General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, Standardization Administration of the People's Republic of China Summary: This standard applies to liquid chemicals at atmospheric pressure in a container to be heated uniformly hot flame, cold flame ignition temperature determination. This standard applies to measure and describe the raw materials, products in the test chamber under controlled conditions, the reaction after heat or flame, and can not be used to evaluate the actual fire conditions in fire hazard or risk. However, the results of this test method can be used as an evaluation of a particular fire hazard assessment of a variety of factors. GB/T 21860-2008: Liquid chemicals -- Test method for the autoignition temperature---This is a DRAFT version for illustration, not a final translation. Full copy of true-PDF in English version (including equations, symbols, images, flow-chart, tables, and figures etc.) will be manually/carefully translated upon your order.Liquid chemicals. Test method for the autoignition temperature ICS 13.300 A80 National Standards of People's Republic of China Standard Test Method for auto-ignition temperature of the liquid chemical Posted 2008-05-12 2008-09-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis standard is identical with the "Standard Test Method for auto-ignition temperature of the liquid chemical" ASTME659-78 (2005) (in English). The Standard Appendix A, Appendix B, Appendix C is informative appendix. This standard is managed by the National Standardization Technical Committee chemicals dangerous (SAC/TC251) and focal points. This standard is drafted by. Tianjin CIQ. Participated in the drafting of this Standard. China Research Institute of Petroleum Corp. Petrochemical, Shanghai CIQ. The main drafters of this standard. Xiongzhong Jiang, Chen Liqing, Jiang Wei, in Yanjun, Zhao Lihua, Zhou Lei. This standard is the first release. Test methods for self-ignition temperature of the liquid chemical 1) This standard is one way to test a variety of chemical risks, which are designed to be combined with other methods so that identification of the chemical under test Potentially dangerous under test conditions.1 ScopeThis standard applies to hot flame at atmospheric pressure in a uniformly heated vessel, cold flame self-ignition temperature determined that the liquid chemicals. Note. Under certain conditions, this standard also applies to the determination of the solid-state chemical autoignition temperature, such a requirement is solid chemicals below the test temperature conditions That has melted and is evaporated. This standard applies to measure and describe materials under controlled conditions in the test chamber, the reaction product after heat or flame, and not for Evaluation is a risk of fire or risk under actual fire conditions. However, the results of this test method can be used as combustion risk evaluation of specific use One of several factors to assess risk in nature.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. ASTMD2883 reaction liquid and solid material critical temperature measuring method 2) 1) This test method is authorized to ASTM E-27 Committee on hazard potential hazards of chemicals that the Subcommittee E27.04 on liquefied And ignition of flammable chemicals. The current version by 25 August 1978, issued in November 1978. 2) AnnualBookofASTMStandards, Vol05.02.3 Terms and DefinitionsThe following terms and definitions apply to this standard. 3.1 Burning begins. Flames and accompanying rapid rise in temperature of the gas phase. Therefore experimental observation because of some type, such as flame cold flame is very difficult to observe Carried out under conditions of complete darkness. 3.2 Substances in the air, there is no external source of ignition, such as spark, caused by the oxidation reaction of burning. 3.3 Under the experimental conditions of the test substance, the lowest temperature of spontaneous combustion phenomenon. Auto-ignition temperature, the spontaneous combustion temperature, combustion temperature itself, self combustion temperature, abbreviated as AIT and SIT. Obtained by the present method AIT, it is a substance at atmospheric pressure, not by means of an external energy source such as a spark or flame, resulting in the lowest temperature of the hot flame. It is a combustible mixture combustion Required to achieve the minimum temperature at this time the exothermic oxidation reaction exceeds the rate of heat loss to the environment causing the heat of combustion. 3.4 Weak, pale blue luminescence emitted substance or flame appears below the auto-ignition temperature (AIT) time. Note. The cold flame produced in hydrocarbon and oxygenated hydrocarbon saturated vapor and air mixture in the first part of a multi-stage ignition process. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 21860-2008_English be delivered?Answer: Upon your order, we will start to translate GB/T 21860-2008_English as soon as possible, and keep you informed of the progress.
