介绍
This document includes three programs (A, 乙和丙), covering flash flash and the determination of flash point. Quick balance program A and B flash flash point and flash point can be determined respectively. Nonequilibrium program C uses an automatic test cup temperature control for flash point determination.

国际标准化组织 1516 和ISO 1523 is a closed cup balance test method, can consider when choosing method.

The equipment specified in this document can determine similar test results using A faster procedure A or B and a smaller test section (2ml or 4ml) than those required in ISO1516 or ISO 1523. 此外, the equipment in this document can be easily carried so that it is suitable for field testing, as well as for regular use in the laboratory. Cooperation work shows that the results obtained by these methods is comparable. Procedure C is based on test methods IP 534 and ASTM D7236.

The interpretation of flash point results obtained for solvent mixtures containing halogenated hydrocarbons should be considered with caution, as these mixtures can produce anomalous results.

A limited study showed that when used with this document electric igniter, some coating may produce higher flash point.

Flash point for transportation, 贮存, handling and safety laws and regulations, defined as “易燃的” 和 “flammable materials” the classification of attributes. Each particular statute gives a precise definition of the categories.

Flash point in the relatively non-volatile or non-flammable materials of high volatile materials. Flash point testing is often used as a preliminary step for other studies of unknown material composition.

Unfavorable to may not be stable, easy to break down, or explosive materials for determination of flash point. That is to say, unless previously identified in this method the required temperature range heating contact with metal parts of the flash point of a specified number of such material will not cause decomposition, explosion or other adverse effects.

The flash point is not a constant physicochemical property of the material under test. It is a function of the device design, the condition of the device used, and the operating procedures performed. 所以, flash points can only be defined according to standard test methods, and there is no guarantee of a generally valid correlation between the results obtained by different test methods or with the specified different test equipment.

ISO/TR 29662 also provides useful advice in conducting flash point tests and interpreting the results.

1 范围
This document introduces the three procedures (A, 乙和丙), covering flash flash and the determination of flash point.

Rapid balance procedures A and B are suitable for flash edge free and flash point testing of paints, including waterborne coatings, 清漆, paints and varnishes binders, 粘合剂, 溶剂, petroleum products (including aviation turbines), diesel and kerosene fuels, fatty acid methyl esters and related products, in a temperature range of -30 °C 至 300 ℃. Quick balance procedure used to determine the product under the specified temperature will blink (flash without A flash program) or the flash point (乙) 样本的. This document is also applicable to determine the flash point of fatty acid methyl ester (FAME) when used in conjunction with A flash detector (A.1.6). The effectiveness of precision is shown in Table 2.

Non-equilibrium program C is suitable for petroleum products, including aviation turbines, diesel and kerosene fuels and related petroleum products, in a temperature range of -20 °C to 300°C. The off-balance program automatically determines the flash point. Accuracy has been determined in the range of 40 °C 至 135 ℃.

About the norms and regulations, usually use the program A or B (看 10.1.1).

3 术语和定义
就本文件而言, 以下术语和定义适用.

ISO 和 IEC 在以下地址维护标准化术语数据库:

– IEC电子百科全书: 可以在 electropedia.org/ 上找到

3.1 平衡
A condition in a flash point test method where the test section and the steam above the test section are at the same temperature when the ignition source is applied

笔记 1: This situation cannot be fully realized in practice, as the temperature may not be uniform throughout the test section, and the test covers and blinds on the equipment can be colder or warmer.

例子: Procedures A and B in this document, 国际标准化组织 1516 和ISO 1523.

3.2 Fatty acid methyl ester
reputation

Fuel consisting of monoalkyl esters of long-chain fatty acids derived from vegetable oil or animal fat, designated as B100 or biodiesel (100%)

笔记 1: FAME is specified in specifications such as EN 14214 and ASTM D6751.

3.3 Flash No flash
The ignition source is applied at the specified temperature of the test section, measured in the specified manner and adjusted for changes in atmospheric pressure of 101,3 kPa to determine whether the vapor of the test section is ignited and whether the flame propagates over the liquid surface under the specified test conditions

3.4 闪点
试验段最低温度, 根据大气压力的变化进行调整 101,3 千帕, at which the application of an ignition source under the specified test conditions would cause the vapor of the test section to ignite and the flame to spread over the liquid surface

3.5 Non-equilibrium
A condition in a flash point test method in which the test section and the steam above the test section are not in temperature equilibrium when the ignition source is applied

笔记 1: This situation is mainly due to the fact that the test section is heated at a constant prescribed rate and the steam temperature lags behind the test section temperature.

例子: Program C in this document, 国际标准化组织 2719 和ISO 13736.
