本文件描述了三个程序（A、B和C），包括测定闪点、无闪点和闪点。快速平衡程序A和B适用于涂料（包括水性涂料、清漆、涂料和清漆用粘合剂、粘合剂、溶剂、石油产品（包括航空涡轮机）、柴油和煤油燃料、脂肪酸甲酯和相关产品）在-30℃温度范围内的无闪光和闪点测试°C至300°C。快速平衡程序用于确定产品在指定温度下是否会闪蒸（闪蒸无闪蒸程序？a）或样品的闪点（程序？B）。与闪光检测器（A。1.6），本文件也适用于测定脂肪酸甲酯（FAME）的闪点。精度的有效性见表2.非平衡程序C适用于石油产品，包括航空涡轮、柴油和煤油燃料以及相关石油产品，温度范围为-20℃°C至300°C。非平衡程序自动确定闪点。精度已在40°范围内确定°C至135°C°C。对于规范和法规，通常使用程序A或B（见10.1.1）。

This document describes three procedures (A, B and C) covering determinations of flash no-flash and flash point.Rapid equilibrium procedures A and B are applicable to flash no-flash and flash point tests of paints, including water-borne paints, varnishes, binders for paints and varnishes, adhesives, solvents, petroleum products including aviation turbine, diesel and kerosene fuels, fatty acid methyl esters and related products over the temperature range –30 °C to 300 °C. The rapid equilibrium procedures are used to determine whether a product will or will not flash at a specified temperature (flash no-flash procedure A) or the flash point of a sample (procedure B). When used in conjunction with the flash detector (A.1.6), this document is also suitable to determine the flash point of fatty acid methyl esters (FAME). The validity of the precision is given in Table 2.Non-equilibrium procedure C is applicable to petroleum products including aviation turbine, diesel and kerosine fuels, and related petroleum products, over the temperature range –20 °C to 300 °C. The non-equilibrium procedure is automated to determine the flash point. Precision has been determined over the range 40 °C to 135 °C.For specifications and regulations, procedures A or B are routinely used (see 10.1.1).
