闪点的测定——用小型闭杯试验机测定无闪点和闪点的方法

[中文适用范围]： 本文件描述了涵盖闪点、无闪点和闪点测定的三个程序（A、B 和 C）。 快速平衡程序A和B适用于油漆的闪点、无闪点和闪点测试，包括水性油漆、清漆、油漆和清漆的基料、粘合剂、溶剂、石油产品（包括航空涡轮机、柴油和煤油燃料、脂肪族燃料）酸甲酯及相关产品的温度范围为 –30 °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）。 当与闪点检测器（A.1.6）结合使用时，本文件也适用于测定脂肪酸甲酯（FAME）的闪点。 精度的有效性如表 2 所示。 非平衡程序 C 适用于温度范围 –20 °C 至 300 °C 的石油产品，包括航空涡轮机、柴油和煤油燃料以及相关石油产品。 自动非平衡程序以确定闪点。 精度在 40 °C 至 135 °C 范围内确定。 对于规范和规定，通常使用程序 A 或 B（见 10.1.1）。 [外文原描述]： 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).
