DETERMINATION OF FLASH POINT - RAPID EQUILIBRIUM CLOSED CUP METHOD.
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).
For specifications and regulations, procedures A or B are routinely used (see 10.1.1).
