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 Go/No Go at a specified temperature (Go/No Go, procedure A) or the flash point of a sample (procedure B). When used in conjunction with the flash detector, this document is also suitable to determine the flash point of fatty acid methyl esters (FAME). 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. NPV Tech
