Standard test methods for flash point by Setaflash closed tester
Methods are described for the determination of the flash point by a Setaflash closed tester. The procedures, which are applicable to petroleum products and other organic liquids, may be used to determine the actual flash point temperature of a sample or whether the product will or will not flash at a specified temperature. The apparatus is described in detail, and specifications for all parts of the apparatus are included. In the flash/no flash test, a specified volume of sample is introduced a syringe into the cup ot the selected apparatus that is set and maintained at the specified temperature. After a specific time, a test flame is applied, and an observation is made as to whether or not a flash occurred. In the other method for the determination of the finite or actual flash point, a specified volume of sample is introduced into the cup of the apparatus that is maintained at the expected flash point. After a specified time, a test flame is applied, and the observation is made whether or not a flash occurred. The cup is cleaned; the cup temperature is adjusted 5/sup 0/C, lower or higher depending on whether or not a flash occurred previously; and a fresh specimen is introduced and tested. This procedure is repeated until the flash point is established to the nearest 5/sup 0/C, and then to the nearest 1/sup 0/C, and finally to the nearest 0.5/sup 0/C if improved accuracy is desired.
