8、e.This mixture is allowed to settle in a graduated tube and thefoots content is determined volumetrically.5.Significance and Use5.1 This test method provides an empirical measure of theamount of solid impurities present in raw linseed oil.Theimpurities are usually suspended in the oil.Addition of th
9、ereagents stratifies the impurities in a layer that is measuredvolumetrically.After addition of the reagents,a period of timeis provided to allow the impurities to stratify.The test methodis empirical since the volume of the impurity stratum willincrease over a period of time due to the hydration of
10、 theimpurities.5.2 After heating a sample of the oil to 65C,it is dividedinto two parts.One part is cooled to about 25C and the otherto 0C before the test is run.The test results run on the twosamples are known as the heated foots and chilled footsrespectively.6.Apparatus6.1 Beakers,150-mL,made of c
