Abstract: Taking tung oil sample as the objective, refractive index and content of free fatty acids were tested. The homogeneity of the sample was judged by the obtained data through F determination. The testing result showed that the homogencity test of tung oil sample can be used for the comparison test of interlaboratory proficiency.

Key words: proficiency test, tung oil, homogeneity test
