An International program was completed in 1983 for standard D445, in which tests were carried out on 14 opaque oils and 1 clear oil. The tests were carried out at three different temperature's, namely 50, 80 and 100°C. The corresponding numbers of aboratories which completed tests at these temperatures were 15, 35 and 37.
