1) abbreviated deg F, example 16 = 1600 deg F = 875 deg C
2) test temperature at which no more than 2 % permanent linear change may occur after 24 hours.
3) upper limit of median bulk density of group L. In each group of the L class the bulk density is a property used only for differentiation and is indicated with two digits after the decimal point.
