D2008-91(2006) 1.1 This test
method covers the measurement of the ultraviolet absorption of a variety
of petroleum products. It covers the absorbance of liquids or the
absorptivity of liquids and solids, or both, at wavelengths in the
region from 220 to 400 nm of the spectrum. 1.2 The use of
this test method implies that the conditions of measurement-wavelength,
solvent (if any), sample path length, and sample concentration-are
specified by reference to one of the examples of the application of this
test method in the annexes or by a statement of other conditions of
measurement. 1.3 Examples of
the application of this test method are the determination of the
absorbance of white mineral oil, the absorptivity of refined petroleum
wax, and the absorptivity of USP petrolatum.
