Significance and Use | |
4.1 The experimental procedures and physical constants provided by this test method, when used in conjunction with Test Method D1015, allow the determination of the purity of the material under test. A knowledge of the purity of these hydrocarbons is often needed to help control their manufacture and to determine their suitability for use as reagent chemicals or for conversion to other chemical intermediates or finished products. |
