ASTM D97-12

This test method covers and is intended for use on any petroleum product. A procedure suitable for black specimens, cylinder stock, and nondistillate fuel oil is described in section 8.8. The cloud point procedure formerly part of this test method now appears as Test Method D2500. Currently there is no ASTM test method for automated Test Method D97 pour point measurements. 1.3 Several ASTM test methods offering alternative procedures for determining pour points using automatic apparatus are available. None of them share the same designation number as Test Method D97. When an automatic instrument is used, the ASTM test method designation number specific to the technique shall be reported with the results. A procedure for testing the pour point of crude oils is described in Test Method D5853.
