Petroleum and related products from natural or synthetic sources. Determination of pour point. Automated linear cooling method | Status: Current

1 Scope This document specifies a method for determining the pour point of petroleum products by means of automatic equipment for detecting movement of the test specimen using a linear cooling technique. A separate procedure suitable for the determination of the lower pour point of fuel oils, heavy lubricant base stock, and products containing residual fuel components is also described. The procedure described in this document is not suitable for crude oils. Test results from this method can be determined in either 1 °C or 3 °C testing intervals

NOTE The equipment referenced in this method can also generate results at 1 °C testing intervals, which is an acceptable alternative procedure, but for which precision and bias have not been determined.
