ASTM D3245 Test Method for Pumpability of Industrial Fuel Oils
1. Scope
1.1 This test method is intended for use on petroleum fuel oils, such as those covered in Specification D396 Grade No 4(Light), 4, 5(Light), 5, and 6, or similar fuels.
1.2 The values stated in SI units are to be regarded as standard. The values in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Terminology
3.1 Definitions:
3.1.1 handling point - an indication of the minimum temperature to which an oil should be heated in any part of the suction or delivery line of an oil-handling installation when the installation is operating. If the storage tank does not contain an outflow heater, this temperature is necessarily the minimum oil storage temperature.
3.1.2 It is defined as that temperature at which the oil has an apparent viscosity of 0.6 Pa•s (6 P), at a rate of shear of 9.7 s(-1), when cooled and tested under prescribed conditions.
3.1.3 storage point - an indication of the minimum temperature to which an oil should be heated in any part of an oil-handling installation when starting up after a shutdown. It is also an indication of the minimum temperature at which the oil should be stored in a tank fitted with an outflow heater.
3.1.4 It is defined as that temperature at which the oil has an apparent viscosity of 2.5 Pa•s (25 P), at a rate of shear of 9.7 s(-1), when cooled and tested under prescribed conditions.
