Standard Test Method for Pumpability of Industrial Fuel Oils
SCOPE
1.1 This test method is intended for use on petroleum fuel oils, such as those covered in Specification D 396 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.
