Standard Test Method for Distillation of Pitch
SCOPE
1.1 This test method covers a distillation test for pitch applicable whenever the amount of distillate below 270°C is less than 2.0% by this test method.
1.2 The values stated in SI units are to be regarded as the standard. The values given 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.
