Description

ASTM D5018-89-Reapproved2004

Historical Standard: Standard Test Method for Shear Viscosity of Coal-Tar and Petroleum Pitches

ASTM D5018

Scope

1.1 This test method covers the determination of the apparent shear viscosity of coal-tar and petroleum-based pitches having a Mettler softening point (SP) range of approximately 95 to 120°C.

1.2 This test method is applicable only for rotational viscometers.

1.3 Since this test method is based on theoretical grounds, strict adherence to details of the procedure is necessary to comply with the theoretical requirements.

1.4 The values stated in conventional units (centipoise) are to be regarded as the standard. The SI unit is the pascal second (Pa[dot]s) and one millipascal second (mPa[dot]s) = one centipoise (cps); centipoise is in cgs units.

1.5 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. Specific hazard statements are given in Section 7.
