Organization: ASTM International
Publication Date: 15 April 2009
Status: inactive
Page Count: 4
ICS Code (Waxes, bituminous materials and other petroleum products): 75.140
significance And Use:

This test method is useful as one element in establishing the uniformity of shipments.

Viscosity is also valuable for rheological characterization of binder pitches. Binder pitch imparts... View More

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·s) and one millipascal second (mPa·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.
