1.1This 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 °C to 120 °C (see Test Method D3104).
1.2This test method is applicable only for rotational viscometers.
1.3Since this test method is based on theoretical grounds, strict adherence to details of the procedure is necessary to comply with the theoretical requirements.
1.4The values stated in SI units are to be regarded as standard.
1.4.1Exception—The values stated in conventional units (centipoise) are to be regarded as the standard for viscosity measurement only. The SI unit is the pascal second (Pa·s) and one millipascal second (mPa·s) = one centipoise (cP); centipoise is in cgs units.
1.5This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 8.
1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
