Scope of standard The viscosity at 60°C (140°F) characterizes flow behavior and may be used for specification requirements for cutbacks and asphalt binders. 1.1 This test method covers procedures for the determination of viscosity of asphalt binder (bitumen) by vacuum capillary viscometers at 60°C (140°F). It is applicable to materials having viscosities in the range from 0.0036 to over 20 000 Pa · s (0.036 to over 200 000 P). Note 1-This test method is suitable for use at other temperatures, but the precision is based on determinations on asphalt binders at 60°C (140°F). 1.2 Warning-Mercury has been designated by the United States Environmental Protection Agency (EPA) and many state agencies as a hazardous material that can cause central nervous system, kidney and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPA's website-http://www.e 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. |
