ASTM D139-12
(Test Method)Standard Test Method for Float Test for Bituminous Materials
Standard Test Method for Float Test for Bituminous Materials
SIGNIFICANCE AND USE
4.1 The float test characterizes the flow behavior or consistency of certain bituminous materials.
4.2 This test method is useful in determining the consistency of bitumen as one element in establishing the uniformity of certain shipments or sources of supply.
SCOPE
1.1 This test method covers the float test for bituminous materials.
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 Warning—Mercury has been designated by 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.epa.gov/mercury/faq.htm) for additional information. Users should be aware that selling mercury or mercury-containing products, or both, in your state may be prohibited by state law.
1.4 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. For a specific precaution statement, see 6.1.
