Full Description

1.1This test method covers determination of the penetration of semi-solid and solid bituminous materials.

1.2The needles, containers, and other conditions described in this test method provide for the determinations of penetrations up to 500.

Note 1:See the section on Penetration of Test Methods D244 for information and precision and bias on testing emulsion residue.

1.3The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.

1.4The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and gures) shall not be considered as requirements of the standard.

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.

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.
