Significance and Use
5.1 The penetration test is used as a measure of consistency. Higher values of penetration indicate softer consistency.
Note 2: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
1.1 This test method covers determination of the penetration of semi-solid and solid bituminous materials.
1.2 The 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 for information and precision and bias on testing emulsion residue.
1.3 The 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.
1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and ﬁgures) shall not be considered as requirements of the standard.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This 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.
