ASTM D5 Standard Test Method for Penetration of Bituminous Materials
1. Scope
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 - For guidance in preparing and testing emulsion residue specimens for this test method, please refer to Section 35 of Test Method D244.
1.3 The values stated in SI units are to be considered standard.
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.
