ASTM D5/D5M − 13 Standard Test Method for Penetration of Bituminous Materials

ASTM D5/D5M − 13 Standard Test Method for Penetration of Bituminous Materials

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 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 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.

Significance and Use
5.1 The penetration test is used as a measure of consistency. Higher values of penetration indicate softer consistency.
