ASTM D3409/D3409M-93(2016)e1
(Test Method)Standard Test Method for Adhesion of Asphalt-Roof Cement to Damp, Wet, or Underwater Surfaces
Standard Test Method for Adhesion of Asphalt-Roof Cement to Damp, Wet, or Underwater Surfaces
SIGNIFICANCE AND USE
3.1 This test method offers a means of evaluating the adhesive properties of asphalt roofing cements used to repair roofs under adverse conditions. Weathered roof surfaces are easily coated with asphalt roofing cements when they are dry, however when wet or during a rain, asphalt roofing cements may not adhere readily to water-wet surfaces such as metal flashings or asphalt roll roofing. The flamed metal lids used in this test method simulate weathered roof surfaces.
SCOPE
1.1 This test method covers the determination of the adhesion of asphalt roofing cements to damp, wet, or underwater surfaces.
1.2 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 non-conformance with the standard.
1.3 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.

2. Summary of Test Method
2.1 A metal lid is covered with a coating of asphalt roofing cement and immersed in water. A similar metal lid which has been
flamed and wet with water is pressed on the asphaltic surface. The degree of adhesion is evaluated by estimating the percentage
of area covered by the cement on the water-wet flamed metal lid.
