Standard Test Method for Staining Tendency of Asphalt (Stain Index)
description
Significance and Use
4.1 This test method measures the tendency for oil components to separate spontaneously from asphalt. The separation of oil components can cause staining in asphalt roofing products and adjacent materials in storage and use.
Scope
1.1 This test method covers the determination of the staining tendency of asphalt and the assignment of a stain index proportional to the extent of staining observed.
1.2 This test method is applicable to asphalts having ring-and-ball softening points of 85°C (185°F) or greater.
Note 1—This test method may be modified for use with other bituminous materials with softening points less than 85°C (185°F) by using a different temperature than specified in Section 7 by agreement of the interested parties. The report of results from such a test may cite this method but must clearly state the temperature employed in the exception and acknowledge that the interpretation of results in Section 9 and the precision and bias stated in Section 10 may not apply.
