Doplňující informace
| 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. 4.2 The stain index is related to the thermal stability of the asphalt. Higher stain index values indicate lower stability and greater tendency for staining. 4.3 Use this procedure to determine the staining tendency of asphalt and to compare the results against a material for which the staining tendency is known. |

| 1. 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. 1.3 The values stated in SI units
are to be regarded as the standard. The values in parentheses are
for information only.
1.4 This standard does not purport to address 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. |
