ASTM E102/E102M-93 (R2021) pdf free download.Standard Test Method for Saybolt Furol Viscosity of Bituminous Materials at High Temperatures.
1.1 This test method covers the empirical procedures for determining the Sayholt Furol viscosities of bituminous materials at specified temperatures between 120 and 240 °C j248 and 464 °F].
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 nonconformance with the standard.
3. Terminology
3. 1 Definitions:
3. 1 . 1 Furol—an acronym of “fuel and road oils.”
3. 1 .2 Saybolt Furol viscosity—the corrected efflux time in seconds of 60 mL of sample (lowing through a calibrated Furol orifice under specified conditions. The viscosity value is reported in Saybolt Furol seconds, abbreviated SFS, at a specified temperature.
4. Summary of Test Method
4.1 The efflux time in seconds of 60 mL of sample. flowing through a calibrated orifice, is measured under carefully controlled conditions. The time is corrected by an orifice factor and reported as the viscosity of the sample at that temperature.
5. Significance and Use
5.1 This test method is useful in characterizing certain bituminous materials, as one element in establishing uniformity of shipments and sources of supply.
5.2 This test method is an extension of Test Method D88/D88M.
6. Apparatus
6. 1 Saybolt Furol Viscometer and Bail,, as shown and described in Test Method D8/D88M, Fig. 1 and Annex Al. An external heater may also be used, hut if so, it shall be more than 51 mm [2 in.1] from the viscomcter. An aluminum-block, constant-temperature bath is also acceptable, and no stirring device is required with this type of bath.
6.2 Displacement Ring, as shown in Fig. 1, constructed of the same corrosion-resistant metal as the viscometer.
6.3 Cover—A metal cover for the viscometer, cylindrical with a flat top, approximately 57 mm [2½ in.1 in diameter and 7 mm [¼ in.] deep (Note 1). One hole slightly larger than the diameter of a viscosity thermometer shall be drilled in the center of the cover, and two smaller holes to permit the vertical rods of the displacement ring to pass through the cover.
6.4 Thermometer Support, as shown in Test Method D88/ D88M, Fig. 3.ASTM E102/E102M pdf download.
