ASTM D4930-94(2004)e1
(Test Method)Standard Test Method for Dust Control Material on Calcined Petroleum Coke
Standard Test Method for Dust Control Material on Calcined Petroleum Coke
SCOPE
1.1 This test method covers the determination of the amount of material applied to calcined coke to control dust associated with coke handling and transportation.
1.2 This test method is limited to those materials that are soluble in a solvent that can be used in a Soxhlet extraction type of apparatus such as methylene chloride (dichloromethane).
Note 1—Methylene chloride is the most popular solvent for removing dust control oil at the time this procedure is being written. Toluene and methyl chloroform, however, have been used with equal results on all cokes tested which have included only those sprayed with aromatic or waxy materials.
1.3 The values stated in SI units are to be regarded as 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. For specific hazard statements, see Section 8.
