ASTM D1619-03

Standard Test Methods for Carbon Black—Sulfur Content

SIGNIFICANCE AND USE
The total sulfur content of a carbon black is useful in calculations for reconstructing a rubber composition from analytical data.
SCOPE
1.1 These test methods cover the determination of the sulfur content of carbon black. The following test methods are included:SectionsTest Method AHigh-Temperature Combustion With In-frared Absorption Detection Procedures6 to 13Test Method BX-Ray Fluorescence14
1.2 The values stated in SI units are to be regarded as 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.
