(Test Method)Standard Test Methods for Carbon Black—Sulfur Content
Standard Test Methods for Carbon Black<span class='unicode'>—</span>Sulfur Content
SIGNIFICANCE AND USE
The total sulfur content of a carbon black is useful in determining whether a material meets a customer’s specifications, providing data for performing a sulfur material balance around a process for environmental monitoring and reporting, and 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:
Sections Test Method AHigh-Temperature Combustion With In-
frared Absorption Detection Procedures6 to 13 Test Method BX-Ray Fluorescence14 to 19
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.
