3.1 The sulfur content can be used to characterize a silane or an admixture of silane and carbon black. It depends mainly on the average length of the sulfur chain.

1.1 These test methods cover the determination of the sulfur content of silanes, or of admixtures of silane and carbon black, of the type bis-(triethoxysilylpropyl)sulfane. The following test methods are included:

Test Method A: Combustion in an Oxygen Flask and Subsequent
 Titration of Sulfate

Test Method B: High-Temperature Combustion with Infrared
 Absorption Detection

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
