Full Description

1.1 These test methods provide three procedures for the determination of the moisture content of activated carbon. The procedures may also be used to dry samples required for other tests. The oven drying and moisture balance methods are used when water is the only volatile material present and is in significant quantities, and the activated carbon is not heat sensitive (some activated carbons can ignite spontaneously at temperatures as low as 150 C). The xylene extraction method is used when a carbon is known or suspected to be heat sensitive or to contain miscible organic compounds instead of or in addition to water. The interferences posed by miscible inorganic compounds has not been determined. The oven drying method described in these test methods may be used as the reference for development of instrumental techniques for moisture determination in activated carbon. 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.
