Significance and Use
4.1 In specific end uses, the amount and composition of the ash may influence the capabilities and certain desired properties of activated carbon.
4.2 Other automated methods for determination of ash content, such as combusting the carbon in a thermogravimetric analyzer (TGA) in flowing air or oxygen, can be used in place of this test method. A suitable method is described in Test Methods . For determination of the ash content of activated carbon, follow the procedure in 13.5.3 of Test Methods , with the exception that the furnace temperature in 13.4.3 shall be 650 ± 25 °C. The muffle furnace method shall be considered the reference test method.
1.1 This test method describes a procedure for the determination of total ash content of 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.
