ASTM D2867-17 活性炭湿度的标准试验方法

4.1 The moisture content of activated carbon is often required to define and express its properties in relation to the net weight of the carbon. 4.2 The moisture content of activated carbon packed in typical shipping containers will usually increase during transportation and storage. Users of activated carbon in applications where low moisture content is important should be aware of this effect. 1.1 These test methods provide two procedures for the determination of the moisture content of activated carbon.2 The procedures may also be used to dry samples required for other tests. The oven drying method is 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 1508201;°C). The xylene extraction method is used when a carbon is known or suspected to be heat sensitive or to contain nonwater-miscible organic compounds instead of or in addition to water. 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 and health 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.

Standard Test Methods for Moisture in Activated Carbon

EN 16849:2016 沥青和沥青粘合剂.沥青乳液中水含量的测定.干燥平衡法

This European Standard specifies a quick method for determining, by evaporation, the water content of bituminous road emulsions, with or without polymer added. For bituminous emulsions without flux oil, bituminous emulsions containing vegetal flux oil, and bituminous emulsions containing up to 1,5 % mass of mineral flux oil in the emulsion, this European Standard, according to the selected operating conditions, is considered as an alternative method to the reference methods EN 1428 and EN 1431. Above a mineral flux oil content of 1,5 % by mass, depending on the volatility of the flux oil:- the present method can be used if the user can prove its reliability in comparison to EN 1428 or EN 1431; - the present method can only be used by correcting the result by means of a previously established correlation with the reference method EN 1428 or EN 1431. NOTE Polymer modified emulsions can behave differently in the test than unmodified emulsions; in case of doubt, the method is checked against EN 1428 or EN 1431. In case of dispute, the water content should be determined according to EN 1428 or EN 1431. WARNING - The use of this European Standard can involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
