Iodine Number (ASTM D4607)
This test method covers the determination of the relative activation level of unused or reactivated carbons by adsorption of iodine from aqueous solution. The amount of iodine absorbed (in milligrams) by 1 g of carbon using test conditions listed herein is called the iodine number.
Methylene Blue (JIS K 1474 2014)
Butane Activity (ASTM D5742 – 95)
Substitute for determining Carbon Tetrachloride Activity
This test method covers determination of the activation level of activated carbon. Butane activity (BA) is defined herein as the ratio (in percent) of the mass of butane adsorbed by an activated carbon sample to the mass of the sample, when the carbon is saturated with butane under the conditions listed in this test method.
Ash Content (D 2866 – 94)
This test method describes a procedure for the determination of total ash content of activated carbon.
Hardness Test (D 3802 – 79)
This test method provides a procedure for determining the ball-pan hardness number of granular activated carbons. For the purpose of this test, granular activated carbons are those having particles 90 % of which are larger than 80 mesh (180 µm) as determined by Test Method D 2862.
Moisture Content (D 2867 – 04)
This test method determines the moisture content of activated carbon. 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 150°C).
