1、Designation: D1510 11Standard Test Method forCarbon BlackIodine Adsorption Number1This standard is issued under the fixed designation D1510; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in par
2、entheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This test method covers the determination of the iodineadsorption n
3、umber of carbon black.1.1.1 Method A is the original test method for this determi-nation and Method B is an alternate test method usingautomated sample processing and analysis.1.2 The iodine adsorption number of carbon black has beenshown to decrease with sample aging. New SRB HT IodineStandards hav
4、e been produced that exhibit stable iodinenumber upon aging. One or more of these SRB HT IodineStandards are recommended for daily monitoring (x-charts) toensure that the results are within the control limits of theindividual standard. Use all SRB HT Iodine Standards forstandardization of iodine tes

10、lack.4. Significance and Use4.1 The iodine adsorption number is useful in characterizingcarbon blacks. It is related to the surface area of carbon blacksand is generally in agreement with nitrogen surface area. Thepresence of volatiles, surface porosity, or extractables willinfluence the iodine adso
