1.1 This test method covers the determination of the iodine adsorption number of carbon black.
1.1.1 Procedure A is the original procedure for this determination.
1.1.2 Procedure B specifies an increased sample mass of carbon black and volume of iodine solution (the ratio is the same as in Procedure A) which results in a simplified formula for the calculation of the iodine number.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The iodine adsorption number of carbon black has been shown to decrease with sample aging. Standard values for current SRB's may be obtained from the Subcommittee Chairman of D24.61.
1.4 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.
