Revision of D1510-24 Standard Test Method for Carbon Black—Iodine Adsorption Number


Revision of tolerance limits for Iodine and Thiosulfate solution: The current tolerance limits of the solutions are too tight, and they do not reflect consistency that is provided by solution vendors. It was shown that much broader tolerance limits are acceptable and provide acceptable results when the actual solution concentration is taken into consideration in the equation to calculate the Iodine Adsorption Number.
