Resumen

ISO 1304:2016 specifies methods for the determination of iodine adsorption number of carbon blacks for use in the rubber industry. Two titration methods are described:

- method A: titration using a burette and starch as indicator;

- method B: potentiometric titration with an automatic titrator.

The iodine adsorption number is related to the surface area of a carbon black and is generally in agreement with the nitrogen surface area. However, it is significantly depressed in the presence of a high content of volatile or solvent-extractable materials; the iodine adsorption number therefore does not always provide a measure of the specific surface area of a carbon black. Ageing of carbon black can also influence the iodine number.

In case of dispute, the preferred method is method B (potentiometric titration).
