Abstract / scope
ISO 1126:2006 specifies methods for determining the loss on heating of carbon black for use in the rubber industry. This loss on heating is due primarily to loss of moisture, but traces of other volatile materials may also be lost.
The methods are not applicable to treated carbon blacks which contain added volatile materials.
The following methods are described:
- method 1: gravity-convection oven method;
- method 2: moisture balance method;
- method 3: infrared irradiation method (rapid method).
