1.1These test methods cover the determination of the heating loss of carbon black at 125°C. This heating loss consists primarily of moisture, but other volatile materials may also be lost. These test methods are not applicable to treated carbon blacks that contain added volatile materials, if moisture loss is to be measured.

1.2These test methods may also be used for the determination of the heating loss of recovered carbon fillers (rCF/rCB) at 125°C. However, these materials were not included in the precision studies and therefore, the precision statements contained in this standard may not be valid for these materials.

1.3The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4This 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.
