(Test Method)Standard Test Methods for Carbon Black—Heating Loss
Standard Test Methods for Carbon Black—Heating Loss
SIGNIFICANCE AND USE
4.1 In addition to determining the heating loss (primarily moisture content) of carbon black, these drying conditions are used to prepare samples prior to performing other carbon black tests.
4.2 When larger samples are prepared for other tests, use an open vessel of suitable dimensions so that the depth of the black is no more than 10 mm during conditioning.
4.3 Carbon black is hygroscopic. The amount of moisture absorbed is related to the surface area of the black and to the relative humidity, ambient temperature, and time to which the material is exposed.
SCOPE
1.1 These 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.
1.2 These 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.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
