10、1 Introduction The fines content of pelletized carbon blacks, as measured in accordance with ISO1435:1988 Rubber compounding ingredients Carbon black (pelletized) Determination of fines content, encompasses not only the fines but also any micro-pellets having a diameter of less that1254m which may b
11、e present. Consequently, ISO1435 is not specific for the determination of the dust content. Pelletized carbon blacks may contain a considerable proportion of micro-pellets. WARNING Persons using this International Standard should be familiar with nomal laboratory practice. This standard does not pur
12、port to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. 1 Scope This International Standard specifies a method for determin
13、ing the dust content of pelletized carbon blacks for use in the industry. This method permits a differentiation to be made between micro-pellets and dust, and is applicable to all pelletized rubber-grade carbon blacks, more particularly to those pellitized by the dry process which frequently have sm
14、aller pellet sizes than their wet-pelletized counterparts. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are s
15、ubject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 383:1976,

ISO 1126:1992, Rubber compounding ingredients Carbon black Determination of loss on heating. 3 Principle A test portion of carbon black is fluidized on
17、 a sintered-glass filter by means of a gas flow. Dust is carried with the gas flow, is separated from the gas in a cyclone, and is finally weighed. 4 Significance and use The dust content of a carbon black is related to the ability of the product to flow freely and, to a certain extent, its dispersi
18、on characteristics. However, in view of the many other variables influencing dispersion and handling, the significance of the dust content must be determined by the user. The dust content can be a relevant parameter in the context of the working-place environment. 5 Apparatus 5.1 Dust-separation equ
