This International Standard specifies a method for determining 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 pelletized by the dry process which frequently have smaller pellet sizes tha n their wet pelletized counterparts.
