7、.Summary of Test Method3.1 A sample of carbon black is washed with water througha wire-mesh screen of a specified size until all that remains isa non-carbon black residue.This residue is dried,weighed,andthe amount of residue is expressed as mg/kg(ppm)of theoriginal sample.4.Significance and Use4.1
8、The quantity of sieve residue of carbon black is impor-tant in some molded or extruded products as it may relate to thesurface appearance of those products.The maximum residue ineach application is normally determined and agreed to betweenthe user and the producer.5.Apparatus5.1 Sieve and Filtering
