Standard Test Method for Carbon Black<char: emdash>Sieve Residue

SIGNIFICANCE AND USE
The quantity of sieve residue of carbon black is important in some molded or extruded products as it may relate to the surface appearance of those products. The maximum residue in each application is normally determined and agreed to between the user and the producer.
SCOPE
1.1 This test method covers the determination of the water wash sieve residue in regular untreated carbon blacks. It may not be applicable to oil-treated carbon blacks because the oil would prevent proper wetting of the black by water.
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.3 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 6.

NOTE 1—If desired, it shall be permissible to disperse the carbon black
in water using a high speed stirring apparatus. It shall also be permissible
to utilize wetting agents to facilitate dispersion. Care must be taken to
ensure that all of the solid material is transferred from the vessel used for
dispersing the black into the funnel of the washing apparatus.
9.7 Use a gentle stream of water from the hose attached to
valve D to wash down any carbon black on the sides of the
funnel.
9.8 Continue washing until the wash water coming through
the sieve is clear.
9.9 Remove the sieve holder and sieve from the funnel and
rub the residue lightly with the finger to disaggregate any hard
carbon black lumps which may not have been thoroughly wet
by the water.
