Standard Test Method for Carbon Black—Sieve Residue

SCOPE
1.1 This test method describes 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.

9.3 After the water pressure has been regulated, attach the
sieve holder with a 50 mm (2 in.) diameter sieve to the funnel
and allow the water to run through it for 3 min. Stop the water
flow by closing valves A and C. Examine the sieve for
particles; if none are observed, the apparatus is ready for use.
