ASTM D1514-23

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D1514 − 15 (Reapproved 2020) D1514 − 23
Standard Test Method for
Carbon Black—Sieve Residue
This standard is issued under the fixed designation D1514; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. 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, health, and environmental practices and determine the applicability of
regulatory limitations prior to use. For specific precautionary statements, see Section 6.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Summary of Test Method
3.1 A sample of carbon black is washed with water through a wire-mesh screen of a specified size until all that remains is a
non-carbon black residue. This residue is dried, weighed, and the amount of residue is expressed as mg/kg (ppm) of the original
sample.
4. Significance and Use
4.1 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.
This test method is under the jurisdiction of ASTM Committee D24 on Carbon Black and is the direct responsibility of Subcommittee D24.31 on Non-Carbon Black
Components of Carbon Black.

5.5 Sieves, of either phosphor bronze or stainless steel. The sieve shall be in accordance with Specification E11. The sieve to be
used shall be agreed upon between the purchaser and the seller.
5.6 Weighing Dishes.
6. Precautions
6.1 Keep the apparatus clean at all times to prevent contamination.
6.2 Examine the sieves each time they are used to make sure that no cracks or holes have developed.
6.3 Examine the strainer periodically to ascertain that the filter screen is in good condition.
NOTE 1—Industrial/O.E.M. filter and pleated polyester fabric reusable cartridges have been found to be a satisfactory strainer.
NOTE 2—Corrosion-free piping must be used.

7. Sampling
7.1 Samples shall be taken in accordance with Practice D1799 or Practice D1900.
8. Calculation
8.1 Calculate the sieve residue to the nearest mg/kg (ppm) as follows:
R 5 W/S ×10 (1)
~ !
where:
R = sieve residue, mg/kg (ppm),
W = mass of sieve residue, g, and
S = mass of sample, g.
9. Procedure
9.1 Prior to making a test, clean the strainer by opening valves A and B and closing valve C as shown in Fig. 1. Allow the strainer
to wash for 2 min.
9.2 Close valve B and open valve C. With valves A and C completely open, regulate the water pressure by means of a reducing
valve. The recommended water pressure is 207 6 34 kPa (30 6 5 lbf/in. ).
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.
9.4 Weigh 100.0 g of the carbon black on the balance.
9.5 Attach the proper sieve to the funnel and start the water flow by opening valves A and C.
9.6 Add the carbon black slowly to the funnel to prevent plugging of the sieve.
NOTE 1—If desired it is 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 comin
