Full title and description

ASTM D1514-23 — Standard Test Method for Carbon Black—Sieve Residue. This test method describes the procedure to determine the water-wash sieve residue in regular (untreated) carbon blacks, including required apparatus, sample preparation, testing steps, calculation of residue, and reporting conventions. It is intended primarily for quality control and specification of carbon blacks used in rubber and related polymer applications.

Abstract

ASTM D1514-23 specifies a water-wash sieving procedure to quantify non-carbon (sieve) residue in carbon black samples. The method emphasizes its applicability to regular untreated carbon blacks (not oil-treated materials), defines equipment and sieving requirements, and explains how results are calculated and reported for use in production quality control and purchaser-supplier agreements.

Scope

This test method covers determination of the water-wash sieve residue in regular untreated carbon blacks. It specifically notes that it may not be applicable to oil-treated carbon blacks because oil treatment can prevent proper wetting by water. The standard states SI units as the primary units and includes safety/health practice reminders for users.

Key topics and requirements

• Purpose and significance: quantifies sieve residue that can affect surface appearance of molded or extruded products.
• Applicability: regular untreated carbon blacks; not generally for oil-treated blacks.
• Apparatus: sieves meeting Spec. E11 (phosphor bronze or stainless steel options), appropriate filtering/sieving assembly, balances (0.01 g and analytical 0.1 mg sensitivity), and regulated convection oven.
• Sample preparation: water wash of a weighed sample, filtration/sieving, drying, and weighing of retained residue.
• Calculation and reporting: residue expressed as mass or mass percent of original sample; report method, sieve type/mesh, and any deviations or agreement between purchaser and supplier.
• Limitations: method performance may be affected by oil treatments or other surface treatments that change wetting behavior.
• References and cross-references: references to sieve specification (E11) and related ASTM practices and guides for sampling, precision, and test validation.

Typical use and users

Used by carbon black producers, rubber and polymer compounders, QC laboratories, materials testing labs, purchasing/specification engineers, and standards/quality personnel to confirm levels of non-carbon residue and ensure product conformance with purchase specifications or internal quality limits.

Related standards

ASTM D1514-23 was developed under Committee D24 (Subcommittee D24.31) and replaces earlier editions (for example D1514-15(2020)). The method cross-references sieve specification E11 and commonly-used D24 series standards and practices (sampling practices D1799 and D1900, validation and precision guides such as D4821, and other carbon black test methods such as oil-absorption methods like D2414). Users commonly consult these related documents when establishing sampling, precision, and interlaboratory comparability.

FAQ

Q: What is this standard?

A: ASTM D1514-23 is the Standard Test Method for Carbon Black—Sieve Residue, a short procedural standard that defines how to determine water-wash sieve residue in regular untreated carbon blacks.

Q: What does it cover?

A: It covers the method for washing carbon black samples with water, sieving/filtration of the wash, drying and weighing of retained residue, calculation of residue values, and reporting — including equipment and procedural notes and limitations (not generally applicable to oil-treated blacks).

Q: Who typically uses it?

A: Carbon black manufacturers, rubber and polymer compounders, materials testing labs, and procurement/quality engineers use it for specification conformance and incoming/outgoing quality checks.

Q: Is it current or superseded?

A: Current — the D1514-23 edition (published 1 April 2023) is the active edition and supersedes earlier editions such as D1514-15(2020).

Q: Is it part of a series?

A: It is part of ASTM Committee D24’s body of carbon black standards and is commonly used alongside other D24 test methods and practices (sampling, absorptive properties, oil absorption, precision/validation guides, etc.).

Q: What are the key keywords?

A: Carbon black, sieve residue, water wash, E11 sieve, quality control, ASTM D1514-23.
