ASTM D1799-20 (2025) PDF

Full title and description

ASTM D1799-20(2025) — Standard Practice for Carbon Black—Sampling Packaged Shipments. Provides standardized procedures for obtaining representative samples of carbon black from packaged shipments (bags, cartons, flexible intermediate bulk containers (FIBC) and other non-bulk packages) to permit determination of average quality and variability of the shipment.

Abstract

This practice defines how to take representative samples from packaged shipments of carbon black for subsequent laboratory testing. It specifies sampling locations and handling to ensure samples accurately reflect the shipment and refers users to the appropriate ASTM test methods for analysis of the sampled material. The standard uses SI units as the primary units and emphasizes user responsibility for safety and regulatory compliance.

Scope

This practice covers sampling procedures for packaged carbon blacks shipped in bags, cartons, flexible intermediate bulk containers (FIBC), or other non-bulk packages. It is intended to produce representative samples used to determine average quality or variability of the shipment; the specific laboratory tests to be performed on the samples are determined separately and are described in the appropriate ASTM test methods for carbon black. The standard notes that SI units are the standard and that users must address safety, health, and environmental practices.

Key topics and requirements

• Procedures for selecting and withdrawing representative samples from individual packages and across a shipment.
• Guidance for sampling different package types: bags, cartons, and flexible intermediate bulk containers (FIBC).
• Instructions on sample size, combining/subsampling, and sample handling to avoid contamination or segregation.
• Reference to applicable ASTM test methods to be used on the sampled material (tests for physical and chemical properties are specified elsewhere).
• Use of SI units as the standard and user responsibility for safety and regulatory compliance when sampling and handling carbon black.

These requirements and topics are summarized from the ASTM practice text.

Typical use and users

Primary users are carbon black producers and consumers, quality control and analytical laboratories, shipping and receiving personnel, and rubber compounding formulators who require representative samples to verify product quality and conformity. Users follow this practice to obtain samples for subsequent ASTM test methods used in specification and acceptance testing.

Related standards

D1799 is used in conjunction with other ASTM methods and practices for testing and evaluating carbon black (examples include various D1xxx series test methods for carbon black physical and chemical evaluation and other D24 committee standards). Related and cross-referenced standards are listed in the ASTM Book of Standards under the D24 committee entries.

FAQ

Q: What is this standard?

A: ASTM D1799-20(2025) is an ASTM practice that specifies how to obtain representative samples of carbon black from packaged shipments (bags, cartons, FIBC and other non-bulk packages) for laboratory testing and quality assessment.

Q: What does it cover?

A: It covers sampling locations and procedures, sample size and handling, and general guidance to ensure samples reflect the shipment. The practice does not prescribe the analytical test methods — those are selected separately and referenced in the relevant ASTM test methods for carbon black.

Q: Who typically uses it?

A: Carbon black manufacturers and purchasers, QC/analytical laboratories, warehouse/shipping staff, and rubber compounding engineers use it to obtain and prepare samples for acceptance testing and quality control.

Q: Is it current or superseded?

A: This document was reapproved and published as D1799-20(2025) (reapproval of the 2020 edition). A subsequent revision appears in ASTM listings as D1799-25 (published December 15, 2025), which supersedes the 2020/2025 reapproval. Users should confirm they are using the edition required by their contract or specification.

Q: Is it part of a series?

A: Yes — D1799 is part of the suite of ASTM standards developed by Committee D24 (Carbon Black) and is commonly used alongside ASTM test methods for carbon black evaluation found in the Book of Standards (Book 09.01 and related sections).

Q: What are the key keywords?

A: carbon black; sampling; packaged shipments; bags; cartons; flexible intermediate bulk containers (FIBC); representative sample; rubber compounding ingredients.
