Full title and description
St ASTM D8143-24e1 — Standard Test Method for Determination of the EU‑11 List of PAH Compounds in Carbon Black. This test method specifies a Soxhlet extraction with toluene followed by analysis of the extract using gas chromatography with mass spectrometry (GC/MS) to provide qualitative and quantitative determination of the EU‑11 polycyclic aromatic hydrocarbons (PAHs) on carbon black. This edition includes amendments and changes issued 12/23/2024.
Abstract
This standard describes a laboratory procedure for extracting and measuring the EU‑11 PAH compounds present on carbon black materials. It is written in SI units, includes safety and regulatory notes, and clarifies that it is not intended for demonstrating compliance with certain FDA indirect food‑contact regulations. The method yields individual concentrations for each PAH in the EU‑11 list using Soxhlet extraction (toluene) and GC/MS analysis.
General information
- Status: Current (active test method edition).
- Publication date: Edition published May 1, 2024; includes amendments/changes dated December 23, 2024.
- Publisher: ASTM International.
- ICS / categories: Occupational safety / industrial hygiene and aromatic hydrocarbons (examples cited: 13.100; 71.080.15).
- Edition / version: D8143‑24e1 (2024, E1 edition including the 12/23/2024 changes).
- Number of pages: 9 pages.
Scope
The standard covers the qualitative and quantitative determination of the EU‑11 list of PAH compounds on carbon black. It specifies sample extraction by Soxhlet with toluene and subsequent extract analysis using GC/MS. The procedure is intended for carbon black material testing and is not intended to establish compliance with FDA 21 CFR 178.3297 for indirect food contact applications. The standard uses SI units throughout and highlights user responsibility for safety and regulatory applicability.
Key topics and requirements
- Target analytes: EU‑11 list of polycyclic aromatic hydrocarbons (PAHs) defined in the standard.
- Extraction method: Soxhlet extraction using toluene as solvent.
- Analytical technique: Gas chromatography with mass spectrometry (GC/MS) for qualitative and quantitative determination.
- Reporting: Individual concentrations for each PAH in SI units; procedures for blank, calibration and recovery are addressed by the method.
- Regulatory note: Method explicitly not intended for demonstrating compliance with certain FDA indirect food‑contact regulations; references EU chemical classification considerations.
- Precision and bias: a precision/bias statement was identified as a topic for a subsequent work item (revision activity).
Typical use and users
Primary users are analytical and quality laboratories in the carbon black, rubber and pigment industries, regulatory testing laboratories, product compliance specialists, and research groups concerned with PAH content and occupational/environmental safety. The method is used for material characterization, supplier verification, and regulatory or internal safety screening where EU‑list PAH quantification on carbon black is required.
Related standards
Related documents include other ASTM methods for carbon black characterization and PAH analysis, and relevant regulatory documents referenced in the method (for example, EU chemical classification and labelling references cited in the standard). The standard also cross‑references regulatory and test methods where applicability differs (for example, FDA food‑contact rules are noted but not covered). Users should consult the ASTM Book of Standards and subcommittee D24 publications for additional, closely related test methods.

FAQ
Q: What is this standard?
A: ASTM D8143‑24e1 is a test method that defines how to extract and measure the EU‑11 list of PAH compounds from carbon black using Soxhlet extraction (toluene) and GC/MS analysis.
Q: What does it cover?
A: It covers qualitative and quantitative determination of the EU‑11 PAHs on carbon black, details the extraction and analytical approach, unit conventions (SI), and includes safety and regulatory notes. It is not intended for demonstrating compliance with FDA indirect food‑contact requirements.
Q: Who typically uses it?
A: Analytical and QA/QC laboratories in industry and regulatory settings that test carbon black, as well as product developers and safety/regulatory personnel concerned with PAH content.
Q: Is it current or superseded?
A: The D8143‑24e1 edition is listed as current/active; the edition was published in 2024 (with changes dated 12/23/2024). A subsequent ASTM work item to add a precision and bias statement has been initiated (work item WK95416).
Q: Is it part of a series?
