Full title and description

ISO 1014-2:2025 — Coke — Part 2: Determination of true relative density. This International Standard specifies a laboratory method for determining the true relative density of coke (expressed relative to water), including guidance on sample preparation, displacement liquids and measurement reporting.

Abstract

This part of ISO 1014 provides a standardized procedure to determine the true relative density of coke. It defines required sample conditioning, displacement liquid considerations, apparatus and procedural steps to obtain the true relative density value for coke samples. The document is concise (5 pages) and intended to complement the other parts of the ISO 1014 series that cover related density and porosity measurements.

Scope

ISO 1014-2:2025 specifies the method for determining the true relative density of coke in relation to water. The standard covers the measurement principle using displacement, requirements for sample size and preparation (including references to mechanical and manual sampling procedures), selection and effect of displacement liquids, apparatus and calibration, measurement steps and how to report results. It is intended for crushed coke samples prepared to a specified particle size range as described in the standard and for use in laboratory testing and quality control.

Key topics and requirements

• Definition of "true relative density" and distinction between true and apparent relative density.
• Requirements for sample preparation and particle size prior to measurement.
• Selection and notes on displacement liquids; statement that true relative density value varies with displacement liquid used.
• Apparatus and calibration procedures for displacement/density measurement (volumetric and balance requirements).
• Step-by-step test procedure, including filling, displacement, temperature control and repeat measurements.
• Expression of results, uncertainty considerations and reporting format.
• References to related sampling standards (e.g., mechanical and manual sampling standards) for upstream sample handling.

Typical use and users

ISO 1014-2:2025 is used by industrial testing laboratories, coke producers, metallurgical plants (steelworks), quality control departments, research institutions and regulatory bodies involved with solid fuels and coke testing. Typical applications include routine quality control of coke batches, specification compliance testing, product development and research where accurate material density data are needed for process calculations and performance assessments.
