Full title and description

ISO 1014-1:2025 — Coke — Part 1: Determination of apparent relative density. This part specifies the laboratory method to determine the apparent relative density of coke (the ratio of the mass of a volume of dry coke to the mass of an equal volume of water), intended for quality control and material characterisation in the coke and metallurgical industries.

Abstract

This document provides a standardised procedure for measuring the apparent relative density of coke, covering sample conditioning, apparatus, test procedure, calculations and expression of results. It is one part of a set that replaces the earlier consolidated ISO 1014:2021.

General information

• Status: Published.
• Publication date: July 2025 (published July 2025; listed on ISO as 2025-07).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 75.160.10 (Coke).
• Edition / version: Edition 1, 2025.
• Number of pages: 6 pages (official ISO listing).

Scope

Defines the laboratory method for determining the apparent relative density of coke by comparing the mass of a defined volume of dry coke with the mass of an equal volume of water. The standard covers sample preparation, required apparatus, step-by-step test procedure, calculations and reporting of results; it is intended for use where apparent relative density is a required material property for quality control, specification or research.

Key topics and requirements

• Definition of apparent relative density and its relevance to coke quality.
• Sampling and sample preparation (drying, sieving/particle-size considerations where applicable).
• Required apparatus (volumetric vessels, balances, temperature control) and calibration checks.
• Step-by-step measurement procedure and calculation method for apparent relative density.
• Expression and rounding of results, and typical reporting elements (test conditions, sample mass, temperature).
• Notes on uncertainty, repeatability and potential interferences (moisture, fines, trapped air).
• Cross-references to companion parts for true relative density and porosity.

Typical use and users

Used by coke producers, steelmakers, independent testing laboratories, research institutions and quality assurance teams to characterise coke physical properties and ensure compliance with material specifications. It supports process control, incoming material inspection and laboratory intercomparisons.

Related standards

ISO 1014 is now published as a multipart standard. Relevant related documents include ISO 1014-2:2025 (Determination of true relative density) and other parts covering porosity and related measurements; the 2025 parts replace and update the withdrawn ISO 1014:2021. National adoptions (for example BS ISO 1014-1:2025) may exist with country-specific metadata.

FAQ

Q: What is this standard?

A: ISO 1014-1:2025 is the first part of the ISO 1014 series, titled "Coke — Part 1: Determination of apparent relative density", which specifies a laboratory method to measure apparent relative density of coke.

Q: What does it cover?

A: It covers sample conditioning, required equipment, the stepwise test method, calculation of apparent relative density (mass of a defined coke volume compared to an equal volume of water), and reporting of results; it is focused specifically on apparent relative density rather than true density or porosity.

Q: Who typically uses it?

A: Coke manufacturers, steelworks, commercial testing laboratories, QA/QC staff and researchers who need a standardised measurement for material specification and process control.

Q: Is it current or superseded?

A: ISO 1014-1:2025 is published and current (July 2025). It is part of a restructured multipart replacement of the withdrawn ISO 1014:2021.

Q: Is it part of a series?

A: Yes — ISO split the former consolidated ISO 1014 into parts in 2025; Part 1 addresses apparent relative density, and Part 2 addresses true relative density (and other parts cover related properties). See ISO 1014-2:2025 for the companion method for true relative density.

Q: What are the key keywords?

A: Coke, apparent relative density, density measurement, ISO 1014-1, laboratory procedure, metallurgical coke, sample preparation, test method.
