Full title and description

ISO 1014-3:2025 — Coke — Part 3: Determination of porosity. This International Standard specifies a laboratory method for determining the porosity of coke used in industrial and metallurgical processes.

Abstract

This document defines the procedure to measure and calculate the porosity of coke samples. It is intended to provide a concise, reproducible test method to support quality control, specification compliance and comparative assessments of coke porosity.

General information

• Status: Published (current).
• Publication date: July 2025 (national bodies list an effective date of 21 July 2025).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 75.160.10 (Solid fuels).
• Edition / version: Edition 1 (2025).
• Number of pages: 2 (as published by ISO).

Scope

This part of ISO 1014 specifies a laboratory method for the determination of the porosity of coke. It replaces the relevant porosity material contained in the earlier consolidated ISO 1014:2021 and is focused specifically on porosity measurement, while other parts in the series cover related density and measurement topics.

Key topics and requirements

• Definition of porosity terms relevant to coke samples (apparent and true porosity distinctions).
• Sample preparation requirements (particle size, drying, conditioning).
• Measurement procedure and apparatus needed to determine porosity.
• Calculation steps to convert measured values into porosity percentage or fraction.
• Reporting format and minimum information to include with results (sample identification, test conditions, any deviations).

Typical use and users

Used by materials testing laboratories, coke producers, steel and metallurgical plants, quality assurance teams, research institutions and standards bodies. Typical uses include product specification verification, incoming material inspection, process control and comparative research on coke quality and performance in industrial furnaces.

Related standards

This part is one of a series revising and replacing the consolidated ISO 1014:2021. Related documents include ISO 1014-1:2025 and ISO 1014-2:2025 (density and related measurements) and the withdrawn ISO 1014:2021 which has been superseded by the 2025-part series. Users may also refer to national test methods and complementary standards on solid-fuel characterization.

FAQ

Q: What is this standard?

A: ISO 1014-3:2025 is an ISO International Standard titled "Coke — Part 3: Determination of porosity" that specifies a laboratory method for measuring coke porosity.

Q: What does it cover?

A: It covers sample preparation, measurement procedure, required apparatus, calculations and reporting for determining the porosity of coke samples. It is focused specifically on porosity rather than the broader density suite.

Q: Who typically uses it?

A: Materials and testing laboratories, coke producers, steelmakers and metallurgical process engineers, QA/QC teams, and researchers working with solid fuels and coke characterization.

Q: Is it current or superseded?

A: It is current (published in July 2025) and replaces the porosity content of the withdrawn ISO 1014:2021 as part of a multipart revision. National catalogues list an effective date of 21 July 2025 for publication.

Q: Is it part of a series?

A: Yes — ISO has issued ISO 1014 as a multipart series in 2025. ISO 1014-1 and ISO 1014-2 accompany Part 3 to cover related density and measurement topics. The multipart structure replaces the single ISO 1014:2021 document.

Q: What are the key keywords?

A: Coke, porosity, solid fuels, sample preparation, density measurement, metallurgical coke, ISO 1014-3.
