Full title and description

ISO 1014:1985 — "Coke — Determination of true relative density, apparent relative density and porosity". This second-edition international standard (September 1985) specifies laboratory methods for measuring the true relative density of finely ground coke, the apparent relative density of bulk coke by water displacement, and the calculation of porosity; Russian-language PDF reproductions and national adoptions exist.

Abstract

The standard defines a pyknometer-based procedure to determine true relative density of coke ground to pass a 212 µm sieve, a displacement method to determine apparent relative density of bulk coke, and the mathematical relation used to calculate porosity from the two density values. The document includes requirements for sample preparation, test liquids and temperature control to achieve specified accuracy.

Scope

ISO 1014:1985 specifies laboratory test methods to (a) determine the true relative density of coke ground to pass a 212 µm sieve using a pyknometer and water as displacement liquid, (b) determine the apparent relative density of bulk coke by water displacement, and (c) calculate porosity from the measured densities. The standard includes sample preparation, required apparatus (pyknometer, thermostatic bath, balance), temperature control guidance and accuracy notes.

Key topics and requirements

• True relative density determination using a pyknometer and air-free distilled water, with specified sample grind size (pass 212 µm).
• Apparent relative density by volume displacement of a bulk coke charge and mass comparison to equal volume of water.
• Calculation of total porosity from true and apparent relative densities.
• Requirements for sample drying (reference to ISO 687 for moisture determination), thermostatic control and balance accuracy (typical accuracy to 0.1 mg noted).
• Notes on choice of displacement liquid and effect on reported "true relative density".

Typical use and users

Used by metallurgical plants, coke producers, laboratory analysts, quality-control and research laboratories working with solid fuels and coke properties, as well as national standards bodies and testing services performing fuel characterization. Laboratories may reference this edition for historical procedures but should consult current ISO publications for the up-to-date methods.

Related standards

Related references include ISO 687 (determination of moisture in coke analysis samples) and later revisions/replacements of ISO 1014 (ISO 1014:2021, and the subsequent ISO 1014-1/2/3 series published in 2025 which reorganize and update the methods). National adoptions and corrigenda (for example ISO 1014:1985/Cor 1:1994) are also relevant.

FAQ

Q: What is this standard?

A: ISO 1014:1985 is an International Organization for Standardization document titled "Coke — Determination of true relative density, apparent relative density and porosity" that specifies laboratory methods for density and porosity measurement of coke.

Q: What does it cover?

A: It covers the pyknometer method for true relative density (for coke ground to pass 212 µm), a water-displacement method for apparent relative density of bulk coke, and the calculation of porosity from those values, plus apparatus, sample preparation and accuracy considerations.

Q: Who typically uses it?

A: Metallurgical and coke-production laboratories, fuel testing and quality-control facilities, research groups studying solid fuels, and standards organizations. Practitioners performing routine or comparative density/porosity testing of coke will use the described procedures.

Q: Is it current or superseded?

A: ISO 1014:1985 has been withdrawn and superseded by later editions; ISO published ISO 1014:2021 and the ISO 1014 series (Parts 1–3) in 2025 that reorganize and update the methods. Users seeking current, authoritative procedures should consult the latest ISO publications.

Q: Is it part of a series?

A: The 1985 document was a standalone second-edition standard; the ISO family for this subject has since been restructured (most recently into a multi-part series published in 2025). See the ISO catalogue for the current part numbers and scopes.

Q: What are the key keywords?

A: Coke, density, true relative density, apparent relative density, porosity, pyknometer, displacement, solid fuels, sample preparation, 212 µm.
