ISO 10237-1997 PDF

Full title and description

ISO 10237:1997 — Carbonaceous materials for use in the production of aluminium — Calcined coke — Determination of residual-hydrogen content. This international standard specifies a laboratory method for determining the residual (remaining) hydrogen in calcined coke used for aluminium anode manufacture; available in English and French.

Abstract

ISO 10237:1997 defines a combustion/absorption test procedure to quantify residual hydrogen in calcined coke (the criterion for degree of calcination). The method is intended for materials with residual-hydrogen below about 1 % (m/m) and yields repeatable, laboratory-grade results that support quality control of anode feedstocks.

General information

• Status: Published (confirmed by ISO at latest systematic review).
• Publication date: 22 May 1997.
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 71.100.10 — Materials for aluminium production.
• Edition / version: Edition 1 (1997).
• Number of pages: 6 pages (short technical method).

Scope

This standard applies to calcined coke used in carbonaceous materials for the production of aluminium and gives a laboratory procedure for determining residual hydrogen content. The method is applicable only to products with residual-hydrogen content below about 1 % (m/m). Normative sampling references (e.g., ISO 6375) are cited.

Key topics and requirements

• Measurement principle: complete combustion of a prepared test portion in an oxygen stream; generated water is collected/absorbed and quantified to calculate hydrogen content.
• Applicability limit: designed for calcined coke with residual hydrogen < 1 % (m/m).
• Sample preparation: crushing/size reduction and drying are specified to ensure representative, repeatable results.
• Apparatus and reagents: combustion furnace, oxygen supply, absorption/collection units and precision balance; performance accuracy and repeatability criteria are provided.
• Referenced normative documents: includes references to related sampling and test standards (for example ISO 6375 and ISO 4793 as cited in adopting/related national texts).

Typical use and users

Primary users are metallurgical laboratories, quality-control teams at aluminium smelters and suppliers of calcined coke and other carbonaceous materials. Typical uses include production control of calcination processes, incoming material inspection for anode manufacture, and verification for contract/specification compliance.

Related standards

Closely related standards address sampling and other properties of coke and carbonaceous materials (examples referenced in related catalogues/adoptions include ISO 6375, ISO 4793 and later/adopted national versions such as GOST R ISO 10237-2016). Other ISO standards on calcined coke (e.g., methods for water content or coking value) are often used in conjunction with ISO 10237.
