Overview
ISO 11713:2000 specifies the standardized method for determining the electrical resistivity of carbonaceous materials used in aluminium production-specifically cathode blocks and baked anodes-at ambient temperature. This international standard ensures consistent and reliable measurement practices critical to quality control and optimization in aluminium smelting processes. The method involves passing a constant direct current through a prepared sample and measuring the voltage drop to calculate the resistivity, critical for evaluating the performance and durability of carbon materials in industrial applications.
Key Topics
- Scope: Applies to cathode blocks and baked anodes used in aluminium production.
- Sampling: Samples must be prepared according to ISO 8007-1 (cathode blocks) and ISO 8007-2 (prebaked anodes) ensuring representative cylindrical or cuboid specimens, maintaining minimum size requirements for accurate measurement.
- Measurement Principle: Uses direct current supplied through the sample, with voltage sensors measuring the drop, enabling calculation of electrical resistivity at ambient temperature.
- Apparatus Requirements: Includes diamond-tipped drills for sample preparation, precise ammeters, potentiometers or digital voltmeters with IEC 0.5% accuracy, and sample clamping devices with defined sensor and contactor specifications to ensure consistent contact force and measurement accuracy.
- Procedure: Emphasizes controlled sample drying, precise measurement of sample dimensions and sensor positioning, application of 50 N contact force, and rotating the specimen to measure multiple sides or radii for averaging.
- Calculation: Resistivity (µΩ·m) is calculated with a formula involving measured voltage, current, sample cross-sectional area, and length between voltage sensors. Results are rounded based on value magnitude for clarity.
- Precision and Repeatability: Established repeatability of 1.2 µΩ·m and reproducibility of 1.5 µΩ·m support reliable quality assurance.
- Reporting: Test reports must include sample identification, reference to ISO 11713, detailed results with units, any anomalies, and deviations from the standard procedures.
Applications
ISO 11713:2000 plays a vital role in the aluminium industry by:
- Ensuring consistent quality assessment of carbonaceous cathode blocks and anodes critical to electrochemical performance.
- Supporting material selection and process optimization by providing reliable resistivity data essential for minimizing energy losses and improving electrode lifespan.
- Facilitating comparative testing and adherence to international best practices for aluminium production facilities worldwide.
- Enhancing maintenance and troubleshooting by monitoring changes in resistivity that may indicate material degradation or structural issues.
This standard benefits engineers, quality control specialists, and researchers working within aluminium smelting plants and carbon material manufacturing, promoting process efficiency, safety, and sustainability.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical com-
mittees. Each member body interested in a subject for which a technical committee has been established has the
right to be represented on that committee. International organizations, governmental and non-governmental, in liai-
son with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 11713 was prepared by Technical Committee ISO/TC 47, Chemistry, Subcommittee
SC 7, Aluminium oxide, cryolite, aluminium fluoride, sodium fluoride, carbonaceous products for the aluminium in-
dustry.
