Refractory products - Determination of resistance to carbon monoxide (ISO 12676:2000)

This International Standard specifies a method for determining the comparative resistance of refractory materials to
carbon monoxide disintegration.
The test is intended to be more severe than conditions encountered in service in order to enable probable behaviour
of refractory materials to be assessed in a relatively short time.

Overview

EN ISO 12676:2003 is a European and International Standard specifying a method to determine the resistance of refractory products to carbon monoxide (CO) disintegration. Published by CEN based on ISO 12676:2000, this standard provides a rigorous testing procedure to assess how refractory materials behave under severe carbon monoxide exposure. The method is designed to exceed typical service conditions, enabling a rapid and reliable evaluation of material performance against CO-induced damage.

This standard is essential for manufacturers, quality control laboratories, and engineers working with refractory materials used in high-temperature industrial environments where exposure to carbon monoxide is a concern.

Key Topics

  • Scope
    The standard defines testing methods for comparing the resistance of refractory materials to carbon monoxide disintegration, which involves breakdown caused by the deposition of carbon from CO dissociation.

  • Test Principle
    Testpieces of refractory materials are exposed to a controlled atmosphere containing carbon monoxide at a specified temperature and duration under strictly regulated conditions to simulate and accelerate potential disintegration.

  • Apparatus Requirements
    Includes a furnace, gas-tight reaction chamber, temperature controller, gas supply system, and analysis tools to maintain and monitor a CO-rich environment and temperature within precise limits.

  • Testpieces Preparation
    Refractory samples must be prepared as rectangular or square prisms, with specified dimensions and treatments (fired or unfired), ensuring reproducibility and reliability in results.

  • Procedure
    The test cycle involves heating in nitrogen, switching to a controlled CO atmosphere, maintaining test conditions, then flushing with nitrogen and cooling. Continuous monitoring of gas composition and temperature is critical.

  • Assessment of Results
    Post-test evaluation classifies testpieces based on visual and structural conditions: unaffected, surface damage, cracked, or disrupted, providing a clear benchmark of CO resistance.

  • Reporting
    Detailed documentation is required on test conditions, materials, timings, flow rates, outcomes, and observations to ensure traceability and confidence in results.

Applications

EN ISO 12676:2003 is widely applied in the metallurgy, cement, glass, and ceramics industries where refractory linings and components face carbon monoxide atmospheres during high-temperature processes. Key applications include:

  • Quality Control
    Manufacturers test refractory bricks, castables, and shapes to ensure compliance with performance specifications before market release.

  • Material Development
    Research teams use this standard to develop more CO-resistant refractory formulations, enhancing durability and lifespan.

  • Predictive Maintenance
    Facility operators assess the probable degradation rate of installed refractory materials for better maintenance planning and replacement schedules.

  • Safety and Compliance
    Regulatory compliance surrounding toxic CO exposure and refractory performance safety is supported through adherence to this testing protocol.

Related Standards

To complement EN ISO 12676:2003, consider the following related standards which provide additional frameworks for refractory product testing and sampling:

  • ISO 5022:1979 – Shaped refractory products: sampling and acceptance testing
  • ISO 8656-1:1988 – Refractory products: sampling of raw materials and unshaped products – Part 1: Sampling scheme
  • ISO/TC 33 – Technical Committee overseeing refractory material standards
  • Additional ISO and CEN standards covering chemical resistance, thermal shock resistance, and mechanical testing of refractory materials

Adopting EN ISO 12676:2003 allows industries to reliably benchmark the resistance of refractory products to carbon monoxide, ensuring safer, more durable, and more efficient high-temperature operations in CO-rich environments.
