Overview

ISO 21626-2:2020 is an international standard published by the International Organization for Standardization (ISO) that specifies the requirements and test methods for bamboo charcoal used in fuel applications. This standard addresses both raw and moulded bamboo charcoal products intended for industrial and domestic energy use. Bamboo charcoal is recognized for its environmental benefits, offering a cleaner-burning alternative to traditional coal fuels due to its low sulfur and nitrogen content. ISO 21626-2:2020 supports the sustainable development of bamboo charcoal as a renewable fuel source and promotes harmonized quality benchmarks for international trade.

Key Topics

  • Scope and Definitions: The standard covers raw and briquetted bamboo charcoal designed for fuel use. Key terms include moisture content, ash content, fixed carbon, and calorific value, which define fuel quality metrics.

  • Quality Requirements: The standard sets specific physical and chemical criteria for bamboo charcoal based on grading levels:

    • Moisture content: Maximum levels range between 9% and 12%.
    • Ash content: Limits vary from 4.5% up to 10.5%.
    • Fixed carbon: Minimum content from 65% to 85%.
    • Calorific value: Minimum energy output ranges from 17 MJ/kg to 29 MJ/kg.
  • Test Methods: Analytical procedures conform to established ISO methods for:

    • Visual inspection
    • Moisture determination (ISO 18134-3)
    • Ash content measurement (ISO 18122)
    • Volatile matter and fixed carbon calculation (ISO 18123)
    • Calorific value assessment (ISO 18125)
  • Sampling and Inspection: The document describes random sampling techniques and sensory evaluations to ensure consistency in product quality.

  • Packaging and Labelling: Guidelines mandate clear marking of manufacturer information, production batch, net mass, product grade, and usage instructions to inform consumers and facilitate traceability.

  • Storage and Transport: Proper handling conditions are outlined to maintain fuel integrity, emphasizing protection from moisture, sunlight, and physical damage.

Applications

ISO 21626-2:2020 facilitates the production and supply of high-quality bamboo charcoal for fuel across multiple sectors, including:

  • Domestic Heating and Cooking: Bamboo charcoal briquettes are widely used in residential energy solutions, offering a cleaner, renewable fuel option.

  • Industrial Energy Use: Industries relying on charcoal fuels can adopt standardized bamboo charcoal, benefiting from predictable combustion efficiency and environmental compliance.

  • Sustainable Energy Production: Bamboo charcoal serves as a substitute for traditional charcoal and fossil fuels, supporting forest conservation and reduced emissions.

  • International Trade: Compliance with ISO 21626-2 ensures that bamboo charcoal products meet global quality standards, encouraging market expansion and consumer confidence.

Related Standards

ISO 21626-2:2020 references several related ISO standards that complement its framework for solid biofuels:

  • ISO 18122: Determination of ash content in solid biofuels.
  • ISO 18123: Determination of volatile matter in solid biofuels.
  • ISO 18134-3: Moisture content determination methods.
  • ISO 18125: Test methods for calorific value of solid biofuels.
  • ISO 18135: Sampling methods for solid biofuels.
  • ISO 16559: Terminology and definitions related to solid biofuels.

These interconnected standards establish a comprehensive system for evaluating fuel properties vital to bamboo charcoal applications.
