Comprehensive Guide to ISO 21268 Series Leaching Tests for Waste Testing Services Provided by Eurolab

ISO 21268 Series Leaching Tests for Waste testing is a laboratory test method that evaluates the leachability of waste materials. The standard is part of the International Organization for Standardization (ISO) series and is widely recognized as a benchmark for assessing the environmental impact of waste disposal.

Overview of Relevant Standards

  • ISO 21268-1:2008 - Leaching behaviour of construction materials and solid wastes - Compliance evaluation of leaching tests

  • ISO 21268-2:2010 - Leaching behaviour of construction materials and solid wastes - Test for leaching of granular waste materials in a batch test at a controlled pH (in the presence of an organic phase)

  • EN 12457-1:2003 - Characterization of waste - Leaching tests - Batch test with or without initial extraction

  • ASTM D5232-09 - Standard Practice for In-Place Determination of Moisture Content in Soils and Rock by the Calcium Carbide Method

    • International and National Standards

    The ISO 21268 Series is an international standard, but it has been adopted as a national standard in several countries. For example, in Europe, EN 12457-1:2003 is equivalent to ISO 21268-2:2010.

    Standard Development Organizations

    The development of standards for waste testing is a collaborative effort between various organizations, including:

  • International Organization for Standardization (ISO)

  • European Committee for Standardization (CEN)

  • American Society for Testing and Materials (ASTM)

    • Evolution and Updates of Standards

    Standards are regularly reviewed and updated to reflect changes in technology, regulations, or new research findings. For example, ISO 21268-2:2010 was revised in 2020 to include additional requirements for leaching tests.

    Standard Numbers and Scope

    The following standard numbers and their scope are relevant to ISO 21268 Series Leaching Tests for Waste testing:

  • ISO 21268-1:2008 - Covers the principles of leaching tests, including batch and column tests

  • ISO 21268-2:2010 - Covers the test method for leaching granular waste materials in a batch test at a controlled pH (in the presence of an organic phase)

    • Industry-Specific Standards

    Different industries may have specific standards or guidelines for waste testing. For example:

  • Construction industry: EN 12457-1:2003

  • Mining industry: ASTM D5232-09

    • Compliance Requirements

    Conformance to ISO 21268 Series Leaching Tests for Waste testing is mandatory in several countries, including those in the European Union. Compliance with these standards ensures that waste materials meet environmental and regulatory requirements.

    Why This Specific Test is Needed and Required

    ISO 21268 Series Leaching Tests for Waste testing are essential to assess the leachability of waste materials, which can pose significant environmental risks if not properly managed. These tests evaluate the ability of waste materials to release harmful substances into the environment.

    Business and Technical Reasons for Conducting This Test

  • Regulatory compliance: Many countries have regulations requiring waste generators to conduct leaching tests on their waste materials.

  • Environmental protection: Leaching tests help identify potential environmental hazards associated with waste disposal.

  • Product safety and reliability: Manufacturers of construction materials and solid wastes need to demonstrate that their products meet regulatory requirements.

    • Consequences of Not Performing This Test

    Companies that conduct ISO 21268 Series Leaching Tests for Waste testing can gain a competitive advantage in several ways, including:

  • Demonstrating commitment to environmental protection

  • Ensuring regulatory compliance

  • Enhancing reputation and brand image

    • ISO 21268 Series Leaching Tests for Waste testing involve the following methods:

    1. Batch Test: A batch test involves placing a sample of waste material in contact with an extractant solution under controlled conditions.

    2. Column Test: A column test involves passing a flow of extractant solution through a column filled with waste material.

    Equipment and Materials

    The following equipment and materials are used for ISO 21268 Series Leaching Tests for Waste testing:

  • Extraction vessels

  • pH meters

  • Turbidity meters

  • Sampling devices

    • Testing Procedure

    The testing procedure involves the following steps:

    1. Sample Preparation: The waste material is prepared according to the standard requirements.

    2. Leaching Test: The leaching test is conducted using a batch or column test method.

    3. Analysis: The extracted solution is analyzed for pH, turbidity, and other relevant parameters.

    Results and Interpretation

    The results of ISO 21268 Series Leaching Tests for Waste testing are used to:

  • Evaluate the environmental impact of waste materials

  • Identify potential hazards associated with waste disposal

  • Ensure compliance with regulatory requirements

    • ISO 21268 Series Leaching Tests for Waste testing are essential for assessing the leachability of waste materials.
