ISO 21268-1 Batch Leaching Test for Hazardous Waste Test
The ISO 21268-1 standard provides a robust framework for the batch leaching test (BLT) method, which is widely used to assess the potential environmental impacts of hazardous waste. This testing protocol evaluates the leachability of heavy metals and other contaminants from solid wastes under controlled conditions. The primary objective is to predict the release behavior of harmful substances into the environment if such materials were to be disposed of improperly.
The batch leaching test follows a standardized procedure that simulates real-world scenarios where hazardous waste may come into contact with water, resulting in potential contamination of soil and groundwater. This method helps regulatory bodies and industry stakeholders ensure compliance with stringent environmental regulations designed to protect public health and the environment.
Our laboratory adheres strictly to ISO 21268-1 guidelines to conduct these tests accurately. We employ advanced analytical techniques such as ICP-AES (Inductively Coupled Plasma Atomic Emission Spectroscopy) for quantifying trace elements, XRF (X-ray Fluorescence) analysis for elemental composition, and other relevant instrumentation. These tools ensure precise measurement of leachate concentrations which are critical in determining the hazardousness of waste materials.
The testing process involves several key steps: sample preparation, conditioning period, extraction, and analysis. Samples must be carefully prepared to represent the actual waste composition accurately. The conditioning phase allows any volatile components or moisture to equilibrate before leaching begins. Extraction typically uses distilled water or other specified solvents depending on the test conditions.
After extracting the leachate, we analyze it for various parameters including pH levels, total dissolved solids (TDS), and specific pollutants like cadmium, chromium, lead, mercury, copper, zinc, silver, nickel, cobalt, arsenic, selenium, beryllium, molybdenum, vanadium, tungsten, fluorides, radionuclides, and other heavy metals. Acceptance criteria are based on national and international standards such as EPA (USA), OSPAR Convention (Europe), and others.
The results of the ISO 21268-1 batch leaching test play a crucial role in guiding decisions about waste management practices. They inform strategies for proper disposal methods, recycling processes, or risk mitigation measures. By providing reliable data on contaminant release potential, this testing ensures compliance with regulatory requirements and supports sustainable resource management.

With state-of-the-art facilities and adherence to global standards, we offer comprehensive services tailored specifically for this type of hazardous waste evaluation.
Applied Standards
The ISO 21268 series has become an important reference in the field of waste management. This particular part (ISO 21268-1) focuses on batch leaching tests, which are essential for understanding how hazardous substances might behave when exposed to water during disposal or landfill operations.
The standard specifies procedures for conducting batch leachate tests according to a specified temperature and time duration. It includes detailed instructions on sample preparation, conditioning periods, extraction methods, and analytical techniques used in measuring contaminants present in the extracted solution.
Compliance with ISO 21268-1 ensures that all parties involved—whether they are manufacturers, regulators, or end users—are working towards consistent quality assurance practices. By following these internationally recognized guidelines, our laboratory maintains high standards of accuracy and reliability throughout every stage of testing.
Industry Applications
The ISO 21268-1 batch leaching test is particularly valuable across multiple sectors where hazardous waste management plays a critical role. In the chemical industry, it helps ensure that products do not pose undue risks during production or transportation phases. Similarly, in construction and demolition projects, this testing ensures that debris from these processes does not contaminate surrounding areas.
For electronics manufacturers, it allows for proper disposal of end-of-life products containing toxic materials like lead, mercury, cadmium, etc., thereby reducing environmental impacts. In healthcare facilities, it aids in managing biohazardous waste safely and effectively.
In research institutions conducting experiments involving hazardous chemicals or radioactive substances, the test ensures that any residual materials are handled responsibly to prevent accidental releases into natural ecosystems.
By leveraging ISO 21268-1 batch leaching tests, industries can demonstrate their commitment to sustainability initiatives while adhering strictly to legal frameworks aimed at protecting public health and environmental integrity.
