ISO 17072 Heavy Metal Release from Plastics Laboratory Testing Service Provided by Eurolab

Introduction

Heavy metal release from plastics is a significant concern for industries that use plastic materials in their products or processes. The release of heavy metals such as lead, cadmium, and chromium can have adverse effects on human health and the environment. As a result, regulatory bodies have implemented standards to ensure that plastic materials meet specific requirements for heavy metal release. Eurolab offers a comprehensive laboratory testing service to determine the level of heavy metal release from plastics, ensuring compliance with international and national standards.

Overview of Relevant Standards

The ISO 17072 standard is an internationally recognized method for determining the release of heavy metals from plastics. This standard is widely adopted by regulatory bodies around the world, including the European Union, the United States, Canada, and Australia.

  • ISO 17072:2019: Heavy metals - Release from plastics - Test method (Edition 1)

    • Scope: This document specifies a test method for determining the release of heavy metals from plastics.

    Normative references: ISO 17252-2, ISO 17252-3, and other relevant standards

  • ASTM D5438-18: Standard Test Method for Determination of Heavy Metals in Plastics (Withdrawn)

    • Scope: This standard specifies a test method for determining the release of heavy metals from plastics.

    Normative references: ASTM D6400, ASTM D6951, and other relevant standards

  • EN 14402-1:2018: Heavy metals - Determination in water and solids (plastics) by atomic absorption spectroscopy (AAS)

    • Scope: This standard specifies a test method for determining the release of heavy metals from plastics.

    Normative references: EN 13907, ISO 17252-2, and other relevant standards

    Legal and Regulatory Framework

    The regulation of heavy metal release from plastics is governed by various international and national laws. Some notable regulations include:

  • REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals) Regulation: This European Union regulation governs the use of chemicals in products, including plastics.

  • RoHS (Restrictions on Hazardous Substances) Directive: This European Union directive restricts the use of hazardous substances in electrical and electronic equipment.

  • California Proposition 65: This California state law requires businesses to inform consumers about potential chemical exposure.

    • Standard Development Organizations

    The development and maintenance of standards for heavy metal release from plastics involve collaboration between various organizations, including:

  • ISO (International Organization for Standardization): ISO is an independent, non-governmental organization that develops and publishes international standards.

  • ASTM International: ASTM International is a standards-developing organization that creates and publishes technical standards for materials, products, systems, and services.

  • CEN (European Committee for Standardization): CEN is a European standards-developing organization that creates and publishes technical standards for Europe.

    • Standard Evolution and Updates

    Standards evolve over time to reflect changes in technology, regulation, or industry practices. The development of new standards or revisions to existing ones involves collaboration between stakeholders, including manufacturers, regulators, and users.

    Overview of Test Methodology

    The test method for determining heavy metal release from plastics involves several steps:

    1. Sample Preparation: A representative sample of the plastic material is prepared according to the standard.

    2. Testing Equipment and Instruments: The testing equipment and instruments used include atomic absorption spectroscopy (AAS), inductively coupled plasma mass spectrometry (ICP-MS), or other suitable methods.

    3. Testing Environment Requirements: The testing environment must be controlled for temperature, humidity, pressure, and other factors that may affect the test results.

    Step-by-Step Explanation of Test Methodology

    The following is a detailed step-by-step explanation of the test methodology:

    1. Sample Preparation

    A representative sample of the plastic material is prepared according to the standard.

    The sample is cut into smaller pieces and weighed accurately.

    2. Testing Equipment and Instruments

    The testing equipment and instruments used include atomic absorption spectroscopy (AAS), inductively coupled plasma mass spectrometry (ICP-MS), or other suitable methods.

    The AAS instrument consists of a hollow cathode lamp, a monochrometer, and a detector.

    3. Testing Environment Requirements

    The testing environment must be controlled for temperature, humidity, pressure, and other factors that may affect the test results.

    The testing area should be well-ventilated to prevent contamination.

    Measurement and Analysis Methods

    The measurement and analysis methods used in determining heavy metal release from plastics include:

  • Atomic Absorption Spectroscopy (AAS): This method involves measuring the absorption of light by atoms at specific wavelengths.

  • Inductively Coupled Plasma Mass Spectrometry (ICP-MS): This method involves measuring the mass-to-charge ratio of ions in a plasma.

    • Reporting and Interpretation of Results

    The reporting and interpretation of results involve:

    1. Data Analysis: The data obtained from the testing equipment is analyzed to determine the concentration of heavy metals.

    2. Result Calculation: The result calculation involves multiplying the concentration by the sample weight and then dividing by the number of test samples.

    3. Reporting: The final report includes a summary of the results, including the concentration of heavy metals and any deviations from the standard.

    Conclusion

    Heavy metal release from plastics is a significant concern for industries that use plastic materials in their products or processes. Regulatory bodies have implemented standards to ensure that plastic materials meet specific requirements for heavy metal release. Eurolab offers a comprehensive laboratory testing service to determine the level of heavy metal release from plastics, ensuring compliance with international and national standards. This document provides an overview of the standard-related information, test conditions, and methodology involved in determining heavy metal release from plastics.
