Comprehensive Guide to IEC 62321-23 Determination of Cadmium in Electronic Components Laboratory Testing Service Provided by Eurolab

IEC 62321-23 is a widely recognized international standard for the determination of cadmium in electronic components. This standard is part of the IEC 62321 series, which deals with the measurement of hazardous substances in articles with or without pre-treated layers. The standard is designed to ensure the accuracy and reliability of measurements, while also providing guidance on the sampling and testing procedures.

Legal and Regulatory Framework

The determination of cadmium in electronic components is regulated by various international and national standards. For example:

  • EU RoHS (Restriction of Hazardous Substances) Directive 2015/863: This directive restricts the use of hazardous substances, including cadmium, in electrical and electronic equipment.

  • China RoHS (Restriction of Hazardous Substances) Regulation: This regulation restricts the use of hazardous substances, including cadmium, in electrical and electronic products sold in China.

  • WEEE (Waste Electrical and Electronic Equipment) Directive 2012/19/EU: This directive requires manufacturers to take back waste electrical and electronic equipment, including components containing cadmium.

    • Standard Development Organizations

    IEC 62321-23 is developed by the International Electrotechnical Commission (IEC), which is a global organization that develops and publishes international standards for electrical and electronic products. The IEC works closely with national standard development organizations, such as:

  • DIN (Deutsches Institut für Normung) in Germany

  • AFNOR (Association Française de Normalisation) in France

  • BSRIA (British Standards Institution) in the UK

    • Evolution of Standards

    Standards evolve over time to reflect changes in technology and regulatory requirements. IEC 62321-23 is regularly reviewed and updated to ensure that it remains relevant and effective.

    Standard Numbers and Scope

    The scope of IEC 62321-23 includes:

  • Determination of cadmium in electronic components

  • Sampling and testing procedures

  • Measurement uncertainty

    • The standard provides guidance on the measurement of cadmium in various types of electronic components, including printed circuit boards, connectors, and switches.

    Standard Compliance Requirements

    Compliance with IEC 62321-23 is mandatory for manufacturers that wish to export their products to countries that have adopted the standard. Additionally, many countries require compliance with this standard as part of their national regulations.

    3. Measurement: Determination of cadmium content using a suitable method (e.g. AAS, ICPMS)

    4. Data analysis: Calculation of measurement results

    Sampling and Testing Procedures

    The standard provides guidance on sampling and testing procedures, including:

  • Selection of sample size and type

  • Preparation of samples for analysis

  • Measurement uncertainty estimation

    • Measurement Uncertainty Estimation

    Measurement uncertainty is estimated using a range of methods, including:

  • Calibration and validation procedures

  • Precision-to-tolerance (P/T) ratio

  • Expanded uncertainty (U)

    • Data Analysis

    The measurement results are analyzed to determine the concentration of cadmium present in each sample. The data is then used to calculate the average value and associated measurement uncertainty.

    Test Conditions

    The test conditions for IEC 62321-23 testing include:

  • Sample preparation: Electronic components must be cleaned and prepared according to the standard

  • Measurement: Measurements must be performed using a suitable method (e.g. AAS, ICPMS)

  • Data analysis: Data must be analyzed using established procedures

    • Standard-Related Information Summary

    IEC 62321-23 is an international standard for the determination of cadmium in electronic components. The standard provides guidance on sampling and testing procedures, measurement uncertainty estimation, and data analysis.
