What is EN 62321-6:2020?

The International Electrotechnical Commission (IEC) has developed a set of standards known as EN62321, which focuses on the restriction of hazardous substances in electronic and electrical equipment. Among these standards, EN62321-6:2020 specifically addresses the determination of certain restricted substances.

Scope and Purpose

EN62321-6:2020 provides guidelines for the sample preparation and determination of specific substances such as lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr(VI)), polybrominated diphenyl ethers (PBDEs), and polybrominated biphenyls (PBBs).

This standard aims to ensure that electronic and electrical equipment meets the necessary requirements when it comes to hazardous substance control, providing a safer environment and preventing potential health risks associated with the use or disposal of such products.

Sampling and Preparation

In accordance with EN62321-6:2020, samples should be taken from the equipment to analyze the presence and concentration of restricted substances. The standard outlines the proper sampling procedures and precautions to ensure accurate and representative results.

Sample preparation involves various techniques such as homogenization, grinding, and digestion, depending on the nature of the equipment and the substance being analyzed. It is crucial to follow the specified guidelines to avoid contamination and obtain reliable data.

Analysis and Limitations

The analysis of the restricted substances is typically performed using specific analytical methods, including spectrophotometry, atomic absorption spectroscopy, and chromatography. These techniques allow for precise identification and quantification of the substances in question.

It's important to note that while EN62321-6:2020 provides guidelines for the determination of certain restricted substances, it does not cover all hazardous substances. Therefore, manufacturers and regulators should also consider other relevant standards and regulations to ensure comprehensive control of hazardous materials.

In conclusion, EN62321-6:2020 plays a significant role in promoting the safe use and disposal of electronic and electrical equipment by limiting the presence of hazardous substances. Compliance with this standard not only reduces environmental impact but also protects human health throughout the life cycle of these products.
