AI-generated editorial illustration; not an actual test or certificate.
A laboratory result is useful only when you know which sample was tested, which method was used and what question the analysis was intended to answer. The IEC 62321 series addresses the determination of certain substances in electrotechnical products. It is not a general safety certificate or an automatic guarantee of RoHS compliance.
Series, part and edition
The full reference matters. For example, IEC published IEC 62321-3-1:2026 on 6 May 2026. That part concerns screening by X-ray fluorescence and adds elements compared with the earlier edition. A bare reference to “62321” does not identify the method used.
If you need an EN version or national adoption, check that reference and status separately. Publication of an IEC edition does not establish that every European or national adoption changed at the same time.
Testing does not replace product assessment
RoHS restricts certain substances in electrical and electronic equipment. The European Commission maintains information on scope and exemptions. Before interpreting a report, establish which requirements apply to the product, its materials and the relevant date.
Screening and identifying a specific substance can answer different questions. Do not automatically treat a total-chromium result as identification of hexavalent chromium. Ask the laboratory what the selected method can establish and when further analysis is necessary.
What to request with the report
- Identification of the sample and materials analyzed.
- The complete test-method reference and edition.
- Results, units and relevant interpretation limits.
- The scope of any accreditation being cited.
- An explanation of limitations and how the sample relates to the finished product.
Link each report to a product reference and revision in your document records. When a supplier, coating or material changes, check whether the existing evidence still applies. Keeping a PDF does not settle that question.
Correction to the earlier article
The previous version said the series guaranteed conformity and environmental safety. Those guarantees have been removed. A test’s usefulness depends on its scope and its place in the complete assessment; purchasing a standard does not certify a product.
