Introduction If you are an electrical engineer, a quality assurance manager, or a procurement specialist working with electrical equipment for measurement, control, or laboratory use, you have likely encountered the requirement: "Compliant with EN 61326-1." en 61326-1 pdf
If your product passed immunity testing under the 2013 version, it will likely fail under the 2021 version due to doubled test levels. You must re-test. Common Pitfalls When Downloading "Free" EN 61326-1 PDFs We have seen many small manufacturers fall into these traps: Pitfall 1: Using an Outdated Withdrawn Standard A Notified Body will reject your Technical File if it references EN 61326-1:2013 after the "date of withdrawal" (DOW). The DOW for the 2013 edition was July 2023 . Using it now is non-compliant. Pitfall 2: Missing Corrigenda or Amendments EN standards often have amendment documents (e.g., A1:2022). Free PDFs rarely include these. The official PDF from CENELEC includes all corrigenda automatically. Pitfall 3: Language Errors Unofficial scans may be in German, French, or a hybrid. For CE marking, you need the English version unless your Notified Body accepts another language. The official PDF lets you choose the language. Pitfall 4: No Print or Copy Features While inconvenient, this is by design. Official PDFs are encrypted to prevent unauthorized distribution. Free PDFs that allow full copying are likely counterfeit. Alternatives to a Single PDF: Standards Suites EN 61326-1 is part of a family. If you are designing a product, you may also need: | Phenomenon | Test Standard | Test level
