Using Annex A of the PDF, list all required EMC tests, ports to be tested, and performance criteria. This plan is what you give to an EMC test house.
Here is the legitimate process to obtain the EN 61326-1 PDF for your engineering library.
Keep your purchase receipt and the PDF file for at least 10 years. Notified bodies frequently ask for proof of standards reference during audits.
Pro Tip: Some companies subscribe to standards portals (e.g., IHS Markit, TechStreet) for unlimited access. This is cost-effective if you need multiple standards.
The standard ensures that electrical equipment functions satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to other equipment in that environment. In simpler terms: it ensures your device doesn’t glitch when near a radio, and your device doesn’t crash the radio.

The EN 61326-1 standard is the primary European regulation for the Electromagnetic Compatibility (EMC) of electrical equipment used in measurement, control, and laboratory environments. As the European adoption of the international IEC 61326-1 standard, it provides a "presumption of conformity" with the EU's EMC Directive (2014/30/EU), which is essential for obtaining the CE mark. Scope and Applicability
The standard applies to electrical equipment operating from a supply or battery of less than 1,000 V AC or 1,500 V DC. It covers equipment used for:
Measurement and Test: Oscilloscopes, multimeters, and signal generators.
Control: Process controllers, programmable logic controllers (PLCs), and intelligent actuators.
Laboratory Use: Analytical equipment and In Vitro Diagnostic (IVD) devices. Defined Electromagnetic Environments
EN 61326-1 classifies equipment based on its intended environment, as testing levels and limits vary significantly between them: IEC 61326-1 General EMC Requirements Testing
The EN 61326-1 standard outlines Electromagnetic Compatibility (EMC) requirements for electrical equipment intended for measurement, control, and laboratory use. Core Content of EN 61326-1
The standard ensures that electrical equipment does not interfere with other devices and remains immune to electromagnetic disturbances in its environment. It divides requirements into two main areas:
Electromagnetic Emissions: Controls the amount of electromagnetic energy a device radiates or conducts into its surroundings. Using Annex A of the PDF, list all
Electromagnetic Immunity: Sets levels of resistance against external disturbances, such as static electricity (ESD), radio-frequency fields, and power surges. Classification of Environments
The standard applies different testing limits based on where the equipment is used:
Basic Electromagnetic Environment: Standard laboratory or commercial areas.
Industrial Electromagnetic Environment: Locations with higher levels of interference, such as factories with heavy machinery.
Controlled Electromagnetic Environment: Areas with specialized mitigation, like shielded rooms. Standard Test Categories
A typical test report for this standard (found in documents like this example test report) includes:
Radiated and Conducted Emissions: Testing interference via airwaves and power lines.
Electrostatic Discharge (ESD): Resistance to static shocks from human touch.
Radio-Frequency (RF) Field Immunity: Ensuring the device works near wireless transmitters.
Electrical Fast Transients (Burst): Protection against sudden voltage spikes. Pro Tip: Some companies subscribe to standards portals (e
Surge Immunity: Resistance to high-energy spikes like those from lightning or heavy switching. Accessing the Full Document
Official versions of the standard are copyrighted and typically must be purchased. You can find digital copies or previews through these platforms:
Scribd: Host several versions of the CEI EN 61326-1 document for online viewing.

EN IEC 61326-1:2021 is the harmonized European standard for electromagnetic compatibility (EMC) in electrical equipment used for measurement, control, and laboratory purposes. It defines mandatory immunity and emission criteria, including ESD, radiated RF, and surge testing, classifying equipment for basic, industrial, or controlled environments. The full standard, including technical specifications, can be purchased via authorized bodies like the CENELEC Shop. EN 61326-1
| Aspect | 2013 Edition | 2021 Edition | |--------|--------------|---------------| | Immunity test levels | 3 V/m for radiated RF (most ports) | 10 V/m for industrial environments | | Radiated RF frequency range | 80 – 1000 MHz | 80 – 1000 MHz plus 1.4 – 2.7 GHz | | Conducted RF | 3 V (0.15 – 80 MHz) | 10 V (0.15 – 80 MHz) | | Performance Criterion | A, B, C | A, B, C (with clarified definitions) | | Documentation requirements | Basic test report | Detailed "Technical Construction File" |
Key takeaway: 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.
Your EN 61326-1 pdf will contain tables specifying test levels for:
Important note: EN 61326-1 allows reduced test levels for battery-operated or portable equipment when justified.
A unique feature of EN 61326-1 is the classification of how the device behaves during immunity testing. The PDF defines these criteria clearly:
