The Role of EN 61326-1 in Modern Electromagnetic Compatibility Introduction
In an increasingly digitized world, the reliable operation of electronic equipment is paramount, particularly in industrial and laboratory settings where precision is critical. EN 61326-1, titled "Electrical equipment for measurement, control and laboratory use – EMC requirements," serves as the foundational European standard for managing Electromagnetic Compatibility (EMC). It specifies the limits and methods for both electromagnetic emissions and immunity, ensuring that devices neither interfere with other electronics nor fail when exposed to external disturbances. Scope and Application
The standard applies to electrical equipment powered by supplies below 1000 V AC or 1500 V DC. Its scope is broad, covering professional, industrial-process, and educational equipment such as: EN IEC 61326-1:2021 - EMC requirements - iTeh Standards
The EN 61326-1 standard is the essential European framework for the electromagnetic compatibility (EMC) of electrical equipment used in measurement, control, and laboratory environments. As a harmonized standard under the EU EMC Directive 2014/30/EU, it provides manufacturers with a "presumption of conformity," allowing them to apply the CE mark and sell their products within the European Economic Area.
The current version, EN IEC 61326-1:2021, is the European adoption of IEC 61326-1:2020. Scope and Application
This standard applies to electrical equipment operating from a supply or battery of less than 1,000 V AC or 1,500 V DC. It specifically covers:
Measurement and Test Equipment: Multimeters, oscilloscopes, and signal generators.
Control Equipment: Industrial process controllers, transducers, and programmable controllers (PLCs).
Laboratory Equipment: Analytical instruments and In Vitro Diagnostic (IVD) devices. Defined Electromagnetic Environments

Lieutenant Eva Rostova of the International Space Standards Bureau stared at the blinking red light on her console. The new atmospheric processor, a marvel of Martian-Dutch engineering, was scheduled to go live in six hours. But every time she ran the harmonics test, a ghost signal sent the humidity regulator into a spasm.
“It’s the magnetic field,” grumbled her technician, Kael, from under a mess of coolant tubes. “Every time we power the main array, the sensor cables start singing like a choir of angry bees.”
Eva didn’t need bees. She needed a document. Specifically, she needed EN 61326-1.
She pulled up the station’s emergency offline archive. The file name appeared, greyed out and stubborn: IEC 61326-1:2020 - Electrical equipment for measurement, control and laboratory use - EMC requirements - Part 1: General requirements.
“The ‘EN’ version,” she whispered to herself, wiping condensation from the screen. “The European Norm adoption. The redline version. It’s the only one that covers the Terran-Mars frequency drift.”
Outside the porthole, the rusty desert of Mars stretched to the horizon. A dust storm was brewing—charged particles that would turn every unshielded wire into an antenna. If she couldn’t fix the electromagnetic compatibility (EMC) in three hours, the processor would spew toxic perchlorates into the habitat’s air.
Kael crawled out, holding a fried circuit board. “The manual is useless. It says ‘reference EN 61326-1 for immunity test levels.’ But the library only has the old 2013 draft.”
Eva closed her eyes. She remembered her training in Bremen, a grizzled professor hammering a single truth: “Standards are not suggestions. They are the walls that keep the chaos out. Never guess the levels. Find the PDF.”
She made a decision. “Crack the emergency comms laser. One burst.”
“That’s a seventy-thousand-euro burn through the dust,” Kael warned. “For a PDF?”
“For survival.”
The laser fired. For ninety agonizing seconds, data trickled through the storm. Then, with a soft ding, the file appeared on her tablet: en_61326-1_2021.pdf.
She opened it. Page 42, Table 4—Immunity to radiated RF electromagnetic fields. There it was: the test level for her specific frequency band. 10 V/m. Not 3, not 30. 10.
Eva recalculated the shielding thickness. She adjusted the ferrite cores on the sensor cables by two millimeters each. She rewrote the filter parameters.
Two hours and forty-seven minutes later, Kael threw the main breaker. The atmospheric processor hummed to life. The ghost signal did not spasm. The humidity regulator sat still as a stone. The numbers on the console were clean.
Eva leaned back, exhausted, and looked at the PDF icon on her screen. She did not delete it. She renamed it: The Wall That Held.
And somewhere on Earth, in a CENELEC committee room, a team of engineers who had argued for three years over that single 10 V/m limit continued their work, never knowing they had just saved a colony on Mars.
