Electromagnetic compatibility (EMC) is a critical requirement for measurement, control, and laboratory equipment. Their ability to operate properly in complex electromagnetic environments, without being disturbed or generating interference with other devices, is essential to ensuring the reliability of collected data and operational safety.<\/span><\/span>\u00a0<\/span><\/p>

To ensure these requirements, compliance with specific technical standards is essential. Among the most important regulatory references is\u00a0<\/span><\/span>IEC 61326-1<\/span><\/span><\/b>\u00a0, which defines specific EMC requirements for measuring instruments, control equipment, and devices used in laboratories.\u00a0<\/span><\/span>\u00a0<\/span><\/p>

IEC 61326-1<\/span><\/span><\/b>\u00a0<\/span><\/h3>

IEC\u00a0<\/span><\/span>61326-1<\/span><\/span><\/b>\u00a0states that instruments must:<\/span><\/span>\u00a0<\/span><\/p>

  • Limit<\/span><\/span>\u00a0emissions of both radiated and conducted disturbances\u00a0<\/span>, so as not to interfere with other devices.<\/span><\/span>\u00a0<\/span><\/li><\/ul>
    • Ensure high<\/span><\/span>\u00a0immunity\u00a0<\/span>to phenomena such as electrostatic discharges, electromagnetic fields, fast transients and overvoltages.<\/span><\/span><\/li><\/ul>

      The standard differentiates the requirements based on the operating environment:<\/span>\u00a0<\/span><\/p>

      • Controlled-condition laboratories<\/span><\/span>\u00a0<\/span><\/li><\/ul>
        • Industrial environments<\/span><\/span>\u00a0<\/span><\/li><\/ul>
          • Outdoor environments<\/span><\/span>\u00a0<\/span><\/li><\/ul>

            This classification influences the limits to be respected and the severity of the tests, making it essential to correctly define the usage environment right from the early design stages.<\/span><\/span>\u00a0<\/span><\/p>

            Compliance with these requirements is necessary to obtain:\u00a0<\/span><\/span>\u00a0<\/span><\/p>

            • CE marking<\/span><\/span><\/b>\u00a0according\u00a0<\/span><\/span>to\u00a0<\/span><\/span>EMC Directive 2014\/30\/EU<\/span><\/span><\/b>\u00a0<\/span><\/li><\/ul>
              • CB certification<\/span><\/span><\/b>\u00a0,\u00a0<\/span><\/span>for easier access to international markets through the IECEE scheme.<\/span><\/span>\u00a0<\/span><\/li><\/ul>

                EMC testing for measuring instruments<\/span><\/span><\/b>\u00a0<\/span><\/h3>

                The tests required by IEC 61326-1 include:<\/span><\/span>\u00a0<\/span><\/p>

                Electromagnetic emission test:\u00a0<\/span><\/p>

                • Conducted emissions,\u00a0<\/span>disturbances transmitted through power cables<\/span><\/span>\u00a0<\/span><\/li><\/ul>
                  • Radiated emissions,\u00a0<\/span>airborne disturbances<\/span><\/span>\u00a0<\/span><\/li><\/ul>

                    Electromagnetic immunity test:\u00a0<\/span><\/p>

                    • Electrostatic discharge (ESD)\u00a0<\/span><\/li><\/ul>
                      • Radiated electromagnetic fields (RF)\u00a0<\/span><\/li><\/ul>
                        • Burst (fast electrical transients)\u00a0<\/span><\/li><\/ul>
                          • Surge (overvoltages)\u00a0<\/span><\/li><\/ul>
                            • Voltage drops, short interruptions and variations in the supply voltage\u00a0<\/span><\/li><\/ul>

                              These tests are performed in controlled environments, such as semi-anechoic chambers, to ensure maximum accuracy of the results.<\/span><\/span>\u00a0<\/span><\/p>

                              The value of CB certification\u00a0<\/span><\/span><\/b>\u00a0<\/span><\/h3>

                              Obtaining a<\/span><\/span>\u00a0CB Test Certificate\u00a0<\/span>based on IEC 61326-1 makes it easier to:<\/span><\/span>\u00a0<\/span><\/p>

                              • International recognition of the tests carried out<\/span><\/span>\u00a0<\/span><\/li><\/ul>
                                • Accelerate obtaining national certifications such as CE (Europe), UKCA (UK), FCC (USA) and others<\/span><\/span>\u00a0<\/span><\/li><\/ul>
