What is EN 12127:2012?

EN 12127:2012 is a technical standard that specifies the requirements and testing methods for electromagnetic compatibility (EMC) of industrial, scientific, and medical (ISM) radio-frequency (RF) and high-frequency (HF) devices. It was developed by the European Committee for Electrotechnical Standardization (CENELEC) to ensure that these devices do not interfere with other electronic equipment and maintain safe use.

Scope of EN 12127:2012

The standard applies to ISM RF and HF devices such as diathermy equipment, magnetic resonance imaging systems, and induction heating equipment. It covers both intentional and unintentional radiation, which includes emission, immunity, and functional safety aspects. Compliance with this standard ensures that such devices can coexist and operate correctly in their intended environment without causing harm or interference.

Requirements and Testing Methods

EN 12127:2012 sets out specific requirements that ISM RF and HF devices must meet to ensure EMC. These requirements include limits on radiated and conducted emissions, as well as immunity levels to external disturbances. The standard defines measurement procedures and test conditions for the assessment of compliance. It also provides guidelines on how to mitigate electromagnetic interference and ensure functional safety.

Importance of EN 12127:2012 Compliance

Adhering to EN 12127:2012 is crucial for manufacturers, users, and regulators involved with ISM RF and HF devices. Compliance demonstrates the device's reliability and compatibility, giving users confidence in its performance. It helps manufacturers remove potential barriers to trade, ensuring market access for their products across Europe. Additionally, compliance enables regulatory authorities to protect the public from harmful interference and maintain a harmonized approach to EMC requirements.
