Electromagnetic Compatibility (EMC) refers to the ability of a device or system to operate in its electromagnetic environment in compliance with requirements without causing intolerable electromagnetic interference to any device in its environment. Therefore, EMC includes two requirements: on the one hand, it refers to the requirement that the electromagnetic interference (EMI) generated by the equipment to the environment during normal operation cannot exceed a certain limit; On the other hand, it refers to the device having a certain degree of immunity to electromagnetic interference in the environment, namely Electromagnetic Susceptibility (EMS).

The electromagnetic compatibility performance of electronic and electrical products is a very important technical indicator, which is not only related to the safety and reliability of the product itself, but also to the protection of the electromagnetic environment. Therefore, meeting EMC's requirements is also a very important condition for products to enter the international market.

The EMC Directive 2004/108/EC specifies the basic protection requirements for electrical and electronic equipment.

The EMC directive limits the electromagnetic radiation of devices to ensure that such devices do not interfere with radio, telecommunications, and other devices when used as expected. The directive also specifies the anti-interference ability of such devices and strives to ensure that they are not subject to radio radiation interference when used as expected. In order to sell your electrical equipment within EU member states, your product must comply with coordinated standards (such as EN55022 and EN55024 for information technology equipment).

EU: CE-EMC, in accordance with Directive 2004/108/EC

The EU EMC Directive 2004/108/EU has been revised to the new Directive 2014/30/EU. After April 2016, new directives will be required for all applicable electrical products sold in the European Union.

The requirements listed in Annex I of this directive remain unchanged. But four key changes were made:

This directive now applies to distributors and importers, not just manufacturers

Additional information required in technical documents

DoC now requires multiple languages to be used

The requirements of the announcement agency have been updated

To maintain EMC compliance, some steps can be taken. Firstly, please ensure that all unified standards listed in the report are up-to-date. Review your technical documents and ensure that all operator information and technical instructions comply with the provisions of Article 18. The updated DoC should refer to 2014/30/EU and clearly identify the products you want to sell.
