Internet of Things and compliance: CE certification of IoT devices

Born from the combination of sensors and network communication of digital devices, the Internet of Things (IoT) continues to establish itself as the paradigm that redefines the technological and productive ecosystems of information technology. These are electronic devices connected to the Internet for the substantial purpose of collecting and transferring information, automating functions and allowing improved monitoring and control.

Smart devices based on standard communication protocols, suitable for considerably vast application sectors. It ranges from Massive IoT to Mission Critical IoT - in relation to the communication capacity of the applications, their reliability, latency, and the number of connected devices - investing in the sectors of logistics, the "smart home" and the "smart city", factory automation, automotive, but also medicine and safety.


The application areas of the IoT are countless and can be represented as all those contexts in which it is necessary to process information and generate processes to implement the quality of life - as well as the production quality - of end users and companies.

As is known, the Internet of Things takes advantage of production developments in the electronics and wireless communication sectors, encouraging the information retrieval and communication capabilities of household appliances, surveillance and security systems, wearable and healthcare devices, related to home automation, robotics, farming, but also transport, self-driving cars and much more.

Focal technologies underlying the Internet of Things, computational platforms - such as the well-known Arduino and Raspberry - Wi-Fi and Bluetooth networks, integrated by Edge Computing - decentralized IT architectures - to deal with problems of latency, reliability and so on, and process large amounts of data in real time.

The marketing of these devices - clearly subject to CE certification of the products themselves - continues to benefit from solid growth. According to today's estimates, in 2015 the IoT presence on the market stood at 18 billion connected devices; devices which - according to forecasts - will reach around 50 billion in 2020.

How to obtain the CE mark on IOT devices

There CE certification it is an essential element for the marketing of IoT products on the European market, guaranteeing the consumer the conformity of the product itself with all the provisions of the European Community. The obligations regarding CE certification, as regulated by the decision of the European Parliament and of the Council n. 768/2008/EC, fall on the various economic operators involved, be they manufacturer, authorized representative, importer or distributor.

The main obligations include that of drawing up, or having a competent laboratory such as Sicom Testing draw up, the product conformity assessment procedure, the EU declaration of conformity, preparing a technical file for the CE marking. The technical file in question - documentary demonstration of the object's compliance with current directives - must be kept for ten years. Furthermore, essential obligations for the CE certification of products are the affixing of the CE mark (which must be visible, legible and indelible) as well as the sudden implementation of corrective actions if the product placed on the market turns out not to comply with Community directives European.

To draft the EU declaration of conformity and obtain CE certification of the products, IoT devices must be subject to tests and evaluation tests that confirm their compliance with current directives. Among the relevant assessments - and carried out by Sicom Testing - are:

  • Conformity tests during the certification and pre-testing process during the product design phase; tests for production control throughout the life of the product itself;
    Tests for certification electromagnetic compatibility, to verify the performance of the product and its immunity to external disturbances;
  • Radio tests for the certification of the full communication functionality of devices that integrate Wi-Fi and Bluetooth;
  • Human exposure testing and SAR, for the verification of the "Specific Absorption Rate" for devices used near the ear and the body, particularly necessary for wireless devices and "wearable devices";
  • Electrical safety tests, for the verification of conformity of electrical and electronic IoT equipment with the essential requirements of the LVD directive;
  • Tests on small and large household appliances for domestic and industrial use: testing activities on household appliances that involve the integration of radio technologies, a key element of the IoT.

  1. Good evening, I am designing an edge computing system, all the hardware components are CE certified, do I still have to certify the entire system or can I consider myself "certified" given the documentation of the assembled material?

    • Good morning,

      Compliance with the applicable directives must be verified on the finished product, so that it can be marketed on the European market.
      Depending on the type of product, different directives are applied. For example, the EMC and Low Voltage directives apply to electrical and electronic devices connected to the electricity grid. If they also have radio functionality, they fall under the radio directive which also includes the requirements of the previous ones.
      The product must be tested according to suitable harmonized standards, to demonstrate compliance with the requirements of the applicable directives.
      The product documentation and reports of the tests carried out must be collected in a technical file.
      The product declaration of conformity must be prepared and signed by the manufacturer.
      Sicom Testing can carry out the tests for you and prepare the technical file and the declaration of conformity.

      Best regards
      Sicom Test
