Why CE Marking?

The European CE marking regulation has been mainly set up to:

1. Harmonize all varying national regulations for consumer and industrial products in European Member States, so that the Single Market is encouraged;
2. Bring about cost savings for producers;
3. Enhance the safety of products;
4. Supply public bodies with a uniform procedure that can be checked.In the past, product requirements and test procedures in Europe were set by the individual Member States of the European Union. This meant that, for example, companies that wanted to sell their products on the European market sometimes had to deal with more than ten different technical requirements or procedures for just one product. The existence of all the different national legislation was contrary to the aim of the European Union in realizing one Single Market, in which there would be a free circulation of goods (as well as a free circulation of persons, services and capital).

All the different product requirements brought many costs for the producers. With the help of the CE marking Directives or ‘New Approach’ Directives, the measures have been optimized by setting up European (European-wide) requirements, the harmonization of national legislation and directives, standards and mutual recognition of the technical standards, tests methods (compliance tests) and test laboratories, so that producers no longer need to adapt their products to the different markets.

During the process of harmonization the safety level of all products was attuned and raised. In most European countries, safety and health had already been the subject of directives for many years but the safety level was not always satisfactory.

With the help of the conformity assessment procedures, the authorities can ascertain that the products that are placed on the market comply with the requirements as stated in the regulations of the directives. The CE marking is consequently largely for the benefit of the authorities. However, safe products are also necessary for the end user in the work or consumer environment.

What is Radiated Emission test?

Radiated Emission is only one of the Electromagnetic Compatibility (EMC) tests. It is a test that must be performed in an anechoic chamber  or Open Area Test Site (OATS) after the EMC standard has been determined. This standard has to be determined according to the product. Radiated Emission testing is to determine whether the intended product is below a certain level of unwanted electromagnetic frequencies. If the measurement results of a product is under the limit value stated on the standard, this test is counted as PASS. If measurements exceed the limit, it is necessary to make improvements on the product in terms of design change or EMC. The work done on this kind of product is R & D work and it is very essential for manufacturers.

The measurement frequency range of Radiated Emission tests usually starts from 30 MHz and can be up to 1 GHz, 2 GHz or 6 GHz depending on the product specification and the standard applied. Measurements are made via antennas designed for specified frequencies and measuring devices called EMI Receivers. The measurement distance between the product and the antenna is typically 3 meters or 10 meters. It is also possible to change the limits according to the measurement distance. For instance, a limit value of 40 dBuV/m at 3 meters can be reduced to 30 dBuV/m at 10 meters.

Radiated Emission test is one of the most basic tests of EMC tests and is a test that the product designers need to be aware of. Precautions related to the EMC testing of a product must be initiated at the design stage of the product and should continue during the serial production phase. Even when the product is at the end user, precautions should be followed.

New Radio Equipment Directive 2014/53/EU

The Radio and Telecommunications Terminal Equipment Directive (1999/5 / EC), which had been used for the CE marking of wireless devices, has left its place to the new Radio Equipment Directive (2014/53 / EU) since 13 June 2017.

Manufacturers, importers, exporters and distributors who will carry out CE marking rules on their wireless devices are required to take the necessary precautions. You can access the English version published in the Official Journal of the EU here: RED: Radio Equipment Directive (2014/53/EU)
