The laboratory for electromagnetic tests

EL.C.A. has an equipped area for electromagnetic compatibility tests. The in-house laboratory allows measurements to be made on electronic boards and complete equipment to evaluate electromagnetic interference phenomena EMI (electromagnetic interference).
These tests are necessary because electromagnetic waves can cause the malfunction of a electrical system of a device till causing a block and interfere with radio communications. In addition, they represent a danger to health and the environment. In order for products to be marketed safely, many countries have made electromagnetic compatibility testing mandatory. The European Directive 2014/30/EU provides, in fact, that every electrical or electronic device marketed in the European Union is electromagnetic compatible with the surrounding environment, respecting the levels of electromagnetic emissions allowed, without generating intolerable electromagnetic disturbances.

In the laboratory of EL.C.A. Pre-compliance tests are carried out according to European harmonized standards. Specifically, tests are performed with duct-type disturbances (BURST, SURGE, voltage holes) according to IEC 61000-4-4, IEC 61000-4-5, IEC 61000-4-11, IEC 61000-6-1, IEC 61000-6. These tests allow to verify the correct functioning and behaviour of electronic boards and equipment when they are subjected to electromagnetic disturbances due to the power supply network. The disturbances introduced by the product into the electricity grid are also verified.

Another type of test that is analyzed by the EM laboratory are tests with surface electrostatic discharges, according to the IEC 61000-4-2 standard. This makes it possible to ensure that electronic cards and equipment are adequately protected. Uncontrolled electrostatic discharges can cause failures or cause hidden defects in electronic devices (semiconductor devices).
