The ESČ mark expresses the conformity of the marked products with electrical safety standards. It is one of the oldest symbols for a safe product in the world. It has been awarded since 1926.
At the same time, the ESČ mark is registered at the European Committee for Standardisation (CENELEC) as a Czech mark of conformity with electrical safety standards and is equal to other marks of renowned world testing laboratories.
The EZÚ certificate is awarded by the Testing Institute of Electrical Engineering to products that have successfully passed the type test according to the relevant technical standards on electrical safety or on EMC. The certificate is usually valid for three years.
The products are marked with EZÚ EMC and ESČ logos. The ESČ certificate is available for download here: https://trevos.eu/en/download
