In 1996, EZÚ joined the European CENELEC Certification Agreement – CCA, within which CCA certificates are issued and tests conducted in accordance with EN standards under the Low Voltage Directive. It pushed the ESČ mark through within the CCA as the national mark of conformity of products with electrical safety standards. EZÚ subsequently joined the ENEC system for the safety of luminaires and other products and the HAR system for the safety and quality of cables and cords, which are more important certification services than the CCA system today.
