An important milestone for industry and the technical public was 1992, when the government, in line with the intention to join the EC, decided to orient Czechoslovak technical standardization towards the adoption of EN European standards in the system of ČSN Czechoslovak technical standards. It must be remembered that with regard to the then valid Act no. 30/68 Coll. standards were legally binding documents. The ESČ mark was used as a state approval mark, but in 1992 EZÚ acquired the mark into its ownership and registered it as a trademark.
