The ESČ testing facility was established

The establishment of the electrotechnical testing facility, the development of electrotechnical testing and marking products was a result of the needs of the Czechoslovak electrical industry, which wanted to guarantee the quality and safety of products used by the general public. The establishment of the testing facility dates back to June 1926, when a larger number of fusible plug cartridges were tested at the Czech Technical University in Brno in accordance with ESČ Regulations. In 1928, the association bought a house in Prague where a laboratory for testing conductors and installation material was built. In the same year, ongoing tests of installation pipes and fuses were agreed with manufacturers to help ensure their safety. Products that complied with type tests in accordance with ESČ regulations were granted the right to use the ESČ mark. Lists of tested products, including a description of conducted tests, were subsequently published in the Elektrotechnický obzor (Electrotechnical Horizon) magazine – the predecessor of today’s ELEKTRO magazine.
