ČSN EN IEC 61558-2-1 ed. 3 Tato část IEC 61558 se zabývá bezpečností transformátorů s odděleným vinutím pro obecné aplikace a napájecích zdrojů obsahujících transformátory s odděleným vinutím pro obecné aplikace. Tato norma se také vztahuje na transformátory obsahující elektronické obvody a platí pro napájecí zdroje (lineární), pro spínané napájecí zdroje platí IEC 61558-2-16. Tato norma se nevztahuje na transformátory spadající pod IEC 60076-11. Norma je použitelná pro nepřenosné nebo přenosné, jednofázové nebo vícefázové, vzduchem chlazené (přirozené nebo nucené) samostatné nebo sdružené transformátory suchého typu. Vinutí mohou být zapouzdřená nebo nezapouzdřená. Jmenovité vstupní napětí nepřekračuje AC 1 000 V a jmenovitý vstupní kmitočet a vnitřní pracovní kmitočet nepřekračují 500 Hz.

ČSN EN IEC 63522-27 This part of IEC 63522 is used for testing all kinds of electrical relays and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use. NOTE 1 - Examples for electrical relays in the sense of this document include electromechanical relays, reed relays, reed contacts, reed switches, solid state relays, time relays and technology combinations of these. This document defines a standard test method for electrical contact noise. NOTE 2 - The measurement of electrical contact noise depends on the relay design as well as the complete test setup and is therefore influenced by many parameters. Defining the entire set-up with the customer is effective for electrical contact noise measurement.
