IEC 61558-2-20:2010 deals with the safety of small reactors for general applications. This part is applicable to stationary or portable, single-phase or polyphase, air-cooled (natural or forced) general purpose reactors including alternating current, premagnetised and current compensated independent or associated reactors.
