IEC 60861:2006 outlines the technical specifications for equipment designed to monitor alpha-, beta-, or gamma-emitting radionuclides in liquid effluents and surface waters. It provides general guidance on the detection capabilities of such equipment and indicates when and where its use may be practical. Notably, alpha monitoring in liquids has been demonstrated using a concentration device

IEC 60860:2014 pertains to equipment designed to detect gamma radiation, neutrons, or both, in order to provide warnings of a criticality accident. It primarily focuses on equipment design and does not cover the placement of such devices. The necessity for criticality alarm systems and their operational procedures are detailed in ISO 7753 and ISO 11320.

IEC 60850:2014 defines the key characteristics of supply voltages for traction systems, including traction fixed installations, auxiliary devices powered by the contact line, and rolling stock, for use in the following applications: Railways; Guided mass transit systems such as tramways, light trains, elevated and underground railways, and trolleybus systems; Rail-bound material transport systems, such as

The present International Standard outlines the primary features of supply traction systems, encompassing traction fixed installations, auxiliary devices, contact lines, and rolling stock, for use in the following contexts: Underground and elevated railways; Guided mass transit systems, such as tramways, mountain railways, and trolleybus systems; Material handling systems. This standard does not cover: Traction systems

IEC 60836:2015 provides specifications and testing procedures for unused silicone liquids that are intended for use in transformers and various electrotechnical devices. The defined characteristics of silicone transformer liquid categorized as L-NTUK-8360300, as per IEC 61 039, are detailed in Table 1. In addition to standard transformer applications, silicone liquids are also employed in other
