IEC standards cover a vast range of technologies within electrotechnology. The numbers of older IEC standards were converted in 1997 by adding 60000; for example IEC 27 became IEC 60027. IEC standards often have multiple sub-part documents; only the main title for the standard is listed here. IEC 60027 Letter symbols to be used in electrical ...
A list of standards published by the International Electrotechnical Commission. A list of IEC standards is available as well. Wikimedia Commons has media related to IEC standards .
Example IEC categories in standard 60947 are described as: AC-1 - Non-inductive or slightly inductive loads, resistance furnaces; AC-2 - Starting of slip-ring motors: starting, switching-off; AC-3 - Starting of squirrel-cage motors and switching-off only after the motor is up to speed. (Make Locked Rotor Amps (LRA), Break Full Load Amps (FLA))
IEC Standards that are not jointly developed with ISO have numbers in the range 60000–79999 and their titles take a form such as IEC 60417: Graphical symbols for use on equipment. Following the Dresden Agreement with CENELEC the numbers of older IEC standards were converted in 1997 by adding 60000, for example IEC 27 became IEC 60027 ...

These components are deemed "well-tried components" and are listed in ISO 13849-2, Annexes A through D. Additionally, components that have been tested by the manufacturer and approved according to the relevant component safety standard, e.g., IEC 60947-5-5, are also considered well-tried. Since Category 1 is single channel, DC avg = NONE. CCF ...
