IEC 60115-4:2022(E) relates to resistors having a rated dissipation typically greater than 1 W up to and including 1 000 W for use in electronic equipment. This document is applicable to fixed power resistors with a maximum surface temperature (MET) higher than the preferred upper category temperature (UCT) of 200 °C. NOTE Heat sink resistors, i.e. resistors which in their operation depend on being mounted on a dedicated heat sink, owing to their special temperature conditions, are covered by a special sectional specification (under consideration at the time of publication). These resistors are typically described according to types (different geometric shapes) and styles (different dimensions), and product technology. The object of this document is to define preferred ratings and characteristics and to select from IEC 60115-1 the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of resistor. NOTE SMD resistors are covered by IEC 60115-8, regardless of their dissipation. This edition includes the following significant technical changes with respect to the previous edition:
