This part of IEC 60115 is applicable to fixed power resistors for use in electronic equipment. This standard relates to resistors having a rated dissipation typically greater than 1W up to and including 1000W for use in electronic equipment.

These resistors are typically described according to types (different geometric shapes) and styles (different dimensions) and product technology. The resistive element of these resistors is typically - protected by a conformal lacquer coating or - cement coating or - vitreous enamel or - a ceramic body or - any other housing, which is to be described in the relevant specification. The electrical connection of these resistors is typically achieved by means of - lead wire terminations or - punched terminals or lug terminals or - push on terminals or - screw terminals or - any other termination, which is to be described in the relevant specification In special cases, a heat sink may be applicable but not mandatory. The object of this standard is to prescribe 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. Test severities and requirements prescribed in detail specifications referring to this sectional specification shall be of equal or higher performance level, because lower performance levels are not permitted.

The object of this standard is to prescribe 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.

This part of IEC 61400 specifies a method to calculate the design reliability of wind turbines gearboxes covered by IEC 61400‑4, based upon failure modes where standardized calculation methods are publicly available. Currently, not all failure mechanisms that occur in the field have accepted theoretical models. Therefore, the method only provides a quantitative assessment method of the failure mechanisms that can be described with accepted mathematical models for the complete gearbox, stages (functional units), field replaceable units, and individual components. For the calculable failure mechanisms, it is possible to compare the reliability between different gearbox designs within the limitations of the theoretical models. The use of field-based statistical parameters can improve the accuracy of the calculated reliability. The calculated design reliability can provide information for the lifecycle management strategy. However, this document does not provide trade-off decisions between higher design reliability and maintenance strategies (e.g. preventive or predictive maintenance). This document does not consider repairable system analysis. Due to the lack of accepted theoretical models for some failure modes, the model can currently not predict the apparent failure probability in the field. Neither this document nor IEC 61400-4 specify a minimum value of design reliability.
