TABLE OF CONTENTS Listed here are some categories of component application processes that may be documented in a Plan. Not all of the categories listed below are relevant to every component application; therefore, the requirements listed below are applicable only if relevant to the given application.
The documented processes shall verify that the selected components satisfy the functional requirements for each application.
| Note | Examples of these processes include analysis, modelling, simulation, and testing. If software is used for any of these processes, it should be described briefly. |
EMC is demonstrated by analysis, testing and simulation. The EMC guidelines shall form part of the design process. The component performance shall be capable of EMC compliance at the equipment level.
| Note | Certain components e.g., high power switching components, may produce more electromagnetic signal than other types and additionally certain components can be more susceptible to electromagnetic interference than others. |
The documented processes shall verify that the component is used within the operating limits specified by the component manufacturer per a documented set of derating criteria.
When the component manufacturer provides derating criteria and methods, they shall be used where applicable. If the component manufacturer does not provide this information, or if it is not applicable, then the Plan owner shall develop and document appropriate derating criteria and methods. All instances in which a component is not used within the limits defined above shall be documented in the design records. In all...
