IEC 60245 is the overarching international standard that defines the requirements. HO7RN-F is a specific type or designation of cable that is manufactured according to that standard.
Think of it like this:
- IEC 60245 is like the recipe book for all rubber-insulated cables.
- H07RN-F is a specific recipe (for a very popular, heavy-duty flexible cable) found inside that book.
One cannot have an H07RN-F cable that does not comply with IEC 60245, the standard is its very definition. When specifying or purchasing, you typically ask for the cable type (H07RN-F), which implicitly means it conforms to the relevant standard (IEC 60245).
In short, IEC 60245 is the “what” and “how” of making rubber cables. HO7RN-F is the “which one” you need for tough, flexible, outdoor industrial applications.
