These are assemblies that strictly conform to an established design that has passed all required type tests, such as temperature rise limits and short-circuit withstand. iec 60439-1 standard pdf

The heat stayed within the limits of the standard’s Table 2. Elias felt a small knot in his chest loosen. But the true test—the "Type Test"—was yet to come.

One of the most critical aspects found within an IEC 60439-1 standard PDF is the distinction between two primary types of assemblies. This classification dictated how a manufacturer could prove compliance. If you'd like, I can help you with
