Yes, the method is generally applicable to standard materials like sheet steel, aluminum, and insulating materials. However, the 2022 edition includes a new annex specifically addressing the effect of different enclosure materials on thermal performance.

Heat escapes the enclosure through its walls, top, and bottom. The calculation factor changes based on how the enclosure is installed. For example, a free-standing enclosure dissipates heat better than a flush-mounted wall enclosure. 3. Ventilation Factor iec tr 60890 pdf

This is not a physical testing standard; it is an analytical tool used primarily for design verification. It allows engineers to determine whether the temperature inside an enclosure will exceed the maximum permissible limits for the installed components, helping to ensure safe and reliable operation under expected load conditions.
