While acknowledging its limitations (notably a typical deviation of around 14 % from measured values and the inability to identify local hot spots), the method remains the industry benchmark for routine thermal capacity assessment. National adoptions (such as GB/Z 22559.2‑2008 in China, BS ISO/TR 14179‑2:2001 in the UK, and UNI ISO/TR 14179‑2:2024 in Italy) ensure worldwide compatibility.

Many practical thermal rating exercises draw from both parts of the standard. Part 2, however, is often the document of choice when more accuracy or a more comprehensive analysis is required, particularly for non-standard housing geometries, forced cooling, or when in-situ measurements can be performed. iso tr 14179-2 pdf

When natural convection cooling is insufficient, the standard guides engineers in sizing external oil coolers, fans, or forced lubrication systems. It provides the analytical framework for determining how much additional heat rejection capacity is needed. Part 2, however, is often the document of
