This method utilizes base thermal capacities derived from standardized testing. It applies a series of modification factors to account for real-world variables like ambient temperature, air velocity, altitude, and duty cycles. It is often favored for catalog ratings and standard industrial applications. The Calculation Framework of Part 2
Organizations such as ANSI (USA), DIN (Germany), BSI (UK), or AFNOR (France) provide localized access and currency conversions for purchasing the document. : The calculation methods are based on theoretical
Recommendation: Download the PDF, skip the introduction, go straight to and Annex B (calculation example) . That’s where the thermal truth lives.

You have a helical gearbox transmitting 150 kW at 1500 rpm. The ambient temperature is 30°C. You want the maximum oil temperature to be 80°C.
If you download the ISO TR 14179-2 PDF, you are not getting dry text. You are getting a for thermal rating. The core of the document is a unique set of cartographic tables that answer one brutal question: How much heat can my gearbox housing actually shed into the environment?
