## Ergonomics of the thermal environment — Evaluation of thermal environments in vehicles — Part 4: Determination of the equivalent temperature by means of a numerical manikin

active, Most Current
 Organization: ISO Publication Date: 19 October 2020 Status: active Page Count: 51 ICS Code (Road vehicles in general): 43.020 ICS Code (Ergonomics): 13.180
##### scope:

A human-shaped thermal manikin was designed to conduct assessments of the thermal environment from an ergonomic viewpoint. ISO 14505 part 2 defines the index of the environment, also referred to as the equivalent temperature, measured by such a manikin. Part 4 provides guidelines for extending this definition to predictive purposes and specifies a standard prediction method for the assessment of thermal comfort in vehicles using numerical calculations. Specifically, the following section sets forth a simulated numerical manikin as a viable alternative to the thermal manikin for the purpose of calculating the equivalent temperature.

This portion of ISO 14505 was written with the supposition this standard will be applied to various situations such as the following:

- in the case of experimental facilities that are not prepared,

- in the case of prototypes that are incomplete,

- in the case of conditions that are difficult to simulate in controlled experimental settings,

- in the case that occupants are extrapolated to unknown or virtual environments.
