Ergonomics of the thermal environment - Evaluation of thermal environments in vehicles - Part 2: Determination of equivalent temperature (ISO 14505-2:2006)
ISO 14505-2:2006 provides guidelines for the assessment of the thermal conditions inside a vehicle compartment. It can also be applied to other confined spaces with asymmetric climatic conditions. It is primarily intended for assessment of thermal conditions, when deviations from thermal neutrality are relatively small. Appropriate methodology as given in ISO 14505-2:2006 can be chosen for inclusion in specific performance standards for testing of HVAC-systems for vehicles and similar confined spaces.
Ergonomie der thermischen Umgebung - Beurteilung der thermischen Umgebung in Fahrzeugen - Teil 2: Bestimmung der Äquivalenttemperatur (ISO 14505-2:2006)
Dieser Teil von ISO 14505 enthält Leitlinien für die Beurteilung der thermischen Bedingungen in einem Fahrzeug. Er kann auch für andere geschlossene Räume mit asymmetrischen Klimabedingungen angewendet werden. Er ist in erster Linie für die Beurteilung der thermischen Bedingungen vorgesehen, wenn die Abweichungen von der thermischen Neutralität relativ klein sind. Eine geeignete Methodologie, wie sie in diesem Teil von ISO 14505 angegeben ist, kann ausgewählt werden, um in speziellen Anforderungsnormen zur Prüfung von HVAC Anlagen für Fahrzeuge und ähnliche geschlossene Räume berücksichtigt zu werden.
Ergonomie des ambiances thermiques - Évaluation des ambiances thermiques dans les véhicules - Partie 2: Détermination de la température équivalente (ISO 14505-2:2006)
L'ISO 14505-2:2006 donne des lignes directrices relatives à l'évaluation des conditions thermiques à l'intérieur d'un habitacle de véhicule. Elle peut également s'appliquer à d'autres espaces confinés où règnent des conditions climatiques asymétriques. Elle est essentiellement destinée à l'évaluation des conditions thermiques, lorsque les écarts par rapport à la neutralité thermique sont relativement faibles. L'une des méthodes appropriées décrite dans l'ISO 14505-2:2006 peut être choisie pour être incluse dans des normes de performance spécifiques en vue d'essayer les systèmes de chauffage, de ventilation et de climatisation (système CVCA) des véhicules et les espaces confinés analogues.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 14505-2 was prepared by Technical Committee ISO/TC 159, Ergonomics, Subcommittee SC 5,
Ergonomics of the physical environment.
ISO 14505 consists of the following parts, under the general title Ergonomics of the thermal environment —
Evaluation of thermal environments in vehicles:
⎯ Part 1: Principles and methods for assessment of thermal stress [Technical Specification]
⎯ Part 2: Determination of equivalent temperature

Introduction
The interaction of convective, radiative and conductive heat exchange in a vehicle compartment is very
complex. External thermal loads in combination with the internal heating and ventilation system of the vehicle
create a local climate that can vary considerably in space and time. Asymmetric thermal conditions arise and
these are often the main cause of complaints of thermal discomfort. In vehicles without or having a poor
heating, ventilating and air-conditioning system (HVAC-system), thermal stress is determined largely by the
impact of the ambient climatic conditions on the vehicle compartment. Subjective evaluation is integrative, as
the individual combines into one reaction the combined effect of several thermal stimuli. However, it is not
sufficiently detailed or accurate for repeated use. Technical measurements provide detailed and accurate
information, but require integration in order to predict the thermal effects on humans. Since several climatic
factors play a role for the final heat exchange of a person, an integrated measure of these factors,
representing their relative importance, is required.
