Ergonomics of the thermal environment - Estimation of thermal insulation and water vapour resistance of a clothing ensemble (ISO 9920:2007)
This International Standard specifies methods for estimating the thermal characteristics (resistance to dry heat loss and evaporative heat loss) in steady-state conditions for a clothing ensemble based on values for known garments, ensembles and textiles. It examines the influence of body movement and air penetration on the thermal insulation and water vapour resistance . This International Standard does not deal with other effects of clothing, such as adsorption of water, buffering or tactile comfort, take into account the influence of rain and snow on the thermal characteristics, consider special protective clothing (water-cooled suits, ventilated suits, heated clothing), or deal with the separate insulation on different parts of the body and discomfort due to the asymmetry of a clothing ensemble.
Ergonomie der thermischen Umgebung - Abschätzung der Wärmeisolation und des Verdunstungswiderstandes einer Bekleidungskombination (ISO 9920:2007)
Diese Internationale Norm legt Verfahren zur Abschätzung der thermischen Kennwerte (Widerstand gegen den Verlust an trockener Wärme und Verdunstungswiderstand) unter stationären Prüfbedingungen für eine Bekleidungskombination fest, die sich auf Werten für bekannte Kleidungsstücke, Bekleidungskombinationen und Textilien begründet. Sie behandelt den Einfluss von Körperbewegungen und des Luftdurchgangs durch die Kleidung auf die Wärmeisolation und den Verdunstungswiderstand.
Diese Internationale Norm behandelt nicht
andere Wirkungen der Bekleidung wie Wasseraufnahme, Pufferwirkung und Tragekomfort,
den Einfluss von Regen und Schnee auf die thermischen Kennwerte,
spezielle Schutzkleidung (wasser oder luftgekühlte Anzüge, beheizte Kleidung) und
die örtliche Wärmeisolation an verschiedenen Körperteilen und die Unbehaglichkeit infolge der Asymme¬trie der Bekleidungskombination.

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 9920 was prepared by Technical Committee ISO/TC 159, Ergonomics, Subcommittee SC 5, Ergonomics
of the physical environment.
This second edition cancels and replaces the first edition (ISO 9920:1995), which has been technically revised.
It includes major changes to the sections on clothing vapour resistance as well as those dealing with the
effects of air movement and body motion on clothing insulation and vapour resistance.
