EN ISO 13732-1:2006

Ergonomics of the thermal environment - Methods for the assessment of human responses to contact with surfaces - Part 1: Hot surfaces (ISO 13732-1:2006)

This standard provides temperature threshold values for the occurrence of burns when the human skin is in contact with a hot solid surface.
This standard also describes methods for the assessment of the risks of burning, when humans can or may touch hot surfaces with the unprotected skin.
This standard also gives guidance when it is necessary to specify temperature limit values for hot surfaces. This standard gives guidance but does not set surface temperature limit values.
NOTE 1   Such temperature limit values may be specified in specific product standards or in regulations in order to prevent human beings to sustain burns when in contact with the hot surface of  a product.
This standard applies to contact periods of 0,5 s and longer.
This standard is not applicable if a large area of the skin (approximately 10 % or more of the skin of the whole body) can be in contact with the hot surface. This standard is also not applicable to skin contact of more than 10 % of the head or contact which could result in burns of vital areas of the face.
NOTE 2   In some cases the results of contact with a hot surface may be more serious for the individual, e.g.:
· burns resulting in the restriction of airways;
· large burn (more than 10 % of the body surface) may impair the circulation by fluid loss;
· heating of a large proportion of the head or whole body may lead to unacceptable heat strain even in the absence of burning.
This standard applies to hot surfaces of all kind of objects: equipment, products, buildings, natural objects, etc. In order to simplify the standard only products are mentioned herein, but it applies to all other objects, too.
This standard applies to products used in any environment, e.g. workplaces, the home etc..
This standard applies to hot surfaces of products which may be touched by healthy adults, children, elderly people and also by people with physical disabilities.

Ergonomie der thermischen Umgebung - Bewertungsverfahren für menschliche Reaktionen bei Kontakt mit Oberflächen - Teil 1: Heiße Oberflächen (ISO 13732-1:2006)

Dieser Teil von ISO 13732 stellt Temperaturschwellenwerte für Verbrennungen zur Verfügung, die auftreten, wenn es zum Kontakt der menschlichen Haut mit einer heißen, festen Oberfläche kommt.
Sie beschreibt außerdem Verfahren zur Bewertung von Verbrennungsrisiken in Situationen, in denen Menschen heiße Oberflächen mit ihrer ungeschützten Haut berühren können oder dürfen.
Dieser Teil von ISO 13732 gibt auch Leitlinien für Fälle, in denen es erforderlich ist, Temperaturschwel¬lenwerte für heiße Oberflächen festzulegen. Sie legt jedoch keine Grenzwerte für Oberflächentemperaturen fest.
ANMERKUNG 1   Um zu verhindern, dass Menschen bei Berühren der heißen Oberfläche eines Produktes Verbrennungen davontragen, können derartige Temperaturgrenzwerte in besonderen Produktnormen oder in Vorschriften festgelegt werden.
Dieser Teil von ISO 13732 gilt für eine Kontaktdauer von 0,5 s und länger.
Sie ist anwendbar für Kontakte bei denen die Oberflächentemperatur während des Kontaktes in Wesentlichen unverändert bleibt (siehe 4.1).
Sie ist nicht anwendbar, wenn ein großer Bereich der Haut (etwa 10 % oder mehr der Körperoberfläche) mit einer heißen Oberfläche in Berührung kommen kann. Sie ist ebenfalls nicht anwendbar bei einem Hautkontakt von mehr als 10 % des Kopfes oder einem Kontakt, der Verbrennungen von lebenswichtigen Bereichen des Gesichtes zur Folge hat.
ANMERKUNG 2   In einigen Fällen kann der Kontakt mit einer heißen Oberfläche für eine Person noch schwerwie¬gender sein, z. B.:
   Verbrennungen, die zu einer Verengung der Atemwege führen;
   großflächige Verbrennungen (von mehr als 10 % der Körperoberfläche) können den Blutkreislauf durch Flüssigkeits¬verlust beeinträchtigen;
   die Erhitzung eines großen Teils des Kopfes oder des gesamten Körpers kann selbst ohne das Auftreten einer Verbrennung zu einer nicht akzeptablen Hitzebeanspruchung führen.

Ergonomie des ambiances thermiques - Méthodes d'évaluation de la réponse humaine au contact avec des surfaces - Partie 1: Surfaces chaudes (ISO 13732-1:2006)

La présente norme indique des valeurs seuil de température auxquelles des brûlures interviennent lorsque la peau de l'être humain entre en contact avec une surface solide chaude.
Elle décrit également des méthodes permettant d'évaluer les risques de brûlure lorsque des personnes peuvent ou sont susceptibles de toucher des surface chaudes sans que leur peau ne soit protégée.
La norme, qui donne également des indications lorsqu'il est nécessaire de spécifier des valeurs limites de températures pour des surfaces chaudes, n'établit nullement de valeurs limites de températures des surfaces.
NOTE 1   Ces valeurs limites de température peuvent être spécifiées dans des normes de produits ou dans des règlements afin d'éviter que des personnes ne subissent de brûlures si elles touchent la surface chaude d'un produit.
La présente norme concerne des durées de contact de 0,5 s et plus.
La présente norme n'est pas applicable si une surface importante de peau (environ 10 % ou plus de la peau de l'ensemble du corps) peut être en contact avec la surface chaude. Elle ne s'applique pas non plus dans les cas de contact avec plus de 10 % de la tête ou de contacts susceptibles d'engendrer des brûlures des zones vitales du visage.
NOTE 2   Dans certains cas, le contact avec la surface chaude peut avoir des conséquences plus graves pour l'individu, il peut, par exemple provoquer :
-   des brûlures engendrant une limitation de la capacité des voies respiratoires ;
-   une brûlure étendue (recouvrant plus de 10 % de la surface du corps) susceptible d'entraver la circulation par perte de liquides ;
-   un échauffement d'une grande proportion de la tête ou de la totalité du corps, pouvant engendrer une contrainte thermique inacceptable, même en l'absence de brûlures.
La présente norme s'applique aux surfaces chaudes de toutes sortes d'objets : équipements, produits, bâtiments, objets naturels, etc.. Par souci de simplification la norme ne concerne que des produits, mais elle est également appl

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 13732-1 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 122, Ergonomics, in collaboration with Technical Committee ISO/TC 159, Ergonomics,
Subcommittee SC 5, Ergonomics of the physical environment, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).

Introduction
When human skin comes into contact with a hot solid surface, burns may occur. Whether or not they do
depends on a number of factors, the most important of which are
