Hot environments - Estimation of the heat stress on working man, based on the WBGT-index (wet bulb globe temperature) (ISO 7243:1989)
Gives a method, which can easily be used in an industrial environment for evaluating the stresses on a individual. It applies to the evaluation of the mean effect of heat on man during a period representative of his activity but it does not apply to very short periods, nor to zones of comfort.
Warmes Umgebungsklima - Ermittlung der Wärmebelastung des arbeitenden Menschen mit dem WBGT-Index (wet bulb globe temperature) (ISO 7243:1989)
Diese Norm legt ein Verfahren zur Ermittlung der Wärmebelastung eines Menschen in einem warmen Umgebungsklima fest, das eine schnelle Beurteilung erlaubt und das am Arbeitsplatz einfach eingesetzt werden kann. Es erlaubt die Beurteilung der Wirkung von Wärme auf den Menschen im Mittel über einen Zeitraum, der seiner üblichen Tätigkeit entspricht, jedoch nicht die Beurteilung der Kurzzeit-Wärmebelastung sowie die der Wärmebelastung in der Nähe des Behaglichkeitsbereiches.
Ambiances chaudes - Estimation de la contrainte thermique de l'homme au travail, basée sur l'indice WBGT (température humide et de globe noir) (ISO 7243:1989)
La présente Norme internationale prescrit une méthode pour l'estimation de la contrainte thermique subie par une personne placée en ambiance chaude, permettant un diagnostic rapide et qui soit facilement utilisable en milieu industriel. Elle s'applique à l'évaluation de l'effet moyen de la chaleur sur l'homme pendant une période représentative de son activité, mais elle ne s'applique ni à l'évaluation des contraintes thermiques subies pendant de très courtes périodes, ni à l'évaluation des contraintes thermiques proches des zones de confort.

ISO 7243 : 1989(E) IForeword BS0 (the lnternational Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bedies). The work of preparing International Standards is normally carried out through ISO technical committees. Esch 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, govern- mental 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 7243 was prepared by Technical Committee ISO/TC 159, Ergonomics. This second edition cancels and replaces the first edition (ISO 7243 : 19821, of which it constitutes a minor revision.

ISO 7243 : 1989 (El Introduction This International Standard is one study of thermal environments. of a series (listed in annex D) intended for use in the The aim of this series of International Standards is in particular - the finalization of definitions for terms to be used in methods of measurement, test and interpretation, taking into account those Standards already existing or which are being drafted; - the drafting of specifications relating to the methods p hysical Parameters characterizing thermal environments; of measurement for the selection of one or more methods of interpretation of the Parameters; - the establishment of recommended or maximum values for exposure to ther- mal environments in the regions of comfort and extreme environments (hot and cold 1; - the drafting of specifications relating to the methods of measurement of the ef- ficiency of devices or procedures for individual or collective protection against heat and cold. In the light of the increasing interest being shown in the Problems presented by the ex- posure of individuals to thermal environments and the fact that there are few documents or national Standards in this field, it seemed desirable to publish this Inter- national Standard, without waiting for the complete series to be drafted. The wet bulb globe temperature (VOGT) index is one of the empirical indices representing the heat stress to which an individual is exposed. This index is easy to determine in an industrial environment. The method for evaluating the heat stress based on this index is a compromise between the desire to use a very precise index and the need to be able to carry out control measurements easily in an industrial environ- ment. lt should be regarded as an exploratory method. A method of estimating the thermal stress based on an analysis of the heat exchange . between man and environment allows a more accurate estimation of stress and an analysis of the methods of protection. But with the present technology of measure- ment, the method has the drawback of being longer and more difficult to undertake. Such a method will therefore be used either directly when it is desired to carry out an i
