Th
26、e 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-gov
27、ernmental, 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.
28、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 vo
29、te. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

31、ermal stress and strain. This series of International Standards aims in particular at a) establishing specifications for the methods of measuring physical parameters characterising thermal environments; b) establishing methods for assessing thermal stress in cold, moderate and hot environments. The
32、analysis methods described by these latter standards allow the prediction of the average physiological response of subjects exposed to a thermal environment. Some of these methods are not applicable under exceptional climatic circumstances, when the characteristics of the exposed subjects differ gre
33、atly from the average or when special means of protection are used. In these cases, or for the sake of research, it may be useful or even necessary to measure directly the physiological strain experienced by the subject. This International Standard gives a series of specifications concerning the met
34、hods of measurement and interpretation of the physiological parameters considered as reflecting the response of the human organism placed in a hot or cold environment.

35、rmal strain by physiological measurements 1 Scope This International Standard describes methods for measuring and interpreting the following physiological parameters: body core temperature; skin temperatures; heart rate; body-mass loss. The choice of variables to be measured and techniques to be use
36、d is at the discretion of those responsible for the health of the employees. These persons will have to take into account not only the nature of the thermal conditions, but also the degree of acceptance of these techniques by the employees concerned. It should be emphasised that direct measurements
37、on the individual can only be carried out on two conditions. a) If the person has been fully informed about the discomfort and the potential risks associated with the measurement technique and gives free consent to such measurements. b) If the measurements present no risk for the person which is una
38、cceptable in view of general or specific codes of ethics. In order to simplify this choice, Annex A presents a comparison of the different methods concerning their field of application, their technical complexity, the discomfort and the risks that they might involve. This standard defines the condit
39、ions which are to be met in order to ensure the accuracy of the data gathered from the different methods. The measurement methods are described in Annex B. Limit values are proposed in Annex C (informative). This standard is not concerned with experimental conditions for which investigators may deve
40、lop alternative methods intended to improve knowledge in this area. It is however recommended, when conducting such studies in the laboratory, to use the methods described below as references, so that results may be compared. Before using the evaluations methods described in this International Stand
41、ard, the user is required to follow the ethics and legal rules in force in his country or institution. Accordingly, ethical committees will be consulted and rules concerning free written consent, freedom of participation, confidentiality, etc. will be strictly followed. 2 Normative references The fo
