22、n 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

23、 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. Inter

24、national 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. Publicat

25、ion 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 righ

26、ts. 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 coop

27、eration between ISO and CEN (Vienna Agreement). ISO 13732 consists of the following parts, under the general title Ergonomics of the thermal environment Methods for the assessment of human responses to contact with surfaces: Part 1: Hot surfaces Part 2: Human contact with surfaces at moderate temper

28、ature Technical Specification Part 3: Cold surfaces Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 20/05/2009 06:52, Uncontrolled Copy, (c) BSIBS EN ISO 13732-1:2008ISO 13732-1:2006(E) ISO 2006 All rights reserved vIntroduction When human skin comes into contact with a hot solid surface, bur

29、ns may occur. Whether or not they do depends on a number of factors, the most important of which are the temperature of the surface, the material of the surface, the period of contact between the skin and the surface, the structure of the surface, and the sensitivity of the human being who comes int

30、o contact with the surface (e.g. child or adult). Other factors can also play a part but are of minor importance. In Annex A the scientific background is presented and in the Bibliography publications concerning the objective are listed. This part of ISO 13732 contains a collection of temperature th

31、reshold values for burns when the skin is in contact with a hot solid surface (Clause 4). It also contains a method for the assessment of the risk of burning, i.e. the application of the provided ergonomics data within a risk assessment procedure (Clause 5). A further application of the data may be

32、the specification of temperature limit values for hot surfaces. Such temperature limit values may be specified in product standards or in regulations in order to prevent human beings sustaining a burn when in contact with the surface of a hot product. Guidance on how to select reasonable temperature

33、 limit values for that purpose is given in Clause 7. For different products with the same risk of burning it is reasonable to establish identical surface temperature limit values. Therefore, this part of ISO 13732 provides the possibility of harmonizing such temperature limit values for all kind of

34、products. Touching a hot surface may take place intentionally, e.g. to operate an electrically or gas powered machine or tool, or unintentionally, when a person is near a hot object. The period of contact with the hot surface will be different if the object is touched intentionally than if it is tou

35、ched unintentionally. Considering human reaction times and their distribution in the population, 0,5 s is the minimum applicable contact period for unintentional touching of a hot surface for healthy adults on an acceptable safety level. For intentional touching the minimum applicable contact period

36、 will be longer. For the application of this part of ISO 13732, it is essential to select a contact period which best represents the real circumstances when a hot product is touched. Guidance for such selection is given in Annex B. The ergonomics data provided in this part of ISO 13732 are mainly ba

37、sed on scientific research and represent, as far as is known, the behaviour of the human skin when in contact with a hot surface. Some of the data (e.g. burn threshold data for very short contacts of 0,5 s) are not directly based on scientific research but are deduced by extrapolation of the known t

38、hreshold curves or by reasonable conclusion using scientific results. The temperature threshold values provided in this part of ISO 13732 are valid for burning the skin when in contact with hot surfaces. For the time being there are not sufficient scientific data available on the effects of discomfo

39、rt and pain to for them to be included in this part of ISO 13732. Some data for pain can be derived from national standards (see Annexes A and the Bibliography). Research projects are planned for obtaining data for discomfort and pain. When the results of these projects are available, this part of I

40、SO 13732 may be revised in order to also include discomfort and pain temperature threshold values. ISO 13732-2 deals also with discomfort. This part of ISO 13732 does not provide burn data on the skin that comes into contact with liquids or gases. NOTE With the exception of water there are no such d

41、ata available up to now. For water and liquids with similar heat capacity and heat flow properties burn threshold values for bare metals can be chosen.

43、cope This part of ISO 13732 provides temperature threshold values for burns that occur when human skin is in contact with a hot solid surface. It also describes methods for the assessment of the risks of burning, when humans could or might touch hot surfaces with their unprotected skin. This part of

44、 ISO 13732 also gives guidance for cases where it is necessary to specify temperature limit values for hot surfaces; it does not set surface temperature limit values. NOTE 1 Such temperature limit values can be specified in specific product standards or in regulations in order to prevent human being

45、s sustaining burns when in contact with the hot surface of a product. This part of ISO 13732 deals with contact periods of 0,5 s and longer. It is applicable to contact when the surface temperature is essentially maintained during the contact (see 4.1). It is not applicable if a large area of the sk

46、in (approximately 10 % or more of the skin of the whole body) can be in contact with the hot surface. Neither does it apply 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

47、 can be more serious for the individual, for example: burns resulting in the restriction of airways; large burns (more than 10 % of the body surface) that can impair the circulation by fluid loss; heating of a large proportion of the head or whole body that could lead to unacceptable heat strain eve

48、n in the absence of burning. This part of ISO 13732 is applicable to the hot surfaces of all kind of objects: equipment, products, buildings, natural objects, etc. For the purposes of simplification, it mentions only products; nevertheless, it applies to all other objects as well. It is applicable t

49、o products used in any environment, e.g. in the workplace, in the home. It is applicable to hot surfaces of products that may be touched by healthy adults, children, elderly people and also by people with physical disabilities. It does not provide data for the protection against discomfort or pain.
