28、duction 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 the temperature of the surface, the material of the surface, the period of contact between the skin and the surface, the struct

29、ure of the surface, and the sensitivity of the human being who comes into 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 ar

30、e listed. This part of ISO 13732 contains a collection of temperature threshold 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 as

31、sessment procedure (Clause 5). A further application of the data may be 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 su

32、rface of a hot product. Guidance on how to select reasonable temperature 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 p

33、ossibility of harmonizing such temperature limit values for all kind of 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 wi

34、ll be different if the object is touched intentionally than if it is touched 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 safe

35、ty level. For intentional touching the minimum applicable contact period 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

36、 B. The ergonomics data provided in this part of ISO 13732 are mainly based 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 base

37、d on scientific research but are deduced by extrapolation of the known threshold 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

38、 are not sufficient scientific data available on the effects of discomfort 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 an

39、d pain. When the results of these projects are available, this part of ISO 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 wit

40、h liquids or gases. NOTE With the exception of water there are no such data 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. DIN EN ISO 13732-1:2008-12 EN ISO 13732-1:2008 (E)4 1 Scope This part of ISO

41、 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 ISO 13732 also gives

42、 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 beings sustaining burns wh

43、en 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 skin (approximately 10

44、% 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 can be more serious

45、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 even in the absence of b

46、urning. 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 to products used in an

47、y 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. DIN EN ISO 13732-1:20
