The work of preparing International Standards is normally carried out through ISO technical comm
21、ittees. 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
22、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 Internation
23、al 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 th
24、e 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, Subc
25、ommittee SC 5, Ergonomics of the physical environment, in accordance with the Agreement on technical cooperation 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 respon
26、ses to contact with surfaces: Part 1: Hot surfaces Part 2: Human contact with surfaces at moderate temperature Technical Specification Part 3: Cold surfaces BS 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 surfac
27、e, 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 structure of the surface, and the sensitivity of the human being who com
28、es 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 are listed. This part of ISO 13732 contains a collection of temperat
29、ure 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 assessment procedure (Clause 5). A further application of the data m
30、ay 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 surface of a hot product. Guidance on how to select reasonable tempe
31、rature 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 ki
32、nd 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 will be different if the object is touched intentionally than if it
33、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 safety level. For intentional touching the minimum applicable contact
34、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 B. The ergonomics data provided in this part of ISO 13732 are mai
35、nly 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 based on scientific research but are deduced by extrapolation of the k
36、nown 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 are not sufficient scientific data available on the effects of di
37、scomfort 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 par
38、t 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 with liquids or gases. NOTE With the exception of water there are no
39、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.

40、 environment Methods for the assessment of human responses to contact with surfaces Part 1: Hot surfaces 1 Scope 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 t
41、he risks of burning, when humans could or might touch hot surfaces with their unprotected skin. This part of 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 l
42、imit values can be specified in specific product standards or in regulations in order to prevent human beings 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 temper
43、ature is essentially maintained during the contact (see 4.1). It 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. Neither does it apply to skin contact of more than 10 % of the head or contact which could
44、 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 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 l
45、oss; heating of a large proportion of the head or whole body that could lead to unacceptable heat strain even 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 simplifi
46、cation, it mentions only products; nevertheless, it applies to all other objects as well. It is applicable to 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
47、 people with physical disabilities. It does not provide data for the protection against discomfort or pain.
