The work of preparing International St
26、andards 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-governmental, in liaison with ISO, also
27、 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. The main task of technical committee
28、s 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 vote. Attention is drawn to the possib

40、O 12100. The provisions of this document may be supplemented or modified by a type C standard. NOTE For machines which are covered by the scope of a type C standard and which have been designed and built according to the provisions of that standard, the provisions of that type C standard take preced
41、ence over the provisions of this type B standard. Working with unprotected hands is often inevitable in the cold operation when a precision task is demanded. However the contact of bare skin with cold surfaces reduces skin temperature, causing acute effects such as discomfort, pain, numbness or fros
42、tbite. In addition repeated cold exposures with severe cooling of the skin may induce non-freezing cold injury (possible damage of nerves or vessels). Although the existing international standards are at hand for the assessment of the cold hazards involved, no standard concerns the special problems
43、of contacting cold surfaces so far. Assessment of contact cooling is thus considered necessary. To assess the risk of the cold injury, it is necessary to know the major factors affecting principally hand/finger cooling on cold surfaces. These factors involve: properties of the object surface; temper
44、ature of the cold surface and ambience; duration of contact between the skin and the surface; characteristics of hand/finger skin and the type and nature of the contact. In practice, these factors are somewhat interacted and complicated. The type of contact material has an impact on the contact time
45、 at various cold temperatures. Thus, the contact time for the critical contact temperature limits on cold surfaces were empirically correlated with the major factors such as thermal penetration coefficient and surface temperature of the material, respectively. The statistically non-linear models (em
46、pirical models) based on the database of lower quartile (75 % protected) are able to estimate the finger/hand contact cooling of a large range of individuals on the cold surfaces. This European Standard is designed to integrate all results obtained from the experimental research with both human fing
47、ers and an artificial finger. It outlines a guideline document for the specification of safe time limits of hand/finger contact with various cold surfaces. BS EN ISO 13732-3:2008ISO 13732-3:2005(E) ISO 2005 All rights reserved 11 Scope This European Standard describes methods for the assessment of t
48、he risk of cold injury and other adverse effects when a cold surface is touched by bare hand/finger skin. This standard provides ergonomics data to establish temperature limit values for cold solid surfaces. The values established can be used in the development of special standards, where surface te
49、mperature limit values are required. The data of this standard will be applicable to all fields where cold solid surfaces cause a risk of acute effects: pain, numbness and frostbite. The data are not limited to the hands but apply to human skin in general. The standard is applicable to the healthy skin of adults (females and males). Considerations on the extension of applications are given in Annex B. 2 Normative references The following referenced documents are indispensable for the application of this document. For
