23、ii Foreword ISO (the International Organization 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
24、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 International Electrotechnical Commission (IEC) on all matt
25、ers 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 International Standards adopted by the technical committees are circul
26、ated 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 the subject of patent rights. ISO shall not be held responsib
27、le for identifying any or all such patent rights. ISO 13732-3 was prepared by the European Committee for Standardization (CEN) in collaboration with Technical Committee ISO/TC 159, Ergonomics, Subcommittee SC 5, Ergonomics of the physical environment, in accordance with the Agreement on technical co
28、operation between ISO and CEN (Vienna Agreement). Throughout the text of this document, read “.this European Standard.” to mean “.this International Standard.”.

38、 Copy: sheffieldun sheffieldun, na, Sat Nov 18 01:51:28 GMT+00:00 2006, Uncontrolled Copy, (c) BSI vi Introduction This European Standard is a type B standard as stated in EN ISO 12100. The provisions of this document may be supplemented or modified by a type C standard. NOTE For machines which are
39、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 precedence over the provisions of this type B standard. Working with unprotected hands is often inevitable in the cold operation
40、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 frostbite. In addition repeated cold exposures with severe cooling of the skin may induce non-freezing cold injury (possible da
41、mage 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 of contacting cold surfaces so far. Assessment of contact cooling is thus considered necessary. To assess the risk of the c
42、old 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; temperature of the cold surface and ambience; duration of contact between the skin and the surface; characteristics of hand/finge
43、r 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 at various cold temperatures. Thus, the contact time for the critical contact temperature limits on cold surfaces were emp
44、irically correlated with the major factors such as thermal penetration coefficient and surface temperature of the material, respectively. The statistically non-linear models (empirical models) based on the database of lower quartile (75 % protected) are able to estimate the finger/hand contact cooli
45、ng 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 fingers and an artificial finger. It outlines a guideline document for the specification of safe time limits of hand/finger con
46、tact with various cold surfaces. EN ISO 13732-3:2005 Licensed Copy: sheffieldun sheffieldun, na, Sat Nov 18 01:51:28 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 1 1 Scope This European Standard describes methods for the assessment of the risk of cold injury and other adverse effects when a cold surfa
47、ce 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 temperature limit values are required. The data of this standard wil
48、l 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
49、 of applications are given in Annex B. 2 Normative references The following referenced documents are indispensable for the application of this document.
