16、ocument EN 14058:2004 has been prepared by Technical Committee CEN/TC 162 “Protective clothing including hand and arm protection and lifejackets”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical t

This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential require

18、ments of EU Directive 89/686/EEC. For relationship with EU Directives, see informative Annex ZA, which is an integral part of this document. Annex A and annex C are normative. Annex B and annex D are informative. According to the CEN/CENELEC Internal Regulations, the national standards organizations

20、Spain, Sweden, Switzerland and United Kingdom EN 14058: 2004 (E) 4 Introduction In many cases single garments are placed on the market to protect against local body cooling (for ensembles see EN 342). These garments can be e. g. waistcoats, jackets, coats or trousers and/or separable thermal linings

21、 (see Annex D). They can provide a certain degree of protection to cool environment for a certain length of time, depending e. g. on the personal constitution and activity, the accompanying clothing and the environmental features (wind speed, temperature, humidity). The more dangerous the situation

22、(e. g. low effective temperature, long exposure duration, no help nearby) the more important it is to assess the cold protection properties of the garment (see annex B) especially if the user cannot safely identify the risk at low temperature in an appropriate time. At moderate low temperatures garm

23、ents against local body cooling are not only used for outdoor activities e. g. in construction industry but can be used for indoor activities e. g. in food processing industry. In these cases garments often do not need to be made of watertight or air impermeable materials. Therefore, in this Europea

24、n Standard, these requirements are optional. Requirements for thermal insulation of the whole human body in a specific environment can be assessed on the basis of ISO/TR 11079. By this method the resultant effective thermal insulation value l clercan be determined and used to define temperature rang

25、es (see Tables B.1 and B.2). Therefore the protective value of a clothing ensemble is evaluated by comparing its measured insulation value and the calculated required insulation value (IREQ). This comparison is the basis of Tables B.1 and B.2. 1 Scope This European Standard specifies requirements an

26、d test methods for the performance of single garments for protection against cooling of the body in cool environment. It does not include specific requirements for headwear or footwear or gloves to prevent local cooling. 2 Normative references This European Standard incorporates by dated or undated

27、reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when inco

In this case the water vapour resistance R etof all layers of the garment shall be less than 55 m 2Pa/W. 4.6 Thermal insulation, I cleand I cler(optional) The resultant effective thermal insulation l clershall have a mini

46、mum value of 0,170 m 2 K/W or the effective thermal insulation l cleshall have a minimum value of 0,190 m 2 K/W when measured in accordance with 5.5. Thermal insulation of a garment is assessed on the basis of measured insulation values for a complete ensemble of which a garment is only one part. Pe

47、rformance of a garment in terms of preserving heat balance at normal body temperature also depends on internal body heat production. Therefore the protective value of a garment is evaluated by comparing its measured insulation value and the calculated required insulation value (IREQ). This compariso
