3 Foreword This document 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of an identical text or by endorsement, at the latest by December 2004, and conflicting national standards shall be withdrawn at the latest by December 2004. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements 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 of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom

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 (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 (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 garments 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 European 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 lcler can be determined and used to define temperature ranges (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 and 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 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 incorporated in it by amendment or revision.

5 3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply: 3.1 cool environment environment characterized in general as a possible combination of humidity and wind at temperatures of -5 °C and above 3.2 garment individual component of a clothing ensemble, the wearing of which provides protection to the part of the body that it covers 3.3 ensemble clothing consisting of a two-piece suit or one-piece suit (coverall) or a number of garments covering the body, except head, hands and feet 3.4 thermal lining non-watertight layer providing thermal insulation 3.5 properties of clothing materials or material combinations
3.5.1 thermal resistance (insulation) Rct
temperature difference between the two faces of a material divided by the resultant heat flux per unit area in the direction of the gradient. The dry heat flux may consist of one or more conductive, convective and radiant components. Thermal resistance Rct, expressed in square metres kelvin per watt, is a quantity specific to textile materials or composites which determines the dry heat flux across a given area in response to a steady applied temperature gradient. 3.5.2 water vapour resistance Ret
water vapour pressure difference between the two faces of a material divided by the resultant evaporative heat flux per unit area in the direction of the gradient. The evaporative heat flux may consist of both diffusive and convective components. Water vapour resistance Ret, expressed in square metres pascal per watt, is a quantity specific to textile materials or composites which determines the "latent" evaporative heat flux across a given area in response to a steady applied water vapour pressure gradient. 3.5.3 resistance to water penetration WP hydrostatic pressure supported by a material is a measure of the opposition to the passage of water through the material The value is given in Pa. 3.6 thermal insulation of the protective clothing Depending on the end use of the garment different thermal insulation values apply. 3.6.1
effective thermal insulation Icle
thermal insulation from skin to outer clothing surface under defined conditions measured with a stationary manikin The effective thermal insulation value, Icle, is determined in relation to the naked body surface area. The value is given in m²K/W.

EN 14058: 2004 (E)
6 3.6.2 resultant effective thermal insulation lcler thermal insulation from skin to outer clothing surface under defined conditions measured with a moving manikin The resultant effective thermal insulation value, lcler, is determined in relation to the naked body surface area. The value is given in m²K/W. 3.6.3 insulation required IREQ required resultant thermal insulation calculated on the basis of the thermal parameters of the environment (e. g. air temperature, mean radiant temperature, air velocity, relative humidity) and the body metabolism
NOTE see ISO/TR 11070. 4 Performance requirements 4.1 General The ergonomic requirements of EN 340 shall be applied. 4.2 Thermal resistance, Rct When tested in accordance with 5.1, the thermal resistance Rct of all layers of the garment shall be in accordance with Table 1.
