Foreword to EN 343:2003+A1:2007+AC:2009 4 Introduction In this European Standard the measured p
22、roperties of materials and seams of protective clothing and their subsequent classification are intended to ensure an adequate protection level. Water proofness and water vapour resistance are the essential properties to be tested and marked on the label. Water proofness is the most important proper
23、ty and it is measured on material of the outer garment layer. Tests are made on new and pretreated fabric samples and on parts with seams. Some waterproof materials are impermeable to water vapour transmission. However other materials on the market combine water proofness with water vapour permeabil
24、ity. This property expressed by low water vapour resistance enhances sweat evaporation and significantly contribute to body cooling. This is valuable, because it contributes to better comfort and less physiological strain and prolongs the wearing time in certain climatic conditions (see annex A). DI

The testing of rain proofness o
26、f ready made garments is excluded in this standard at this time because a separate test method for such a property is currently being prepared. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are

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.
