The proposal was transmitted to the secretariat of CEN/TC 162 with the request to induce the publishing of the draft European Standard. Following the first Preliminary Enquiry of separate standards for Type1 and 2 re-usable protective clothing it was agreed to combine these into a single standard and include limited use clothing. This revision was substantial enough to justify a 2nd Preliminary Enquiry.This document has been prepared under a mandate given to CEN by the European Commission and theEuropean Free Trade Association, and supports the essential requirements of EU Directive 89/686/EEC. For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document. Annexes A, B and C are normative.-,-,-According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.3-,-,-EN 943-1:2002 (E)1ScopeThis European Standard specifies the minimum requirements, test methods, marking and information supplied by the manufacturer for the following ventilated and non-ventilated limited use and re-usable chemical protective suits, including component parts such as gloves and boots which can be specified elsewhere.Type 1 - "gas-tight" chemical protective suitType 1a - "gas-tight" chemical protective suit with a breathable air supply independent of the ambient atmosphere, e.g. a self-contained open-circuit compressed air breathing apparatus, worn inside the chemical protective suit.Type 1b - "gas-tight" chemical protective suit with a breathable air supply, e.g. a self-contained open- circuit compressed air breathing apparatus, worn outside the chemical protective suit.NOTEAs chemical protective suits are used with respiratory devices, special attention should be given to the adequate selection of respiratory protective equipment. The limiting factors for the use of respirator filters (e.g. oxygen deficiency) should be taken into consideration.Type 1c - "gas-tight" chemical protective suit with breathable air providing positive pressure, e.g. air lines.Type 2 -”non-gas tight” chemical protective suit"Non-gas-tight" chemical protective suit with breathable air providing positive pressure. Specifications for total inward leakage test see annex A.Specifications for test methods and performance classification for materials, seams, joins and assemblages see annex B.Specifications for glass paper and glass cloth see annex C.2Normative referencesThis 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.
