EN 14605:2005 (E) 3 Foreword This document (EN 14605:2005) 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of an identical text or by endorsement, at the latest by September 2005, and conflicting national standards shall be withdrawn at the latest by September 2005. This document supersedes EN 465:1995, EN 466:1995 and EN 467:1995. 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 Directive(s), see informative Annex ZA, which is an integral part of this document. This document includes a Bibliography. 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.



EN 14605:2005 (E) 4 1 Scope This document specifies the minimum requirements for the following types of limited use and reusable chemical protective clothing:  Full-body protective clothing with liquid-tight connections between different parts of the clothing (Type 3: liquid-tight clothing) and, if applicable, with liquid-tight connections to component parts, such as hoods, gloves, boots, visors or respiratory protective equipment, which may be specified in other European Standards.
Examples of such clothing are one-piece coveralls or two-piece suits, with or without hood or visors, with or without boot-socks or over-boots, with or without gloves;  Full-body protective clothing with spray-tight connections between different parts of the clothing (Type 4: spray-tight clothing) and, if applicable, spray-tight connections to component parts, such as hoods, gloves, boots, visors or respiratory protective equipment, which may be specified in other European Standards.
Examples of such clothing are one-piece coveralls or two-piece suits, with or without hood or visors, with or without boot-socks or over-boots, with or without gloves;  Partial body protection garments offering protection to specific parts of the body against permeation of chemical liquids. Examples of such garments are e.g. laboratory coats, jackets, trousers, aprons, sleeves, hoods (not air-supplied) etc. As partial body protection leaves some parts of the body unprotected this document specifies only the performance requirements for the clothing material and the seams. NOTE Partial body chemical protective garments which offer only protection against penetration of chemical liquids are within the scope of EN 13034 (Type PB [6] clothing). 2 Normative references The following referenced documents are indispensable for the application of this document.

EN 14605:2005 (E) 5 3 Terms and definitions For the purposes of this document, the terms and definitions given in CEN ISO/TR 11610:2004 apply. 4 Requirements 4.1 Materials Chemical protective clothing materials shall be tested according to the requirements of Table 1 and in accordance with the test methods specified in EN 14325. A performance level of at least 1 shall be obtained for all requirements. Chemical protective clothing materials shall not be known to cause skin irritation or have any adverse effect to health (see also EN 340:2003, 4.2). Prior to testing, all chemical protective clothing materials shall be cleaned, if the manufacturer's instructions indicate that cleaning is allowed. Manufacturer’s instructions with regard to number of cleaning cycles, cleaning procedures and possible reapplication of treatments shall be observed. If no maximum number of cleaning cycles is indicated, materials shall undergo five cycles. All test specimens shall be conditioned at (20 ± 2) °C and (65 ± 5) % relative humidity for at least 24 h and testing shall start within 5 min after removing the specimen from the conditioning atmosphere. Table 1 — Test requirements for Type 3, Type 4, Type PB [3] and Type PB [4] clothing Clause in
EN 14325:2003 Performance requirement 4.4 abrasion resistance 4.5 flex cracking resistance 4.6 a flex cracking resistance at –30 °C 4.7 tear resistance (trapezoidal) 4.9 tensile strength 4.10 puncture resistance 4.11 resistance to permeation of liquids 4.14 resistance to ignition a Only applicable to clothing intended for use at very low temperatures.
NOTE 1 Chemical protective clothing material, for which a test method in Table 1 does not provide a clear measurement end-point, should be marked "not applicable" in the test report and in the instructions for use. The reason why the test could not be completed should be indicated, e.g. where the elasticity of the specimen prevents to determine an end-point in the puncture resistance test. NOTE 2 Materials should be as light and as flexible as possible in order to ensure wearer comfort as well as providing effective protection. Material properties are only one element for the determination of wearer comfort of protective clothing. Design features of the clothing may even have a more important influence on wearer comfort than material properties.



EN 14605:2005 (E) 6 4.2 Seams, joins and assemblages Seams, joins and assemblages shall be tested and classified according to the requirements of Table 2 and the corresponding clauses of EN 14325. Table 2 — Requirements for seams, joins and assemblages of Type 3, Type 4, Type PB [3]a and
Type PB [4] clothing Performance requirement Reference resistance to permeation of liquids b EN 14325:2003, 4.11 resistance to penetration by liquids c EN 463 or
EN 468 seam strength EN 14325:2003, 5.5 a Seams, joins and assemblages of Type PB [3] clothing shall be tested to the jet test (EN 463). b Applicable only to seams which are exposed in use. For partial body protection items only seams relevant to the construction shall be considered and a performance level of at least 1 shall be obtained. c To be tested by whole suit tests, i.e. EN 463 (jet test) for Type 3 clothing and EN 468 (high level spray test) for Type 4 clothing.
4.3 Performance requirements for whole suits (Types 3 and 4) 4.3.1 General Chemical protective clothing shall fulfil the relevant requirements of EN 340. The clothing shall be made so that the wearer has freedom of movement and is as comfortable as possible, consistent with the protection afford
