BS EN 14605:2005+A1:2009EN 14605:2005+A1:2009 (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 connect
22、ions 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 a
23、re 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-tig
24、ht 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-bo
25、ots, 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 l
26、eaves 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 c
27、lothing). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

33、 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 test
34、ing, all chemical protective clothing materials shall be cleaned, if the manufacturers instructions indicate that cleaning is allowed. Manufacturers instructions with regard to number of cleaning cycles, cleaning procedures and possible reapplication of treatments shall be observed. If no maximum nu
35、mber 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.

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
38、 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 co
39、mfort 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. BS EN 14605:2005+A1:2009EN 14

41、of Table 2 and the corresponding clauses of EN 14325.

For partial body protection items only seams relevant to the construction shal

44、l 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 afforded by the garment, as can be verified by the “seven movements“ test, describe
45、d in 4.3.4.1. NOTE 1 Wearer comfort can be judged in wear trials of the suit with test persons experienced in the type of work and environments for which the suits are intended as protective clothing. Chemical protective clothing Type 3 and Type 4 shall fulfil the requirements specified in 4.3.4 (Ta
46、ble 3), when combined with additional protective equipment, i.e. for protection of hands, feet, face, head and/or respiratory tract, according to the manufacturers instructions and when tested as a complete suit. The requirements of this clause apply to the garment as a whole including component par
47、ts (e.g. gloves, boots, hoods or respirators) that are not integral to the garment. The joins and assemblages attaching these components are included within the scope of this document, whereas criteria for the components are given in other European Standards. NOTE 2 Partial body protection covers on
48、ly specific areas of the body, leaving others exposed to the hazard. Because of this only limited testing of this type of clothing is appropriate and this product standard is defined accordingly. 4.3.2 Pre-conditioning Prior to testing, the chemical protective clothing shall be cleaned, if the manuf
49、acturers instructions indicate that cleaning is allowed. Manufacturers 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, the clothing shall undergo five cleaning cycles. BS EN 14605:2005+A1:2009EN 14605:2005+A1:2009 (E) 7 4.3.3 Conditioning All chemical pr
