DIN EN 1149-5:2008-03 EN 1149-5:2008 (E) 4 Introduction This European Standard is part of a series
17、of standards for test methods and requirements for electrostatic properties of protective clothing. Different parts are necessary, because of the various fields of application and materials. EN 1149 consists of the following parts, under the general title “Protective clothing Electrostatic propertie
18、s“: Part 1: Test method for measurement of surface resistivity; Part 2: Test method for measurement of the electrical resistance through a material (vertical resistance); Part 3: Test methods for measurement of charge decay; Part 4: Garment test (under development); Part 5: Material performance and
19、design requirements. A complete garment test is under study. As long as such a test is not available, it may not be possible to perform a full assessment of the electrostatic properties of protective clothing. This set of standards reflects the current state of knowledge. 1 Scope This European Stand
20、ard specifies material and design requirements for electrostatic dissipative protective clothing, used as part of a total earthed system, to avoid incendiary discharges. The requirements may not be sufficient in oxygen enriched flammable atmospheres. This European Standard is not applicable for prot
21、ection against mains voltages. 2 Normative references The following referenced documents are indispensable for the application of this document.

24、ated fabrics, woven, non-woven, knitwear of which the clothing is made 4 Requirements 4.1 General Electrostatic dissipative protective clothing shall comply with EN 340. 4.2 Electrostatic requirements 4.2.1 Material requirements An electrostatic dissipative material shall meet at least one of the fo
25、llowing requirements: t500,2 tested according to EN 1149-3:2004, test method 2 (induction charging), or a surface resistance of less than or equal to 2,5 x 109, on at least one surface, tested according to EN 1149-1. For a material containing conductive threads in a stripe or grid pattern the spacin
26、g of the conductive threads in one direction shall not exceed 10 mm in any part of the garment. 4.2.2 Design requirements Electrostatic dissipative protective clothing shall be able to permanently cover all non-complying materials during normal use (inclusive bending and movements). If the electrost
27、atic dissipative protective clothing comprises multiple layers, e.g. liner, insulation, outer, the outermost material shall meet the material requirements. Electrostatic dissipative protective clothing shall provide proper fitting with sizing according to EN 340 and allow full body movement with all
28、 closures fastened according to manufacturers instructions. Thin non-dissipative attachments, such as labels, reflective stripes, shall be permanently attached. This shall be done in such a way that separation between the attached elements and the clothing material is avoided. Conductive parts (zipp
29、ers, buttons etc.) are permitted provided they are fully covered by the outermost material when in use.

30、5 - Protection against static electricity 6 Information supplied by the manufacturer The information supplied by the manufacturer shall be according to the specific protective clothing standard respectively to EN 340. In addition, the following warning notices and instructions shall be provided: the
31、 person wearing the electrostatic dissipative protective clothing shall be properly earthed. The resistance between the person and the earth shall be less than 108, e.g. by wearing adequate footwear; electrostatic dissipative protective clothing shall not be open or removed whilst in presence of fla
32、mmable or explosive atmospheres or while handling flammable or explosive substances; an instruction on how the garment shall be correctly fastened and worn; electrostatic dissipative protective clothing shall not be used in oxygen enriched atmospheres without prior approval of the responsible safety
33、 engineer; the electrostatic dissipative performance of the electrostatic dissipative protective clothing can be affected by wear and tear, laundering and possible contamination; electrostatic dissipative protective clothing shall permanently cover all non-complying materials during normal use (incl
34、uding bending and movements). DIN EN 1149-5:2008-03 EN 1149-5:2008 (E) 7 Annex A (informative) Explanation The human body has a low enough volume resistivity to act as a conductor and if insulated from earth it can accumulate electrostatic charge. The charge can be produced by contact electrificatio
35、n, for example by walking across an insulating floor, or by touching charged equipment or materials. It can also arise by induction due to charge on the clothing or adjacent charged objects. A dangerous consequence of the electrostatic potential on charged personnel is that it can be high enough to
36、cause hazardous spark discharges. The control of undesirable static electricity on people is necessary in areas where flammable or explosive atmospheres exist or might be present. In such cases people have to be earthed either directly or through conducting footwear (see EN ISO 20345). In the case w
37、here the wearing of electrostatic dissipative protective clothing has been identified as necessary by risk assessment, clothing complying with the requirements of this European Standard can be suitable. These requirements can be necessary in addition to requirements of protective clothing basically
38、designed for other hazards (e.g. chemicals or fire). Therefore this European Standard should be used in such a way that the requirements supplement those of the specific protective clothing standard. The material and design requirements as specified in this European Standard apply only to electrosta
39、tic dissipative protective clothing worn by persons that are earthed through a resistance lower than 108 (e.g. by wearing appropriate footwear such as safety shoes specified in EN ISO 20345:2004, or by any other suitable means). The requirements of this standard are not intended to be applied for st
40、atic dissipative gloves. For these gloves, the electrical resistance through the material is an important property. The basis for the material and design requirements presented in this European Standard, was obtained through research funded by the European Commission. The research work comprised ign
41、ition testing in hydrogen atmospheres. This research has shown that method 1 of EN 1149-3:2004 is not suited to discriminate between safe and unsafe fabrics. Method 2 has been proven by extensive research to accurately predict incendiary behaviour of fabrics. DIN EN 1149-5:2008-03 EN 1149-5:2008 (E)
