BS EN 16350:2014EN 16350:2014 (E) 4 1 Scope This Europe

16、an Standard provides additional requirements for protective gloves that are worn in areas where flammable or explosive areas exist or might be present (see IEC 60079-32-1). It specifies a test method and requirements for performance, marking and information for electrostatic dissipative protective g

17、loves to minimize explosion risks. This European Standard does not cover: protection of electronic devices; protection against mains voltages; insulative protective gloves for live working (EN 60903); protective gloves for welders (EN 12477). The requirements may not be sufficient in oxygen enriched

18、 flammable atmospheres. This European Standard should be used with the specific standards applicable to the risks for which the glove is designed. NOTE The electrostatic dissipative protective gloves are effective only if the wearer is earthed through a resistance lower than108. 2 Normative referenc

19、es The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

26、tical resistance: Rv 1,0 108. 4.2.2 Design requirements 4.2.2.1 Protective gloves shall be produced without electrically conductive connections (e.g. by metal rivets). 4.2.2.2 External thin attachments, such as labels or reflective stripes shall be permanently attached around all edges. 4.2.2.3 Adju

27、stment systems such as hook and loop systems shall not be used. 5 Test methods 5.1 Preparation of test specimens Testing shall be conducted on unused gloves. If care instructions are provided, the test shall be performed also after the recommended number of cleaning cycles. 5.2 Specimens 5.2.1 One s

28、pecimen sized 10 cm x 10 cm shall be taken from each palm of 5 different gloves of the same type. 5.2.2 If this size of specimen is not possible, then a smaller specimen suitable for the adjusted test apparatus specified in 5.4.2 shall be used. It shall be mentioned in the test report. BS EN 16350:2

29、014EN 16350:2014 (E) 6 5.2.3 The specimens shall be free of any seam. 5.2.4 Multiple layers which are unbonded to each other shall be tested together. 5.2.5 If palm, back of the hand or cuff consist of different materials or material combinations, five specimens shall be taken of each. 5.2.6 The spe

30、cimens shall be handled only at the edges. 5.3 Conditioning and testing atmosphere The electrostatic properties may vary with the moisture content of the material. The specimens shall be conditioned prior to testing for at least 48h. The conditioning atmosphere shall be the same as the test atmosphe
