3.1 0 formally trained and qualified person competent person possessing the appropriate practical and theoretical knowledge and having adequate skill and experience to enable the person to perform the required periodic testing, interpret the resultant information and from that information determine that the electrical insulating glove is safe to use, and report the importance of any defect found or suspected in relation to the safety and continued use of the electrical insulating glove 3.1 1 gauntlet part of a glove from the wrist to the open part of the glove 3.1 2 lined glove glove with an inside lining of textile attached to the elastomer 3.1 3 long glove electrical insulating glove used to extend the protection to the upper arm Note 1 to entry: The length of the glove does not include protection up to the armpit. [SOURCE: IEC 60743:201 3, 8.1 .5, modified – The whole document is about insulating glove protecting against electric shock so that does not need to be repeated in the term and its definition. The note 1 to entry has been added to clarify the type of protection offered] 3.1 4 mitt glove with multiple fingers enclosed in one covering 3.1 5 nominal voltage of a system suitable approximate value of voltage used to designate or identify a system [SOURCE: IEC 60050-601 :1 985, 601 -01 -21 ] 3.1 6 palm part of glove covering the face of the central inside hand 3.1 7 proof test voltage specified voltage that is applied to a glove for the time defined under specified conditions to assure that the electrical strength of the insulation is above a specified value 3.1 8 withstand test voltage voltage that the glove withstands without disruptive discharge when voltage is applied under specified conditions 3.1 9 wrist narrowest part of the glove between the cuff and the hand
4.3.4 Workmanship and finish Gloves shall be free on both inner and outer surfaces from harmful physical irregularities that can be detected by thorough test and inspection. Harmful physical irregularities shall be defined as any feature that disrupts the uniform, smooth surface contour, such as pinholes, cracks, blisters, cuts, conductive embedded foreign matter, creases, pinch marks, voids (entrapped air), prominent ripples and prominent mould marks. Non-harmful physical irregularities shall be defined as surface irregularities present on the inner and outer surfaces of the glove due to imperfections on molds and inherent difficulties in the manufacturing process. These irregularities may appear as mould marks that look like cuts even though they are actually a raised ridge of material, indentations, protuberances, embedded foreign matter, or colour splashes that are acceptable provided that: a) the indentations, protuberance or mould marks tend to blend into a smooth slope upon stretching of the material; b) foreign material remains in place when the glove is folded and stretched with the material surrounding it;
4.4 Mechanical, climatic and environmental requirements Gloves shall withstand the mechanical, climatic and environmental stresses specified in this standard. Gloves with one or more special categories (see Table 1 ) shall support any related stresses. 4.5 Electrical requirements Gloves shall be capable of withstanding the corresponding electrical stresses according to its electrical class. 4.6 Marking Each glove which is claimed to comply with the requirements of this standard shall bear a label and/or marking giving the following information:– symbol IEC 6041 7-521 6:2002-1 0 – Suitable for live working; double triangle (see Annex B); NOTE The exact ratio of the height of the figure to the base of the triangle is 1 ,43. For the purpose of convenience, this ratio can be between the values of 1 ,4 and 1 ,5. – number of the relevant IEC standard immediately adjacent to the symbol (IEC 60903); – name, trademark or identification of the manufacturer; – category, if applicable; – size; – class; – month and year of manufacture. Composite gloves shall also be identified with a mechanical symbol (hammer), adjacent to the double triangle (see Figure 3). The length of the hammer (x) shall be equal to the length of one side of the triangles.
