14、TIONAL ELECTROTECHNICAL COMMISSION MATTING OF INSULATING MATERIAL FOR ELECTRICAL PURPOSES FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the I
15、EC is to promote international cooperation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committ
16、ee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in
17、accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on which all the National Committees having a special interest therein are represented, express, as nearly as poss
18、ible, an international consensus of opinion on the subjects dealt with. 3) They have the form of recommendations for international use published in the form of standards, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international
19、unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the lat
20、ter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. International Standard IEC 1111 has been prepared by IEC technical committee 78: Tools for live working. The text of thi
21、s standard is based on the following documents: DISReport on Voting 78(CO)6378(CO)67 Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This standard was also submitted to parallel voting in CENELEC. Annexes A, B, C and
22、 D form an integral part of this standard. Annexes E, F and G are for information only.

47、p and finish Matting shall be free on both 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,
48、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 either surface of the matting due to imperfections on forms or moulds or other imper
49、fections inherent to the manufacturing process. These irregularities appear as mould marks that look like cuts even though they are actually a raised ridge of elastomer, indentations, or protuberances that are acceptable provided that: a) the thickness at any irregularity conforms to the thickness requirements. Surface design to improve slip resistance shall not be considered as irregularities; b) the indentations, protuberances or mould marks tend
