    22、ING MATERIALS USED UNDER SEVERE AMBIENT CONDITIONS TEST METHODS FOR EVALUATING RESISTANCE TO TRACKING AND EROSION FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committe

    23、es). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available

    24、 Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organi

    25、zations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical ma

    26、tters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC Natio

    27、nal Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, I

    28、EC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itse

    29、lf does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that t

    30、hey have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature

    31、 whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced p

    32、ublications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International

    33、 Standard IEC 60587 has been prepared by IEC technical committee 112: Evaluation and qualification of electrical insulating materials and systems. This third edition cancels and replaces the second edition, published in 1984, and constitutes a technical revision. The main changes from the previous e

    34、dition are as follows: experience has indicated the need for improved description of the experimental method. For the preparation of the test specimens abrasion is recommended only if necessary. The ventilation of the test chamber is described in detail. For specimens of soft elastomeric materials a

    35、 mounting support is described. The maximum depth of erosion has to be reported in the classification. This bilingual version, published in 2009-11, corresponds to the English version. 4 60587 IEC:2007 The text of this standard is based on the following documents: FDIS Report on voting 112/56/FDIS 1

    36、12/61/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. The French version of this standard has not been voted upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committe

    37、e has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised

    38、 edition, or amended. 60587 IEC:2007 5 ELECTRICAL INSULATING MATERIALS USED UNDER SEVERE AMBIENT CONDITIONS TEST METHODS FOR EVALUATING RESISTANCE TO TRACKING AND EROSION 1 Scope This International standard describes two test methods for the evaluation of electrical insulating materials for use unde

    39、r severe ambient conditions at power frequencies (45 Hz to 65 Hz) by measurement of the resistance to tracking and erosion, using a liquid contaminant and inclined plane specimens. The two methods are as follows: Method 1: constant tracking voltage; Method 2: stepwise tracking voltage. NOTE 1 Method

    40、 1 is the most widely used method as there is less need for continual inspection. NOTE 2 The test conditions are designed to accelerate the production of the effects, but do not reproduce all the conditions encountered in service. 2 Terms and definitions For the purposes of this document, the follow

    41、ing terms and definitions apply. 2.1 track partially conducting path created by localized deterioration on the surface of an insulating material 2.2 tracking progressive degradation of the surface of a solid insulating material by local discharges to form conducting or partially conducting paths NOT

    42、E Tracking usually occurs due to surface contamination.

    43、al Vocabulary Chapter 212: Insulating solids, liquids and gases 6 60587 IEC:2007 3 Test specimens 3.1 Dimensions Flat specimens with a size of at least 50 mm X 120 mm shall be used. The preferred thickness shall be 6 mm. Other thicknesses may be used, but must be mentioned in the test report. The sp

    44、ecimens shall be drilled as shown in Figure 1, to attach the electrodes. 120 (at least) 50 (at least) 95 10 5 25 Reference marks IEC 672/07 Dimensions in millimetres Figure 1 Test specimen with holes for fixing electrodes 3.2 Preparation The specimens shall be washed with a suitable solvent (e.g. is

    45、opropyl alcohol) to remove leftovers such as fat from handling. After that the specimens shall be rinsed with distilled water. The cleaned specimens shall be mounted carefully to avoid contamination. If the contaminant does not wet the surface evenly within the observation time mentioned in 5.1, the

    46、 surface of the specimens can be slightly abraded. The abrasion should be done with a fine (U.S. grade (CAMI): 400 mesh; European grade (FEPA): P800) aluminium-oxide- or zirconia-aluminia-abrasive under water until the whole surface wets and appears uniformly matt when dry. When abraded the specimen

    47、 shall be cleaned another time with distilled water. Abrasion has to be mentioned in the test report. Specimens used for criterion B (see 5.4) shall have reference marks on both edges, 25 mm above the lower electrode (see Figures 1 and 7). 4 Apparatus 4.1 Electrical apparatus A schematic circuit is

    48、given in Figure 2. As the test will be carried out at high voltages, it is obviously necessary to use an earthed safety enclosure. The circuit comprises: 60587 IEC:2007 7 A 45 Hz to 65 Hz power supply with an output voltage stabilized to 5 % which can be varied up to about 6 kV with a rated current

    49、not less than 0,1 A for each specimen. Preferred test voltages are 2,5 kV, 3,5 kV and 4,5 kV, for method 1.
