The object of the IEC is
12、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, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee in
13、terested 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 accord
14、ance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all
15、interested National Committees. 3) The documents produced have the form of recommendations for international use and are 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 unification, I
16、EC 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 latter. 5) The IE
17、C 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. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights.
18、 The IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical report of one of the following types:
19、type 1, when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts; type 2, when the subject is still under technical development or where for any other reason there is the future but not immediate possibility of an agreement on an Interna
20、tional Standard; type 3, when a technical committee has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art”. Technical reports of types1and2are subject to review within three years of publication to decide whether they
21、 can be transformed into International Standards. Technical reports of type3do not necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful. IEC 61010-3, which is a technical report of type3, has been prepared by IEC technical committee66: Safety of
22、measuring, control, and laboratory equipment. The text of this technical report is based on the following documents: Full information on the voting for the approval of this technical report can be found in the report on voting indicated in the above table. This report is a Technical Report of type3a
23、nd is of a purely informative nature. It is not to be regarded as an International Standard. Committee draft Report on voting 66/144/CDV 66/164/RVDiv blankBSIEC61010-3:1997 BSI 04-2000 1 1 Scope This part of IEC61010 is a technical report type3, which provides a test protocol for testhouses and othe
24、r users to assist them with determining and recording verification of conformity of the equipment under test with the reference documents identified on the front cover of the appropriate report. 2 List of conformity verification reports The following conformity verification reports should be used wi
25、th the appropriate standard(s). These part2standards indicate in their forewords which amendments to IEC61010-1 are applicable. Requirements which apply only to amendment2to IEC61010-1 are indicated by “(AM2)” in the first column. Requirements deleted by amendment2to IEC61010-1 are indicated by “(AM
26、1 only)” in the second column. a) IEC61010-3-1 for: 1) IEC 61010-1:1990 + amendment 1:1992; or 2) IEC 61010-1:1990 + amendment 1:1992 + amendment 2:1995; b) IEC 61010-3-010 for IEC61010-2-010:1992 + amendment1:1996; c) IEC 61010-3-010 for IEC61010-2-020:1992 + amendment1:1996; d) IEC 61010-3-031 for

Individual report layouts reflecting the referenced documents are presented for each part of the IEC61010ser
29、ies in the form of a checklist together with forms (where required) for reflecting the results of tests. Key words or phrases of the appropriate standard(s) are mainly used, but in order to understand the full details of the requirements to be met when using a conformity verification report, it is e
30、ssential that test personnel refer to the approriate standards. Where any doubts arise, the requirements of standards take precedence over the text of conformity verification reports. Care should be taken to ensure that any potentially destructive testing is performed last in the sequence of testing
31、, as determined by the tester. Clauses or subclauses which are not applicable need not be included in the prepared report, provided that these omissions are indicated in the contents list of the report. An example of a contents list based on IEC61010-1 is given in Annex A for a report on a specific
32、product. 3 Documents The documents a) to d) together with any others required by the standard should be reviewed and listed in the report: a) general description of the equipment tested; b) OPERATOR instructions; c) installation instruction; d) service instructions. The documents e) to n), if applic
33、able, should also be listed in the report: e) component data sheets and certification details; f) wire data sheets; g) flammability test results or data sheets; h) enclosure flammability test results and/or material data sheets; i) comparative tracking indices of printed wiring board materials; j) d
34、ata sheets, test results or certification details for cathode-ray tubes; k) constructional drawings and specifications for transformers including winding and insulation details;BSIEC61010-3:1997 2 BSI 04-2000 l) test results for abnormal operation and fault conditions; m) layout of printed wiring bo
