The object of the 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, the IEC publishes International Standards. 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 organizations liaising with the IEC also participate in this preparation. The 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 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 interested National Committees. 3)The documents produced have the form of recommendations for international use and are published in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4)In order to promote international 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 latter. 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. 6)Attention is drawn to the possibility that some of the elements of this Technical Report may be the subject of patent rights. 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. However, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC 61010-3, which is a technical report, has been prepared by technical committee 66: Safety of measuring, control, and laboratory equipment. The text of this technical report is based on the following documents: Enquiry draftReport on voting 66/275/DTR66/302/RVC 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 publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This report is a Technical Report and is of a purely informative nature and is therefore by itself not to be regarded as an International Standard. 4 TR 61010-3 IEC:2003(E) The committee has decided that the contents of this publication will remain unchanged until 2008. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition; amended. TR 61010-3 IEC:2003(E) 5 SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT FOR MEASUREMENT, CONTROL, AND LABORATORY USE Part 3: Protocol for the preparation of conformity verification reports for the IEC 61010 2nd edition series 1 Scope This part of IEC 61010 is a technical report, which provides a test protocol to assist 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 General Conformity verification reports (CVRs) should only be used with the appropriate standards. Individual report layouts reflecting the referenced documents are presented for each part of the IEC 61010 series in the form of a check list, together with the 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 CVR, it is essential that test personnel refer to the appropriate standard(s). Where any doubts arise, the requirements of standards take preference over the text of CVRs. The part 2 standards indicate in their forewords which amendments (if any) are applicable to IEC 61010-1: 2001 2nd edition. Care should be taken to ensure that any potentially destructive testing is performed last in the sequence of testing, 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 IEC 61010-1: 2001 is given in Annex A for a report on a specific product. 3 Applicability of conformity verification reports 3.1 CVR for IEC 61010-1: 2001, 2nd edition IEC 61010-3-1: 2003 for: a) IEC 61010-1: 2001 or b) IEC 61010-1: 2001 + amendment 1: (in preparation) 3.2 CVRs for part 2 standards with cross-references to IEC 61010-1: 2001 - 2nd edition a) IEC 61010-3-010 for IEC 61010-2-010.

The documents e) to n), if applicable, 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) data sheets, test results or certification details for cathode-ray tubes; k) constructional drawings and specifications for transformers including winding and insulation details; l) test results for abnormal operation and fault conditions; m) layout of printed wiring boards with primary and secondary hazardous voltages showing all working voltages on the tracks; n) circuit diagrams, and assembly drawings of printed wiring boards. 5 Completion of the report a) If additional information is required for any part of the report, it should be included on a separate sheet. b) Clause 6 Protection against electric shock Block diagram of a system. Where applicable, the table in Form A.5 should be completed and a block diagram included (where possible) to assist analysis of the product. See Figure 1 and Table 1 as examples of a block diagram and of a completed table. The letters A, B, etc., indicate points between which dielectric strength tests, or measurements of CREEPAGE DISTANCE or CLEARANCE, should be made.
