15、 Uncontrolled Copy, (c) BSI 6 61298-4 IEC:2008 PROCESS MEASUREMENT AND CONTROL DEVICES GENERAL METHODS AND PROCEDURES FOR EVALUATING PERFORMANCE Part 4: Evaluation report content 1 Scope This part of IEC 61298 specifies general methods and procedures for conducting tests, and reporting on the functi

16、onal and performance characteristics of process measurement and control devices. The tests are applicable to any such devices characterized by their own specific input and output variables, and by the specific relationship (transfer function) between the inputs and outputs, and include analogue and

17、digital devices. For devices that require special tests, this standard should be used, together with any product specific standard specifying special tests. This standard specifies the content of the written report on the evaluation or tests on a process measurement or control device, and the result

18、s obtained. It specifies the major items which should be included in the evaluation report, but it does not specify the exact format in which the contents should be presented. (This is left to the discretion of the test laboratory which prepares and issues the report.) 2 Normative references The fol

19、lowing referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60050 (all parts), International Electrotechnical Vo

21、s 3.1 Report coverage One report shall refer to one evaluation on a subject device. If a second evaluation is made on the same device, then a separately numbered report shall be issued. 3.2 Report binding Each copy of the report shall be bound with covers, so that the pages cannot become separated.

22、No particular method of binding together the pages of the report is specified. This is left to the discretion of the test laboratory issuing the report. BS EN 61298-4:2008Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 21/01/2010 02:26, Uncontrolled Copy, (c) BSI61298-4 IEC:2008 7 3.3 Page nu

23、mbering Each page of the report shall be identified with a unique, sequential page number. It is a convention to regard the first page of text in the report as page 1, with subsequent pages numbered sequentially. Page numbers shall be shown in the format “Page x of y“ , where x is the specific page

24、number and y is the number of the last page of the report. The report number should be given also. If a separate title page is placed at the front of the report, this is not usually included in the page numbering sequence. 3.4 Draft and final reports It is sometimes desirable and advantageous to iss

25、ue a preliminary, draft version of an evaluation report for comment prior to the issue of a formal, final version of the report. Each page of draft reports shall be clearly identified as such, but need not be presented or bound exactly as the subsequent final report. 3.5 Abridged reports At the disc

26、retion of the issuing authority, or the test laboratory, an abridged version of the report may be issued, complementary to the full report. If an abridged report is issued, it shall always include at least the introduction, major findings, and manufacturers comments, exactly as presented in the full

27、 report. 3.6 Units SI units should be used throughout the report. When other units need to be used, the SI equivalent should be given in brackets alongside. 4 Report title Each report title shall give all the following information: report number; date of issue; manufacturers name, and country of man

28、ufacture; instrument type; model name or number. The report number shall be a unique number, one of a series, which refers only to one report of one evaluation, or possibly a series of evaluations. The manufacturers name shall be the full name of the manufacturer company at the time when the instrum

29、ent was supplied for evaluation. Any changes in name during the period of evaluation should be indicated in the introduction of the report. The country of manufacture shall be where the device was finally assembled into a complete instrument. This may not be the same as the country from which the in

30、strument was supplied for evaluation. The correct status may need to be confirmed by the author of the report. The instrument type shall be a brief, general description of function, application details and size or range. BS EN 61298-4:2008Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 21/01/

31、2010 02:26, Uncontrolled Copy, (c) BSI 8 61298-4 IEC:2008 Any further details about the equipment itself, or the range of tests applied, should be described in the introduction of the report. 5 Preliminary pages 5.1 Title page This page shall include the full report title, as specified in Clause 4,

32、plus the name of the test laboratory and the names(s) of the author(s). The report shall identify the sponsor of the evaluation and any information regarding the use of any proprietary information contained. Additional information about the laboratory compiling the report may be provided on this pag

33、e at the discretion of the laboratory. This page is not usually numbered. 5.2 Contents page This page is not included in the sequence of page numbers for the text of the report. 5.3 Photograph of the equipment tested This shall always be shown in Figure 1. It should preferably appear facing page 1 o

34、f the report. It should be a photograph of the equipment actually tested with the covers on, three-quarter front view, if this is possible. If a photograph of the same type of equipment, provided by the manufacturer, is used, this should be stated. A scale, or some other means to indicate the size o

35、f the equipment, shall be included in Figure 1. 6 First page of report This page shall always contain the heading to the report and the introduction. It may also contain the first part of the “Major findings and comments“ clause. The heading to the report shall always contain at least the following

36、information: title of the report (including manufacturers name, type of device and model); author(s) names(s) and professional qualifications; name of evaluation laboratory; project number; sponsor(s) of the project; report number; date (month and year) of issue of the final report. 7 Report introdu

37、ction The introduction should not cover more than one page. The paragraphs indicated below should be included in this clause, using the standard wording shown in italic print, wherever relevant.
