BS EN 61298-4:2008EN 61298-4:2008 - 2 - Foreword The text of document 65B/688/FDIS, future edition 2 of IEC 61298-4, prepared by SC 65B, Devices any particular method or procedure, not covered by this standard, should be developed and specified in the new standard in accordance with the crit

13、eria, as far as they are applicable, stated in this standard; any conceptual or significant deviation from the content of this standard, should be clearly identified and justified if introduced in a new standard.

14、ETHODS 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 functional and performance characteristics of process measurement and control devices. The tests are a

15、pplicable 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 digital devices. For devices that require special tests, this standard should be used, together

16、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 results obtained. It specifies the major items which should be included in the evaluation report, but

17、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 following referenced documents are indispensable for the application of this document. For dated re

18、ferences, 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 Vocabulary (IEV) IEC 60050-300, International Electrotechnical Vocabulary (IEV) Electrical and ele

If a second

20、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. No particular method of binding together the pages of the report is specified. This is left to t

21、he discretion of the test laboratory issuing the report. BS EN 61298-4:200861298-4 IEC:2008 7 3.3 Page numbering 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 numbe

22、red sequentially. Page numbers shall be shown in the format “Page x of y“ , where x is the specific page 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 t

23、he page numbering sequence. 3.4 Draft and final reports It is sometimes desirable and advantageous to issue 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, bu

24、t need not be presented or bound exactly as the subsequent final report. 3.5 Abridged reports At the discretion 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 includ

25、e at least the introduction, major findings, and manufacturers comments, exactly as presented in the full 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

26、 give all the following information: report number; date of issue; manufacturers name, and country of manufacture; 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 evaluation

27、s. The manufacturers name shall be the full name of the manufacturer company at the time when the instrument 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 wa

28、s finally assembled into a complete instrument. This may not be the same as the country from which the instrument 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 d

29、etails and size or range. BS EN 61298-4:2008 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 Clau

30、se 4, 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 th

31、is page 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 pa

32、ge 1 of 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

33、size of 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 foll

34、owing 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 i

35、ntroduction 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. BS EN 61298-4:200861298-4 IEC:2008 9 Paragraph 1 “This report describes the evaluation of a. (instr

36、ument and model) manufactured by. (manufacturers name). The instrument was a. (standard production/prototype/etc. model) manufactured in. (country of manufacture)“. Paragraph 2 “The instrument was evaluated to a test programme drawn up by. (laboratory or sponsor) based on. (quote briefly the main re

Give also, as appropriate, input span, output span, range, and whether adjustable or not. Paragraph 4 The manufacturers quoted indication of general perform

38、ance. Paragraph 5 A brief description of the principle of operation. Paragraph 6 Primary application, intended environment, ancillary equipment, options available, special features, etc., power supply required, safety status (whether approved or not for use in flammable atmospheres). Paragraph 7 “Th

39、e equipment was delivered on. and was evaluated over a period of. weeks/months from. (commencement date) until. (date of completion of tests).“ If this period is unduly protracted the reason(s) for the delays should be briefly stated. 8 Major findings and comments Two sentences similar to the follow

40、ing examples shall appear immediately under the title. “These findings are summarized here for ready reference, and to give an overview of the evaluation. For a complete assessment of the instrument, the report shall be read and considered as a whole.“ “All errors and changes are expressed as a perc

41、entage of output span unless otherwise stated.“ This clause should summarize and comment on the most significant findings from the evaluation. The comments should be brief and concise, and, for example, may be grouped under the following headings. Manufacturers performance specifications Briefly com

42、ment if the manufacturers specifications are not comprehensive. Satisfactory performance features State all the tests in which the results were satisfactory and within the manufacturers relevant specification. If required, a summary of the results may be given.
