23、 the performance of their products and by users, or independent testing establishments, to verify the manufacturers performance specifications. The test conditions in this standard, for example the range of ambient temperatures and power supply, represent those, which commonly arise in use. Conseque
24、ntly, the values specified herein shall be used where the manufacturer specifies no other values. The tests specified in this standard are not necessarily sufficient for instruments specifically designed for unusually arduous duties. Conversely, a restricted series of tests may be suitable for instr
25、uments designed to perform within a more limited range of conditions. It will be appreciated that the closest communication should be maintained between the evaluating body and the manufacturer. Note shall be taken of the manufacturers specifications for the instrument, when the test programme is be
26、ing decided, and the manufacturer should be invited to comment on both the test programme and the results. His comments on the results should be included in any report produced by the testing organisation. Page4 EN610031:2004 INDUSTRIAL-PROCESS CONTROL SYSTEMS INSTRUMENTS WITH ANALOGUE INPUTS AND TW
27、O- OR MULTI-STATE OUTPUTS Part 1: Methods of evaluating performance 1 Scope This part of IEC 61003 is applicable to pneumatic and electric industrial-process instruments using measured values that are continuous signals in accordance with IEC 60382, or IEC 60381-1. The other input value (i.e. the se
28、t point value) may be either a mechanical (position, force, etc.) or a standard signal. It should be noted that tests specified herein may be applied to instruments which have other continuous measured values, provided that due allowance is made for such differences. These instruments may be used as
29、 controllers or as switches for alarm and other similar purposes. Instruments with feedback are not covered by this standard. Electronic security issues may impact only a few products covered by this document. Consequently this document does not address such security issues. This standard is intende
30、d to specify uniform testing methods for performance evaluation of industrial-process instruments with analogue measured values and two- or multi-state outputs. Considerations other than the performances are listed in Clause 10. 2 Normative references The following referenced documents are indispens
31、able for the application of this document. For dated references, only the edition cited applies.

37、variable and y is the value of the output signal. The two-state instrument, having one pair of switching points x 1and x 2(x 2greater than x 1 ) has the relationships: y = y 1for x x 2For x 1 x x 2, y may be either y 1 or y 2 . It is y 1 if the last switching point crossed by x was x 1 . It is y 2 i
38、f the last switching point crossed by x was x 2 . 3.3 multi-state instrument a multi-state instrument (see Clause 7 and Figure 4) has n possible output values and n-1 pairs of switching points. Each pair of switching points may be investigated by the procedure given for the two-state instrument. 3.4

42、brations, external mechanical constraints, delivery of the instrument) specified in IEC 61298-1, Clause 6 apply, together with the additional information below. 4.1 Documentary information The manufacturer shall supply to the evaluating body information for installation, commissioning, operation, ro
43、utine maintenance and repair of the instrument. A spare parts list, together with a recommendation of the spare parts to be held in stock, shall be supplied. The language of written information for installation should be the language of the local user. All the relevant publications supplied by the m
44、anufacturer, automatically and on request, should be listed. If they do not contain a clear description, with adequate diagrams, of the operation of the instrument, or if they do not contain an adequate spare parts and specifications list, the nature of the inadequacy should be noted. Additionally,
45、any certificates indicating the degree of intrinsic safety and flameproofing, etc. of electrically powered instruments should be listed. This information should give details of the certificate numbers and the degree of protection provided. Procedures for installation, routine maintenance and adjustm
46、ent, repairs and overhaul should be examined by the actual performance of the required operation. This should be performed in accordance with the manufacturers instructions, so that an evaluation of the instructions can be carried out concurrently. 4.2 Safety Electrically powered instruments should
47、be examined to determine the degree to which their design protects them against accidental electric shock. 4.3 Installation The instrument should be installed and set to work according to the manufacturers instructions, taking account of the various applications which may be met in practice and whic
48、h require different procedures. The method of mounting specified by the manufacturer should be reported. Any restrictions on the use of the instrument caused by this method of mounting shall be noted with explanations. Any other aspects that may seem relevant to the ease or difficulty of installatio
49、n should be noted with explanations. Page7 EN610031:2004 4.4 Supply conditions Tolerances on supply conditions for mains supplied equipment are given in 6.2.2 of IEC 61298-1. For instruments with self-contained power supplies (e.g. battery-powered) the tolerances are different and shall be agreed. NOTE For pneumatic instrument care should be taken to ensure that pneumatic connections are leak tight. 5 General testing procedur
