61 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

62 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

63 international co-operation on all questions concerning standardization in the electrical and electronic fields. To

64 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

65 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

66 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

67 in the subject dealt with may participate in this preparatory work. International, governmental and non-

68 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

69 with the International Organization for Standardization (ISO) in accordance with conditions determined by

71 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

72 consensus of opinion on the relevant subjects since each technical committee has representation from all

74 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

75 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

76 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

78 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

79 transparently to the maximum extent possible in their national and regional publications. Any divergence

80 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

82 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

83 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

86 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

87 members of its technical committees and IEC National Committees for any personal injury, property damage or

88 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

89 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

111 When a particular subclause of IEC 61326-1 is not mentioned in this part, that subclause

112 applies as far as is reasonable. When this standard states “addition”, “modification” or

113 “replacement”, the relevant text in IEC 61326-1 is to be adapted accordingly.

144 configurations, operational conditions and performance criteria for transducers with integrated

146 This standard applies only to transducers characterized by their ability to transform, with the

147 aid of an auxiliary energy source, a non-electric quantity to a process-relevant electrical

148 signal, and to output the signal at one or more ports. This standard includes transducers for

238 algebraic difference between the values of the upper and lower limits of the measuring range

255 A system for monitoring the behaviour of the EUT and for registering the output values shall

256 be designed in such a way that the electromagnetic compatibility characteristics of the EUT

257 are not impaired. The monitoring system shall also be designed such that its response is not

258 affected by the immunity tests. The input impedance of the monitoring system shall

259 correspond to the terminating impedance of the transducer, specified by the manufacturer.

260 The distance between the monitoring system and the EUT should be at least 1,5 m.

261 The measurement uncertainty and the bandwidth of the monitoring system shall be adapted to

264 The tests shall be conducted in compliance with the environmental conditions for the

265 transducer specified by the manufacturer and using the specified supply voltage.

266 In the case of battery-operated transducers that can also be used when connected with a

267 power supply, both operating modes (stand-alone and externally supplied) shall be tested.

268 In cases in which the manufacturer's installation instructions stipulate the use of external

269 protective equipment or particular protective measures that are explicitly stated in the

270 operating manual, the test requirements given in this part of the standard shall be applied for

282 Transducers shall be operated during the test with all lines connected, provided the ports do

283 not have functions that contravene the definition of a transducer's function.

285 Transducers shall be set to the most sensitive ranges or combination of ranges unless other

286 ranges are known to provide worst-case immunity results within normal application.

287 Only operational functions compliant with the specified use under the nominal conditions are

288 permitted. Defined functions that cannot be set under electromagnetic compatibility test

289 conditions shall be simulated by appropriate measures. This shall be done in such a way that

290 the electromagnetic compatibility behaviour of the transducer is not affected.

292 specifications. If no such specifications are given, the tests shall be carried out with the

306 shall be checked once again after ESD, fast transient (burst) and surge tests. If the

307 manufacturer's specifications are not satisfied, the transducer is deemed to have failed the

314 The performance criteria are used to assess the defined functions of a transducer under the

315 effects of external electromagnetic disturbances. Since a transducer is often part of a chain of

316 functions in a large process, effects on the overall process due to malfunctions of a

317 transducer caused by external interference factors cannot be predicted without great difficulty.

318 For this reason, it is particularly important that the behaviour of transducers under the

319 influence of electromagnetic disturbances is described with performance criteria.
