DIN EN 61003-1:2017-06

The assessment methods specified in this part of IEC 61003 are intended to be used by manufacturers to determine the performance of their products and by users or independent test bodies to verify the performance claimed by manufacturers. The test conditions in this standard, for example the range of ambient temperatures and power supply, correspond to those encountered in normal use. Consequently, the values specified here shall be used if no other values are specified by the manufacturer. The tests specified in this standard are not necessarily sufficient for devices specifically designed for exceptionally severe conditions. Conversely, a limited set of tests may be appropriate for equipment designed for a limited range of conditions. It is desirable that there should be the closest possible cooperation between the assessing body and the manufacturer. The manufacturer's specifications for the device shall be taken into account when the test program is decided and the manufacturer should be invited to comment on both the test program and the results. The manufacturer's comments on the results should be included in any report prepared by the investigating organization. This part of IEC 61003 is applicable to pneumatic and electric industrial-process instruments or control device using measured values that are continuous signals - either a mechanical (position, force etcetera) or a standard electric signal. These instruments or process control systems modules may be used as controllers or as switches for alarm and other similar purposes. Devices or modules for process control technology with feedback are not covered by this standard. Electronic product safety issues may impact only a few products covered by this document. Consequently this document does not address such safety issues. This standard is intended to specify uniform terminologies and testing methods for performance evaluation of industrial-process instruments or process control systems modules with analogue measured values and two- or multi-position outputs. Considerations other than the performances are listed in Clause 10. The responsible committee is DKE/K 961 "Elektrische Messwertaufnehmer und Messgrößenumformer" ("Electrical measurement sensors and transducers") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
