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 set 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 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 intended 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.
