scope:

NEN-EN-IEC 61003-2 gives guidelines for inspection and routine testing of electrical and pneumatic instruments with two- or multi-position output, for instance, for acceptance tests or after repair, and it is to be used in conjunction with IEC 61003-1:2016 IEC 61298-2:2008 and IEC 61298-3:2008. This part of IEC 61003 is applicable to electrical and pneumatic industrial-process instruments, using measured values that are continuous signals. The set point value may be either a mechanical (position, force, etc.) or a standard signal. These instruments may be used as controllers or as switches for alarms and other similar purposes. Quantitative criteria for acceptable performance should be established by agreement between manufacturer and user, and the report on the tests clarifies which tests were carried out. The requirements of this standard are effective when agreed by the manufacturer and the user.
