Industrial-process control systems. Instruments with analogue inputs and two- or multi-state outputs - Guidance for inspection and routine testing

BS EN 61003-2:2009 Industrial-process control systems. Instruments with analogue inputs and two- or multi-state outputs. Guidance for inspection and routine testing

BS EN 61003-2 gives guidelines for inspection and routine testing of electrical and pneumatic instruments with two- or multi-state output, for instance, for acceptance tests or after repair. For a full evaluation, IEC 61003-1 is used. Whenever possible any test carried out is to be in accordance with IEC 61298 series.

BS EN 61003-2 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.
