This International Standard applies to pneumatic and electrical industrial-process controllers
using analogue signals which are in accordance with IEC 60381-1 and IEC 60381-2. The
provisions of this standard are applicable in principle to controllers having different, but
continuous signals.
This standard is intended to provide technical guidance for inspection and routine testing of
controllers, for instance, as acceptance tests or after repair. For a full evaluation,
IEC 60546-1 should be used. Quantitative criteria for acceptable performance are established
by agreement between manufacturer and user. The requirements of this standard are
effective when agreed upon by the manufacturer and the user.
