Defines the safety requirements for electric ACTUATORs and SOLENOIDs, as applied to valves, intended to be installed in an industrial process or discrete control environment.

This clause of Part1 is applicable, except as follows. 1.1 Scope 1.1.1 Equipment included in scope Replacement: Replace the text by the following paragraphs: This part of IEC61010 specifies the safety requirements for electric ACTUATORs and SOLENOID s, as applied to valves, intended to be installed in an industrial process or discrete control environment. This part of IEC61010 specifies: particular safety requirements for general purpose electrically operated valve ACTUATOR s and SOLENOID s, related verification tests. The general purpose electrically operated valve ACTUATOR s and SOLENOID s, covered by this part of IEC61010 are limited to: those rated 600V alternative current/840V direct current or less, Service personnel interface to equipment included in the scope of this document. 1.1.2 Equipment excluded from scope Addition at the end of the list: This standard excludes electric ACTUATOR s and SOLENOID s for use in explosive atmospheres, as covered by the IEC60079 series of standards; mechanical parts/aspects of valves; ACTUATOR s and SOLENOID s performing a safety function as covered by the IEC61508 series of standards; POSITIONERs. NOTEA positioner is defined as a \'physical unit delivering an additional, often mechanical, feedback to a mechanical final controlling element that improves its velocity and precision\' in IEC60050‑351:2013, 351-56-17.
