Safety requirements for electrical equipment for measurement, control and laboratory use -- Particular requirements for electrically operated valve actuators
This clause of Part 1 is applicable, except as follows.
Replacement:
Replace the text by the following paragraphs:
This part of IEC 61010 specifies 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 part of IEC 61010 specifies:
particular safety requirements for general purpose electrically operated valve ACTUATORs and SOLENOIDs,
related verification tests.
The general purpose electrically operated valve ACTUATORs and SOLENOIDs, covered by this part of IEC 61010 are limited to:
those rated 600 V alternative current/ 840 V direct current or less,
Service personnel interface to equipment included in the scope of this document.
Addition at the end of the list:
This standard excludes
electric ACTUATORs and SOLENOIDs for use in explosive atmospheres, as covered by the IEC 60079 series of standards;
mechanical parts/aspects of valves;
ACTUATORs and SOLENOIDs performing a safety function as covered by the IEC 61508 series of standards;
POSITIONERs.
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 IEC 60050‑351:2013, 351-56-17.
