This clause of Part 1 is applicable, except as follows: 1.1 Scope 1.1.1 Equipment included in scope Replacement of 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. 1.1.2 Equipment excluded from scope Addition at the end of the list: This standard excludes: aa) electric ACTUATORS and SOLENOIDs for use in domestic or commercial applications; NOTE – 1 – These are covered by other IEC or ISO standards, such as IEC 60730, etc. bb) electric ACTUATORs and SOLENOIDs performing a safety function; NOTE – 2 – These are covered by other IEC or ISO standards, such as IEC 61508, etc. cc) positioners. NOTE – 3 – A 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. 1.2 Object 1.2.2 Aspects excluded from scope Addition at the end of the list: aa) mechanical parts/aspects of valves. 1.2.101 Aspects included in other applicable standards Where electric ACTUATORs and SOLENOIDs are required to comply with requirements of other IEC or ISO standards, aspects fully covered in these standards can replace requirements as given in IEC 61010-1. Where aspects covered in IEC 61010-1 are not fully covered in these IEC or ISO standards, tests of IEC 61010-1 shall be conducted as far to ensure that no HAZARD can occur in NORMAL or in SINGLE FAULT CONDITION. NOTE – IEC 61010-1:2010, Figure 15 of 14.1 gives a general overview of dealing with components within the scope of other IEC or ISO standards. A similar approach can be used for equipment and sub-assemblies. Example – Clauses 8 and 9.1 to 9.5 can generally be considered sufficiently covered where IEC 60079 has been applied.
