Overview

IEC 61010-2-202:2016 defines specific safety requirements for electric actuators and solenoids used with valves in industrial process and discrete control environments. As a part of the IEC 61010 series, this international standard supplements general safety rules laid out in IEC 61010-1:2010, providing additional detail relevant to electrically operated valve actuators. The purpose is to ensure safety in installation, operation, and maintenance, reducing risks such as electric shock, mechanical hazards, fire, and other operational dangers associated with these devices.

Key Topics

• Scope of Standard
  IEC 61010-2-202:2016 applies to electrically operated actuator and solenoid devices used for valve control, rated up to 600 V AC or 840 V DC, within industrial automation and process control systems.

  • Excludes actuators and solenoids for explosive atmospheres (covered by IEC 60079), safety-function devices (IEC 61508), valve positioners, and valve mechanical components.
  • Includes service personnel interfaces for installation and maintenance.

• Fundamental Safety Requirements

  • Electrical safety: protection against electric shock must be robust.
  • Mechanical safety: no accessible moving parts that cause hazard in normal or single-fault conditions.
  • Resistance to mechanical stress, fire propagation, heat, and fluids.
  • Safety measures for radiation, liberated gases, and explosion are expected.
  • Interlock protection and comprehensive risk assessment.

• Product Marking and Documentation

  • Detailed requirements for labels and supplied documentation.
  • Clear indication of power supply characteristics, operational limits, and maintenance instructions, including warnings if multiple disconnect switches are present.
  • Installation guides to ensure correct safety degree (e.g., according to IEC 60529 for protection levels).

• Testing and Verification

  • Specifies test scenarios including fault conditions, for instance, solenoids stopped under full energization.
  • Verification procedures for labeling, materials, and manufacturer instructions.

• Component Material Standards

  • Solenoid parts such as bobbins and insulation must meet flammability classification V-1 or better per IEC 60695-11-10.

Applications

IEC 61010-2-202:2016 is essential for manufacturers and users of electrical valve actuators and solenoids in:

• Chemical and petrochemical processing: Ensuring safe control of flow, pressure, or chemical dosing valves.
• Water treatment plants: Reliable and safe operation of electrically actuated valves in fluid handling systems.
• Pharmaceutical production: Guaranteeing compliance with high safety standards in process automation.
• Industrial automation: Supporting safe integration of actuator-based control systems on the factory floor.
• Control panel manufacturing: Assuring that component selection and system layout meet internationally recognized safety standards.

Adhering to this standard helps reduce workplace incidents, facilitates global trade by ensuring products meet international safety norms, and supports efficient maintenance and service practices.

SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT
FOR MEASUREMENT, CONTROL AND LABORATORY USE –

Part 2-202: Particular requirements
for electrically operated valve actuators

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61020-2-202 has been prepared by committee TC 65: Industrial-
process measurement, control and automation.

amendments to, IEC 61010-1.
This Part 2-202 supplements or modifies the corresponding clauses in IEC 61010-1 so as to
convert that publication into the IEC standard: Particular requirements for electrically operated
valve actuators.
Where a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies
as far as is reasonable. Where this part states “addition”, “modification”, “replacement”, or
“deletion”, the relevant requirement, test specification or note in Part 1 should be adapted
accordingly.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
It has the status of a group safety publication in accordance with IEC Guide 104.
A list of all parts in the IEC 61010 series, published under the general title Safety
requirements for electrical equipment for measurement, control and laboratory use, can be
found on the IEC website.
In this standard:
1) the following print types are used:
– requirements: in roman type;
– NOTES: in smaller roman type;
– conformity and test: in italic type;
– terms used throughout this standard which have been defined in clause 3: SMALL
ROMAN CAPITALS;
2) subclauses, figures, tables and notes which are additional to those in part 1 are numbered
starting from 101. Additional annexes are lettered starting from AA.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
