IEC 61010-2-202:2016

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.
