Overview

IEC 60730-2-8:2000/AMD1:2002 is an important amendment to the international standard governing automatic electrical controls for household and similar use, specifically addressing electrically operated water valves. Published by the International Electrotechnical Commission (IEC), this amendment focuses on particular mechanical and electrical requirements for these water valves, ensuring safety, reliability, and performance in domestic applications.

This amendment supplements the base standard IEC 60730-2-8 and is designed to be used in conjunction with IEC 60730-1, the general requirements for automatic electrical controls. It integrates updates primarily related to testing procedures, mechanical integrity, thermal performance, electrical endurance, and electromagnetic compatibility (EMC) of electrically operated water valves.

Key Topics

  • Mechanical and Electrical Testing Requirements
    The amendment elaborates on testing requirements for the actuators and components of water valves under various conditions:

    • Heating and cooling tests to simulate operating temperatures.
    • Dry condition tests to verify valve endurance in loss of water supply scenarios.
    • Temperature limits during blocked output state to prevent overheating.
    • Overvoltage and undervoltage tests ensuring electrical resilience.
  • Creepage and Clearance Distances
    Updated titles and sections address requirements for electrical insulation including:

    • Creepage distances.
    • Clearances through solid insulation. These ensure safe electrical operation and prevent short circuits or electrical breakdown.
  • Guidance on Electronic Disconnection
    An important addition is guidance related to the use of electronic disconnection methods within controls for these valves, clarifying applicability and ensuring safety compliance.

  • Electromagnetic Compatibility (EMC) Criteria
    Detailed EMC immunity requirements address electrical fast transients and burst tests with valves energized:

    • Emphasizing immunity to rapid transient bursts.
    • Specific compliance criteria post testing to maintain insulation and safety integrity.
    • Particular notes on exemptions and alternate requirements for regions such as Canada and the USA.
  • Specific Requirements for Household Appliances
    Additional conditions are set for valves incorporated in domestic appliances covered under IEC 60335, particularly concerning:

    • Operation under abnormal conditions such as water supply loss.
    • Limitations on operating time or duty cycles.
  • National Exceptions and Notes
    The amendment clarifies national practice deviations, noting exclusions or differentiations in countries like Canada, Japan, and the USA on certain tests and requirements.

Applications

IEC 60730-2-8 Amendment 1 is critically applied in:

  • Automatic water control valves in household appliances
    Such as dishwashers, washing machines, and water heaters, where electrical control of water flow is essential for safety and function.

  • Plumbing and water supply automation
    Electrically operated valves used in smart home water management systems, enabling automated control and safeguarding against leaks or dry-running conditions.

  • Heating, Ventilation, and Air Conditioning (HVAC) systems
    Electrically actuated water valves regulating heating and cooling fluids as part of energy-efficient climate control solutions.

  • Appliance manufacturing and compliance testing
    Manufacturers rely on this standard amendment to guide product design, safety testing, and certification aligned with international norms.

Related Standards

  • IEC 60730-1 (Automatic electrical controls - Part 1: General requirements)
    Serves as the foundational document for automatic electrical controls, providing general testing, design, and safety principles referenced by this amendment.

  • IEC 60335 series (Household and similar electrical appliances - Safety)
    Covers broader safety requirements for household appliances that use water valves, specifying conditions under which these valves are considered abnormal operating conditions.

  • IEC 60085 (Electrical insulation - Thermal evaluation and classification)
    Defines thermal classes used for insulation temperature limits referenced in valve actuator temperature tests.

  • National and regional EMC standards
    Including supplementary requirements especially for North American markets reflecting different EMC compliance approaches.


By adhering to IEC 60730-2-8 Amendment 1, manufacturers and stakeholders ensure that electrically operated water valves meet critical electrical, mechanical, and environmental safety standards for household and similar applications. This promotes consumer safety, reliability, and functional excellence in automated water control systems worldwide.
