IEC 60730-2-15:2026

Overview

IEC 60730-2-15:2026 is an international standard developed by the International Electrotechnical Commission (IEC) for automatic electrical air flow, water flow, and water level sensing controls. This standard provides essential requirements for the design, construction, and testing of such controls used in various applications, including household appliances, boilers, building automation, and commercial equipment. The goal is to ensure both the inherent safety and functional safety of automatic electrical controls that sense or regulate air and water flows or water levels.

Key Topics

• Scope and Application
  IEC 60730-2-15:2026 applies to automatic controls for:

  • Boilers with a maximum pressure of 2,000 kPa (20 bar)
  • Household appliances such as dishwashers, washing machines, and air conditioning equipment
  • Building automation and smart-enabled systems within ISO 16484 and IEC 63044 series
  • Equipment used in public buildings, offices, hospitals, farms, and commercial facilities

• Types of Controls Covered

  • Air flow sensors
  • Water flow sensors
  • Water level sensors, including float and electrode-based designs
  • Mechanically or electrically operated controls
  • Controls integrated with manual elements if electrically/mechanically combined
  • Controls using NTC or PTC thermistors (requirements in Annex J)

• Safety and Performance Requirements

  • Protection against electric shock
  • Mechanical and electrical endurance
  • Resistance to environmental factors (humidity, dust)
  • Functional safety, including response times and action sequences related to equipment safety
  • Constructional robustness, including secure cable attachment and the reliability of components

• Exclusions

  • Not intended for controls used exclusively in industrial process applications (unless no relevant standard exists)
  • Not applicable to pressure-sensitive controls (addressed by IEC 60730-2-6)
  • Not addressing output signal integrity to networked devices unless specifically evaluated

Applications

Implementing IEC 60730-2-15:2026 ensures consistent performance and safety for automatic electrical sensing controls across various sectors:

• Residential and Commercial Appliances

  • Ensures reliable and safe operation of washing machines, dishwashers, and air-conditioning chillers
  • Protects users and property by ensuring accurate water level detection in boilers and tanks

• Building Automation

  • Supports integration within Building Automation and Control Systems (BACS) and Home and Building Electronic Systems (HBES)
  • Facilitates smart grid integration and remote operation, including smartphone and computer interfaces

• Public and Institutional Facilities

  • Provides safety and functionality for controls in offices, hospitals, retail stores, and commercial kitchens
  • Addresses the unique needs of applications such as farm irrigation systems, cooling towers, and water pumps

• Smart and Connected Systems

  • Enables remote management and monitoring of HVAC and water systems
  • Enhances the reliability of controls in energy management and networked building systems
