What Is Electric Iron Testing?

Electric iron testing is the process of evaluating an electric iron against applicable safety and performance requirements. It checks whether the appliance can operate under its intended conditions without creating unacceptable risks for the user.

The testing process examines the complete appliance, including its electrical connections, heating system, temperature-control mechanism, insulation, enclosure, handle, soleplate, power cord and other relevant components.

The main purpose is to confirm that:

• The appliance provides adequate protection against electric shock.
• Electrical insulation remains effective during operation.
• The heating system operates within the applicable safety limits.
• The appliance does not create dangerous temperatures.
• The power cord and internal wiring are properly designed.
• The construction can withstand relevant mechanical stresses.
• Steam and water-related functions operate safely where applicable.
• Product markings and instructions provide the required information.

Electric iron testing is not limited to checking whether the iron heats up. A product may heat correctly and still fail important electrical safety tests.

For this reason, manufacturers should evaluate the complete appliance according to the relevant clauses of the applicable Indian Standard.

---

Which Indian Standard Applies to Electric Iron Testing?

The main product-specific safety standard for electric irons in India is:

IS 302 (Part 2/Sec 3):2024 / IEC 60335-2-3:2022 - Household and Similar Electrical Appliances - Safety, Part 2: Particular Requirements, Section 3: Electric Irons.

This is the second revision of the electric iron safety standard.

Electric irons must also meet the applicable general safety requirements under IS 302 (Part 1). The particular standard and general standard should be read together, including their applicable national requirements.

Important Update: IS 302 (Part 2/Sec 3):2024

The earlier standard was IS 302 (Part 2/Sec 3):2007. BIS published the revised 2024 version, and the concurrent-running period ended on 23 February 2025.

After this date, the old 2007 standard was withdrawn for the relevant certification requirements. Manufacturers should therefore use the revised 2024 standard for current electric iron certification.

The revised standard introduced or clarified several important requirements, including:

• Additional provisions for DC-supplied and battery-operated appliances.
• External accessible surface temperature requirements.
• Changes to product marking and user instructions.
• Requirements relating to charging metal-ion batteries.
• Additional mechanical strength requirements for irons.
• Changes to safeguards against excessive pressure.
• Updated requirements for protective devices.

These changes make it important for manufacturers to review their product designs and testing arrangements before applying for certification.
