I. OVERVIEW OF ELECTROMAGNETIC COMPATIBILITY

1. What is Electromagnetic Compatibility?

Electromagnetic Compatibility (EMC – Electro Magnetic Compatibility) is the ability of electrical and electronic equipment to operate normally in an electromagnetic environment without affecting the operation of other equipment.

If quality is not controlled, electrical and electronic products can cause electromagnetic interference/compatibility issues, which can lead to significant impacts on the normal operation of other electrical and electronic devices.

2. Why must Electromagnetic Compatibility (EMC) be managed according to QCVN 9:2012/BKHCN for Vacuum Cleaners / Handheld Vacuum Cleaners?

Any electrical and electronic product generates electromagnetic interference and compatibility issues, whether large or small. Vacuum Cleaners / Handheld Vacuum Cleaners are no exception.

When electrical and electronic equipment in general, as well as Vacuum Cleaners / Handheld Vacuum Cleaners in particular, are operating—even under normal conditions—they emit electromagnetic radiation (emissions), also known as electromagnetic interference waves, with varying wavelengths and intensities. The higher the radiation intensity, the greater the impact on the normal operation of other equipment and the surrounding environment.

Harmful effects of electromagnetic interference and compatibility issues from electrical and electronic equipment

Practical examples of the harmful effects of electromagnetic interference and compatibility issues in our lives include: distorting the results of blood pressure monitors; causing malfunctions in the operation of escalators, automatic doors, elevators, and cameras; or even significantly affecting human health, such as nervous system dysfunction, immune system dysfunction, reproductive health impacts, or even cancer and many other diseases.

Due to the significant and concerning impacts of electromagnetic radiation and compatibility issues, on April 12, 2012, the Ministry of Science and Technology issued the National Technical Regulation QCVN 9:2012/BKHCN on electromagnetic compatibility for household electrical and electronic equipment and similar purposes. This regulation stipulates the technical and management requirements for electromagnetic interference emission limits for household electrical and electronic equipment and similar purposes, including Vacuum Cleaners / Handheld Vacuum Cleaners.

3. Currently Effective Regulations

II. TESTING VACUUM CLEANERS ACCORDING TO QCVN 9:2012/BKHCN ON ELECTROMAGNETIC COMPATIBILITY

1. What is a Vacuum Cleaner?

A vacuum cleaner is an electronic device designed to help remove dust, debris, and other small particles from surfaces. The operating principle of the machine is to use suction technology to create a strong airflow, thereby sucking dust particles and waste into an internal compartment or dust bag.

The machine is widely applied in households and industry to clean living and working spaces, helping to maintain a clean and healthy environment. There are many different types of vacuum cleaners on the market, including both corded (electric) and battery-powered product lines, with diverse features and suction power to suit user needs.
