1. What is Electromagnetic Compatibility?

Electromagnetic Compatibility (EMC) refers to the capacity of electrical and electronic devices to function correctly within their electromagnetic environment without interfering with the performance of surrounding equipment. This concept is fundamental to ensuring the safety and reliability of modern household appliances.

Without rigorous quality control—such as EMC Testing for Juicers in Vietnam, EMC Testing for Air Conditioners, EMC Testing for Microwaves in Vietnam, or EMC Testing for Hand Mixers in Vietnam—electrical and electronic products may generate harmful electromagnetic interference (EMI).

This lack of compatibility can cause major disruptions, leading to malfunctions or total failure in other nearby electrical and electronic systems, highlighting the necessity of achieving full Technical regulation Compliance.

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

Any electrical or electronic product generates electromagnetic interference and compatibility issues, whether large or small. Juicers are no exception.

When electrical and electronic equipment in general, and Juicers 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.

What are the harmful effects of electromagnetic interference and compatibility issues from electrical and electronic equipment?

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

Due to these concerning impacts, on April 12, 2012, the Ministry of Science and Technology issued the National Technical Regulation QCVN 9:2012/BKHCN. This regulation stipulates the technical and management requirements for electromagnetic interference emission limits for household electrical and electronic equipment, including Juicers (stipulated in Amendment 1:2018 QCVN 9:2012/BKHCN dated June 6, 2018).

3. Currently Effective Regulations
