I. OVERVIEW OF ELECTROMAGNETIC COMPATIBILITY

1. What is Electromagnetic Compatibility (EMC)?

According to QCVN 9:2012/BKHCN, “Electromagnetic Compatibility (EMC) is the ability of equipment or a system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic interference to anything in that environment.” Quality control for electrical and electronic products aims to limit electromagnetic interference/electromagnetic compatibility issues that significantly affect the proper operation of other electrical and electronic devices.

2. Why is Electromagnetic Compatibility testing necessary?

Household electrical and electronic equipment in the mandatory testing list under QCVN 9:2012/BKHCN includes: vacuum cleaners; household washing machines; refrigerators, freezers, commercial refrigerators; air conditioners; self-ballasted lamps; hair dryers; blenders; meat grinders; fruit juicers; egg beaters; electric stoves (including induction hobs); and microwave ovens (including combination types). These are devices used daily for cooling, refrigeration, cooking, laundry, cleaning, drying, and lighting.

Furthermore, these products are commonly used in various environments, from homes and offices to public spaces like supermarkets, restaurants, and entertainment areas. They are often placed near other electronic devices and operate in environments with significant electromagnetic influence, which can easily cause electromagnetic interference, reducing performance or even creating hazards for users. Therefore, Electromagnetic Compatibility (EMC) testing not only ensures safety but also guarantees that these products can operate stably and efficiently in any environment.

3. Current Legal Regulations on Electromagnetic Compatibility

Due to the concerning effects of electromagnetic interference, electromagnetic radiation, and electromagnetic compatibility issues, the Ministry of Science and Technology issued Circular No. 11/2012/TT-BKHCN accompanied by QCVN 9:2012/BKHCN – “National Technical Regulation on Electromagnetic Compatibility for Household Electrical and Electronic Equipment and Similar Purposes.” Accordingly, from April 12, 2012, the products specified in the table below must have goods labels in accordance with labeling laws; must undergo testing and conformity certification according to QCVN 9:2012/BKHCN, bear the conformity mark (CR mark), and be subject to market inspection by product quality control authorities as required by QCVN 9:2012/BKHCN.

II. EMC TESTING FOR SELF-BALLASTED LAMPS IN VIETNAM (COMPACT FLUORESCENT LAMPS) ACCORDING TO QCVN 9:2012/BKHCN

1. What are Self-ballasted Lamps – Compact Fluorescent Lamps?

A ballast (also known as a choke or stabilizer) is utilized in lighting systems, primarily for lamps such as compact and LED varieties. Simply put, this device ensures the lighting equipment operates more stably and achieves significantly higher durability. Electronic ballasts operate at high frequencies, providing a precise amount of electricity to the luminaire and minimizing flickering. They also feature an automatic power-off capability during installation or removal. An electronic ballast is a circuit board combining rectification and inversion to generate alternating current through the resonance of the lamp ends. This internal component is a primary focus during EMC Testing for Self-Ballasted Lamps in Vietnam.

According to National Standard TCVN 7186:2018 (CISPR 15:2018), a self-ballasted lamp is defined as a “unit which cannot be dismantled without being permanently damaged, provided with a light source and any additional elements necessary for starting and stable operation of the light source, and provided with one or two standard lamp caps according to IEC 60061-1 for connection to a lamp holder or a luminaire.” The light source component is non-replaceable. The term “self-ballasted lamp” is a general term for all designs capable of independent operation without external auxiliary gear, except for the lamp holder.

Compact Fluorescent Lamps (CFLs) are low-power fluorescent lamps, often shaped in U-bends (1U to 3U) or compact spirals to match incandescent bulb sizes. CFLs emit light when a mixture of three phosphors is exposed to ultraviolet light from mercury atoms. The structure consists of the glass tube, the ballast, and the lamp cap, providing a brightness 4-5 times higher than incandescent bulbs of the same wattage.

2. Why must EMC Testing for Self-Ballasted Lamps in Vietnam (CFLs) be conducted according to QCVN 9:2012/BKHCN?

Compact fluorescent lamps (self-ballasted lamps) fall under the category of products that must comply with legal requirements for electromagnetic compatibility before being placed on the market in many countries worldwide, including Vietnam (QCVN 9:2012/BKHCN). This ensures the products meet established safety and quality standards.

Self-ballasted lamp samples (CFLs) are devices used everywhere and are often operated alongside various other electrical and electronic equipment. Given their high frequency of use, it is critical and necessary for these products to undergo EMC Testing for Self-Ballasted Lamps in Vietnam as required by QCVN 9:2012/BKHCN. This ensures stable operation for the device itself and limits electromagnetic interference that could disrupt usage, reduce performance, or cause unintended malfunctions in surrounding electronics.

3. Specified Disturbance Limits / Testing Parameters for Self-Ballasted Lamps

Limits for disturbance voltage at the mains terminals;
Limits for disturbance power (30 MHz to 300 MHz).
