1. Scope of Application

Air conditioning products, comprising a motor-driven fan and elements for changing the temperature and humidity, including those machines in which the humidity cannot be separately regulated, used for household and similar purposes (With a rated current not exceeding 25 A; excluding 3-phase power products):

Window or wall types, self-contained (monoblock) or “split-system” (separate indoor and outdoor units), with a cooling capacity not exceeding 26.38 kW – HS Code: 8415.10.10;
Air conditioners incorporating a refrigerating unit and a valve for reversal of the cooling/heat cycle (reversible heat pumps), with a cooling capacity not exceeding 21.10 kW – HS Code: 8415.81.93;
Air conditioners incorporating a refrigerating unit, with a cooling capacity not exceeding 26.38 kW – HS Code: 8415.82.91;
Air conditioners not incorporating a refrigerating unit, with a cooling capacity not exceeding 26.38 kW – HS Code: 8415.83.91.

Pursuant to QCVN 9:2012/BKHCN and Amendment 1:2018 QCVN 9:2012/BKHCN, air conditioners must undergo testing and conformity certification, bear the conformity mark (CR Mark), and be subject to market inspection by quality control authorities. Accordingly, air conditioners must meet the technical requirements of TCVN 7492-1:2018 (replacing TCVN 7492-1:2010) regarding Electromagnetic Compatibility.

2. Technical Requirements

TCVN 7492-1:2018 (CISPR 14-1:2016)specifies the technical testing requirements for each type of air conditioner as follows:

2.1. Single-Way (Cooling Only) Air Conditioners

Limits for disturbance voltage at load terminals and additional terminals;
Limits for disturbance voltage at the mains terminals;
Limits for disturbance power (30 MHz – 300 MHz);
Limits for discontinuous interference (clicks).

2.2. Two-Way (Heat Pump) Air Conditioners

Limits for disturbance voltage at load terminals and additional terminals;
Limits for disturbance voltage at the mains terminals;
Limits for disturbance power (30 MHz – 300 MHz);
Limits for discontinuous interference (clicks).

After obtaining the Electromagnetic Compatibility (EMC) Test Report for Air Conditioners in Vietnam according to QCVN 9:2012/BKHCN, enterprises shall perform conformity certification under Method 1 (typical sample testing) and carry out the declaration of conformity in accordance with current regulations. Upon completion of the declaration procedures, the enterprise is permitted to self-affix the conformity mark (CR mark) onto products that match the information in the Declaration of Conformity and the Certificate of Conformity.

Phuc Gia® is one of the organizations designated by the Ministry of Science and Technology to conduct electromagnetic compatibility testing for air conditioners according to Decision No. 2899/QD-BKHCN on the designation of conformity assessment organizations.

With a system of modern equipment and rigorous testing procedures, Phuc Gia® is committed to providing an Electromagnetic Compatibility (EMC) Test Report for Air Conditioners in Vietnam per QCVN 9:2012/BKHCN and Amendment 1:2018 QCVN 9:2012/BKHCN that is accuracy, objectivity, timeliness, and reliability, meeting current EMC regulations for household and office electrical and electronic products.

In addition to electromagnetic compatibility (EMC) testing, enterprises manufacturing or importing air conditioners must also comply with requirements for energy efficiency testing and energy labeling as regulated by the Ministry of Industry and Trade.
