The purifier effectively improves our air quality, and at the same time brings us a pleasant mood, it can be said that in many conditional homes can be seen, the coverage rate in the EU developing countries is still higher, and domestic enterprises export to the EU CE certification is indispensable.
Introduction to EMC Testing:
The full name of EMC testing (electromagnetic compatibility testing) is Electro Magnetic Compatibility, which is defined as "the ability of equipment and systems to work normally in their electromagnetic environment and not to cause unbearable electromagnetic disturbance to anything in the environment" This definition contains two meanings, first, the equipment should be able to work normally in a certain electromagnetic environment, that is, the equipment should have a certain electromagnetic immunity (EMS); Secondly, the electromagnetic disturbance generated by the device itself must not have an excessive impact on other electronic products, i.e., electromagnetic disturbance (EMI).
The purifier needs to meet the standard requirements of EMC and safety LVD to apply for CE certification
1. EN335-1 Safety of Household Appliances and Similar Appliances Part 1.
2. EN335-2-5 Safety of Household Appliances and Similar Appliances Part 2.
3. Compatibility with EN1-3-2 current harmonic standard.
4. Compatibility with EN1-3-3 current harmonic standard.
5. EN5514-1 electromagnetic compatibility.
6. EN5514-2 electromagnetic compatibility.
EMC test items: EMC inspection items for EMC certification of household electrical appliances include electromagnetic emission (EMI) and electromagnetic immunity (EMS) two aspects: electromagnetic emission (EMI) test items are:
EMI's Inspection Items:
Conducted (CE) (15kHz 3MHz);
Intermittent interference voltage (click) (15kHz, 5kHz, 1.)4 MHz and 3MHz);
Interference power (3MHz 3MHz).
Harmonic current (2-4th harmonic).
EMS Inspection Items:
electrostatic discharge immunity;
Radiated electromagnetic field (8MHz 1 MHz) immunity;
Electrical fast transient burst immunity;
surge (lightning) immunity;
Injection current (15kHz 23MHz) immunity;
Voltage sag and short-term interruption immunity.
Information required for CE certification of air purifiers:
1. Company information: name, address, trademark, business license;
2. Product information: name, model, technical parameter table (if there are multiple models, the difference between the series of products is required);
3. Instruction manual;
Purifier CE certification process:
1. Fill in the certification application form and arrange for the test samples to be sent.
2. Sign back the contract and make the payment.
3. Start the test after receiving the sample and payment.
4. Confirm the draft information after passing the test.
5. Issue a certificate of conformity report.
The "CE" mark is a safety certification mark that is considered as a passport for manufacturers to open and enter the European market. CE stands for European Unity. In the EU market, the "CE" mark is a mandatory certification mark, whether it is a product produced by an enterprise within the European Union, or a product produced in other countries, if it wants to circulate freely in the EU market, it must be affixed with the "CE" mark to indicate that the product meets the basic requirements of the EU "New Approach to Technology Harmonization and Standardization" directive. This is a mandatory requirement for products under EU law.
