EMC and CCC certification need to be certified or something

EMC certification is electromagnetic compatibility certification, which refers to the ability of equipment and systems to function properly in their electromagnetic environment without causing unenvious electromagnetic disturbance to anything in the environment. According to the regulations, all electrical and electronic products must be EMC certified and affixed with the CE mark before they can be sold on the European Community market.

In order for a product to comply with EMC requirements, EMC testing should be performed at all stages of the product lifecycle. The exact nature of the test and whether the Zen school is much needed will depend on the specific situation, the product needs, and the nature of the product introduction. EMC testing may involve a development test phase, a pre-compliance test phase, an EMC conformance test phase, and a production test phase.

It is useful to be able to classify the different phases of EMC testing, as each stage has slightly different requirements, including conducted emissions, radiated emissions, conducted immunity, radiation immunity, etc.

CE certification is limited to the basic safety requirements in terms of the safety of the product not to endanger humans, animals and goods, and not to the general quality requirements. Therefore, the precise meaning is: the CE mark is a safety mark and not a quality mark.

It forms the core of the European directive"Main requirements:"。

All products with the "CE" mark can be sold in EU member states without meeting the requirements of each member state, thus realizing the free circulation of goods within the EU member states. In the European Economic Area (European Union, member states of the European Free Association**), the use of the CE mark is increasing, and the use of the CE mark indicates that it meets the requirements of a series of European directives such as safety, health, environmental protection and consumer protection.

EMC is an American information storage information technology company, mainly engaged in information storage and management products, services and solutions. EMC Corporation was founded in 1979 and is headquartered in Hopkinton, Massachusetts. In October 2003, EMC was acquired by Dell.

What is the relationship between EMC and CE marking?

EMC refers to the electromagnetic compatibility return to dry directive, generally live products exported to the European Union need to do EMC electromagnetic compatibility directive, such as home appliances CE certification needs to meet: EMC directive + LVD directive + RoHS directive, etc., according to the functional assessment, EMC directive orange Shihong is divided into many specific test standards, such as EN 55014.

1.What is EMC Certification?

EMC certification is actually EMC testing, EMC stands for electromagnetic compatibility, which measures whether electrical or electronic products can withstand electromagnetic interference that may exist in the atmosphere, and also will not cause electromagnetic interference to the atmosphere, which may affect the correct operation of other electrical products.

Different product groups (automotive, medical, IT, etc.) are subject to different directives and therefore have different EMC acceptance criteria, which are specified in internationally recognized standards. A product is considered to meet EMC requirements if it meets the specific criteria or details of the criteria applicable to its intended end use.

Directives to be followed when applying for CE certification for household appliances. On March 29, 2014, the official journal of the European Union announced the new version of the CE certification Low Voltage Directive 2014 35 EU, which will replace the original CE certification Low Voltage Directive 2006 95 EC will be implemented on April 20, 2016.

The new EMC Directive for Electromagnetic Compatibility in CE, the updated EMC Directive number 2014 30 EU, will enter into force on April 18, 2014. The old EMC Directive 2004 108 EC will be repealed on April 20, 2016.

General electrical and electronic products are mainly subject to the following two directives:

LVD Directive: The abbreviation of the Low Voltage Electrical Appliances Directive, all electrical products sold in the European Community must comply with the Directive.

EMC Directive: The abbreviation of electromagnetic compatibility, EMC includes two categories: EMI (interference) and EMS (anti-interference).

Wireless products need to additionally comply with the requirements of the R&tte Directive. Mechanical products need to meet the requirements of MD, medical products need to be certified by the MDD Directive, pressure equipment needs to meet the requirements of the PED Directive, and personal protective equipment needs to meet the requirements of the PPE Directive,......

The latest RoHS directive is 2011 65 EU, and the items required to be tested are 6 imitation Huai Zheng items, and the directive comes into effect as the RoHS directive.

What does EMS test mainly consist of?

ESD Immunity Test.

RS RF electromagnetic field radiated immunity test.

CS RF field-sensing conducted nuisance immunity test.

DIP voltage sag, short interruption and voltage change immunity testing.

As early as July 21, 2017, the European Commission officially issued Decision (EU) 2017 1357, which sets out the restrictions on the harmonization of the implementation of the standard EN60335-2-9 (safety standard for household and similar electrical appliances), which is in force immediately from the date of its promulgation.

CE certification is divided into electromagnetic compatibility (EMC) and low voltage directive (LVD).

Overview of the EMC Electromagnetic Compatibility Directive:

EMC electromagnetic compatibility is the abbreviation of electromagnetic compatibility, the World Electrotechnical Commission (IEC) standard for EMC electromagnetic compatibility refers to: the equipment or system in the electromagnetic environment of the site can operate in accordance with the requirements without intolerable electromagnetic disturbance of any equipment in the environment. In the meantime, EMC includes two parts: EMI (electromagnetic disturbance) and EMS (electromagnetic anti-interference), EMI means that the electromagnetic disturbance to the local environment during the normal operation of the equipment cannot exceed the certain limit; EMS refers to the fact that the appliance has a certain degree of immunity to electromagnetic disturbances existing in the environment of the site, that is, electromagnetic sensitivity.

In order to standardize the handling of electromagnetic compatibility of electrical equipment in EU member states, it is the harmonization of the regulations on electromagnetic compatibility of EU member states, and the 89 336 EEC electromagnetic compatibility directive was promulgated on May 1, 1989, and began to be mandatory on January 1, 1996, and the current directive is 2004 108 EC.

EMC is not a certification, it is a directive, it is a directive of CE certification, do you need to apply for CE?
