In the past, European Union countries on imports and sales of the product requirements vary, according to the standards of a country-made goods to other countries may not be CE-certified logo on city, as part of efforts to eliminate trade barriers, and CE certification came into being. Therefore, the CE certification on behalf of the European Unity (CONFORMITE EUROPEENNE).
Meaning of the CE certification mark: CE certification acronyms for notation and stick the marking of CE certified products comply with the main requirements of the European directive (Essential Requirements), and to confirm that the product has passed the corresponding conformity assessment procedures and/or manufacturer's Declaration of conformity and truly become products are allowed to enter the market of the European Union pass. Order for request of stick the marking of CE certification of industrial products without CE mark, shall not be marketed, and stick the marking of CE certification to market products, found not to meet the safety requirements, be ordered to be withdrawn from the market, continuous violation of the directives provisions of the CE certification mark will be restricted or prohibited from entering the EU market or forced to withdraw from the market.
At present, involving electromagnetic radiation of all trades has become atmospheric pollution, water pollution, noise pollution and pollution, different band along with the update of the technological revolution and new applications, many of the significant increase in the frequency of electromagnetic radiation exposure levels in. Although the health hazards caused by electromagnetic radiation in different countries have different views, but its hazards to the public is recognized. Who WHO Yu 1996 established has international electromagnetic radiation (EMF) plans, proposed super low frequency (ELF), if (IF) and the RF (RF) electric magnetic field (0Hz-300GHz) of static electric magnetic field on human health of effect. in on July 12, 1999 of EU Council recommends (1999/519/EC) in the recommends has mass on electric magnetic field of exposed limit. and May 2003 EU electrical standard Committee (CENELEC) announced has new The technical standard EN50366. The standard specification for the household electrical appliances of electromagnetic fields generated by measurement and assessment methods. On April 29, 2004, OJEU EN50366 officially listed in the requirements, so the standards have become household appliances products LVD (Low Voltage Directive) one of the certification programs. EMF is different from EMC, EMF is to ensure personal security, is to study electronics emit electric field, magnetic field effects of noise on people. EMC is to ensure normal operation of the product for the purpose was to study electronics emit noise effects on other electronics, or from the effects of other electronic products.
RoHS is a mandatory standard developed by the EU legislation, it is the full name (on restrictions on the use of certain hazardous components in electrical and electronic equipment directive) (Restriction of Hazardous Substances).
On January 3, 2013 Directive 2002/95/EC will be abolished, the allies must be updated before January 2, 2013 directive 2011/65/EU to local law. 2011/65/EU main contents are summarized as follows: 1. control product range illustrated instructions and related definitions, to expand the control to all electrical and electronic equipment unless a special exemption:-8th products include 2002/95/EC exemption of medical equipment, 9th products surveillance equipment; -11th class product: not 1~10 type of products covering all other electrical and electronic equipment, including cables and other components. 2. restriction material while not adding new material, but with 4 kinds of selected toxic substances (HBCDD; DEHP; DBP and BBP) as a candidate for restricted substances. 3. the CE marking requirements to include electrical and electronic equipment ROHS compliance in CE-marking requirements. Producers to post a CE identification shall ensure that the products comply with ROHS and prepare declarations and technical documentation. 4. the transitional period provides for the inclusion of new ROHS 2.0 control manufacturers sufficient time to comply with the directive, ROHS 2.0 sets a controlled transition period for related products.
FCC attestation introduction
FCC (Federal Communications Commission, United States Federal Communications Commission) is the United States Government, an independent agency, directly responsible to Congress. FCC Engineering Department is responsible for the Commission's technical support and equipment recognition Affairs. in accordance with United States Federal Communication Commission regulations (CFR 47 part), entering the United States electronic products need to be certified electromagnetic compatibility (except for some special provisions in the relevant articles) called the FCC certification.
FCC certification is common in three ways: Certification, DoC, Verification. These three product certification program, there is a big difference, different products are available in the Select authentication method in the FCC rules. Its strict certification descending. These three kinds of certification, FCC Committee on laboratory related requirements.
FCC to develop regulations to reduce electromagnetic interference, the regulation and control of radio frequency range, protection of telecommunication networks, electrical products work properly. Electromagnetic interference divides into conducted interference and radiated interference. EMI through the power line communications, frequency 30MHz, and interference audio frequency band. If electrical products have a metal shield, the main influence for conducted interference. conducted interference is a measure of the size of many electrical devices (such as computer power supplies), an important criterion for quality. we may have such experience in their daily work, when the computer is powered on and near electrical appliances such as televisions, audio does not work properly, this is the effect of conduction interference. An example of radiated interference is, cell phone use, computer screens near apparent dithering noise signal sound can be heard in the radio.
