"CE" mark is a safety certification mark, is regarded as the manufacturer to open and enter the European market passport. CE stands for European harmonization (CONFORMITE EUROPEENNE). Where the "CE" marking of the product can be affixed to the EU members of the domestic sales, without having to meet the requirements of each member state, thus realizing the free flow of goods in the EU member states within the scope of the free flow of goods.
Most small and medium-sized enterprises in China are troubled by the fact that they can't finalize their export orders from Europe without CE marking certificates. Or when the goods arrive at the destination, because of the inability to CE marking certificate and detained by the customs, thus causing great losses. How to make your customers feel relieved to cooperate with you in the long run? With a marketable product and a product pass - CE marking certificate, your business will continue to flow.
EMC and LVD specific meaning
EMC and LVD is one of the directives in the CE marking. CE marking according to different products to make different directives certification.
EMC is the Electromagnetic Compatibility Directive of CE;
LVD is the Low Voltage Directive of CE,
The goal of LVD is to ensure the safety of low-voltage devices in use. LVD is defined as electrical equipment rated between 50 and 1,000 volts for alternating current (AC) and 75 and 1,500 volts for direct current (DC). Broadly speaking, LV equipment includes consumer products and equipment designed to operate in this voltage range. This includes household appliances, hand tools, lighting equipment, wires, cables and tubes, and wiring equipment. This directive contains all the safety rules for this equipment, including protection against hazards due to mechanical causes.
LVD Low Voltage Directive 73/23/EEC
-In 1973, the European **** the same body to develop & Adopted the Low Voltage Directive (Council Directive 73/23/EEC, Low Voltage Directive) referred to as the LVD; and in 1993 plus the Annex (Amendment) 93/68/EEC. Amendment) 93/68/EEC, and will be extended to January 1, 1995 implementation date. The directive provides that all electrical products are included in the rated range of control, must comply with the provisions of the directive, the directive in January 1, 1997 formally mandatory.
- Electrical products rated at 50V - 1000 Vac or 75 - 1500Vdc should comply with the LVD.
EMC Electromagnetic Compatibility Directive 89/336/EEC
On May 3, 1989, the European ****same body developed & adopted the Electromagnetic Compatibility Directive (Council Directive 89/336/EEC, Electromagnetic Compactity Directive) Abbreviated as EMC Directive; and revised in 1991, 1992, 1993. The revised version as a subsidiary directive 91/263/EEC, 92/31/EEC, 93/68/EEC. The directive stipulates that all electrical and electronic products entering the European market must meet the requirements of the relevant electromagnetic compatibility, according to the relevant EN standards for testing and retaining the report
