"CE" mark is a kind of safety certification mark, which is regarded as a passport for manufacturers to open and enter the European market. CE stands for obedient Europe. All products marked with "CE" can be sold in EU member states without meeting the requirements of all member states, thus realizing the free circulation of goods in EU member states.
What bothers most small and medium-sized enterprises in China is that the European export orders that are hard to get cannot be finalized because there is no CE certificate. Or after the goods arrive at the destination, they are detained by the customs because they cannot obtain the CE certificate, causing heavy losses. How to reassure your customers and cooperate with you for a long time? With marketable products and product pass-CE certificates, your business will continue.
The specific meaning of EMC and LVD
EMC and LVD are one of the directives in CE certification. CE certification makes different instructions according to different products.
EMC is the EMC instruction in CE;
LVD is a low voltage instruction in CE,
The goal of LVD is to ensure the safety of low-voltage equipment in use. Low-voltage equipment refers to AC electrical equipment with rated voltage between 50 and 1000 volts and DC electrical equipment with rated voltage between 75 and 1500 volts. Broadly speaking, low-voltage equipment includes consumer products and equipment designed to operate within this voltage range. Including household appliances, hand tools, lighting equipment, wires, cables and pipes and wiring equipment. This directive contains all the safety rules of the equipment, including the prevention of dangers caused by mechanical reasons.
LVD low voltage instruction 73/23/EEC
-1973, European isomorphism was formulated &; Low-voltage directive was adopted (annex 93/68/EEC was added to Council Directive 73/23/EEC for short, and the implementation date was extended to 1995 1. The directive stipulates that all electrical products must be controlled within the rated range and must comply with the terms of the directive. The directive was officially implemented on June 1 997 65438+1October1.
-Electrical products with rated voltage of 50V- 1000 vac or 75- 1500 VDC shall comply with the LVD low-voltage directive.
EMC electromagnetic compatibility directive 89/336/EEC
On May 3rd, 1989, Eurovision adopted the electromagnetic compatibility directive (Council Directive 89/336/EEC, abbreviated as EMC Directive); It has been modified several times in 199 1, 1992, 1993. The revised version is attached to Directives 9 1/263/EEC, 92/3 1/EEC and 93/68/EEC. The directive stipulates that all electronic and electrical products entering the European market must meet the requirements of relevant electromagnetic compatibility, be tested according to relevant EN standards and keep reports.
