What is the EU standard for standard products?

RoHS is a mandatory standard formulated by EU legislation, and its full name is Restriction of Hazardous Substances in Electronic and Electrical Equipment. This standard was formally implemented on July 1 2006. It is mainly used to standardize the materials and process standards of electronic and electrical products, making them more conducive to human health and environmental protection. The purpose of this standard is to eliminate six substances of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers in electronic and electrical products, emphasizing that the lead content should not exceed 0. 1%. The main sources of lead involved are as follows.

[Edit this paragraph] Basic contents of EU RoHS and WEEE directives

On February 3, 2003, 13, the European Parliament and the European Commission issued WEEE and RoHS directives in their official gazette on restricting the use of certain harmful substances in electrical and electronic equipment.

RoHS directive and WEEE directive stipulate ten categories 102 products, and the first seven products are the main export electrical products in China. Including large household appliances, small household appliances, information and communication equipment, consumer goods, lighting equipment, electrical and electronic tools, toys, leisure and sports equipment, medical instruments (except implanted or infected products), monitoring and control instruments and vending machines.

[Edit this paragraph ]RoHS directive restricts the use of the following six harmful substances

1 mercury (mercury) Examples of using this substance: thermostats, sensors, switches and relays, and light bulbs.

Examples of lead using this substance: solder, glass, PVC stabilizer.

Examples of cadmium using this substance: switches, springs, connectors, housings and printed circuit boards, contacts and batteries.

Example of chromium (hexavalent) using this substance: metal with corrosive coating.

Five examples of PBBs using this substance: flame retardant, PCB, connector, plastic shell.

6 PBDE examples of using this substance: flame retardant, PCB, connector, plastic shell.

[Edit this paragraph] Test principle:

According to the EU WEEE &；; RoHS directive requires AOV to classify products according to materials and detect harmful substances with different materials. Generally speaking:

Metal materials need to detect four harmful metal elements such as cadmium, cadmium, lead, mercury, mercury and Cr6+ hexavalent chromium.

In addition to these four harmful heavy metal elements, we should also test the brominated flame retardant (PBDE) of plastic materials.

At the same time, packaging materials with different materials also need to be tested for heavy metals (94/62/EEC).

The following are the upper limit concentrations of six harmful substances specified in RoHS:

Cadmium: less than 100ppm

ROHOS lead: less than 1000ppm.

Less than 2500ppm in steel alloy

Less than 4000ppm in aluminum alloy

Less than 40000ppm in copper alloy

Mercury: less than 1000ppm

Hexavalent chromium: less than 1000ppm

[Edit this paragraph] Why should RoHS be introduced?

In 2000, when cadmium was found in the cables of some game machines sold in the Dutch market, people first noticed that electrical and electronic equipment contained heavy metals harmful to human health. In fact, solder and ink printed on packaging boxes widely used in the production of electrical and electronic products all contain harmful heavy metals such as lead.

[Edit this paragraph: When will RoHS be implemented?

The EU will implement RoHS on July 1 2006. At that time, electrical and electronic products using or containing heavy metals and flame retardants (such as PBDE and PBBs) will not be allowed to enter the EU market.

[Edit this paragraph] What products does RoHS specifically involve?

RoHS is aimed at all electrical and electronic products that may contain the above six harmful substances in the production process and raw materials, mainly including: white goods, such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, etc. Black household appliances, such as audio-visual products, DVDs, CDs, TV receivers, IT products, digital products, communication products, etc. Power tools, electric electronic toys and medical electrical equipment

[Edit this paragraph] Current RoHS progress

Some big companies have noticed RoHS and started to take countermeasures. For example, Sony's digital camera, the box has indicated that this product uses lead-free welding; Print with lead-free ink.

In 2004, the Ministry of Information Industry also promulgated the Administrative Measures for Pollution Prevention and Control of Electronic Information Products, which is similar to RoHS, and established the Working Group on Pollution Prevention and Control Standards of Electronic Information Products in 10 to study and establish a standard system for pollution prevention and control of electronic information products in line with China's national conditions. To carry out research and revision of the relevant standards for pollution prevention and control of electronic information products, especially to speed up the formulation of basic standards such as materials, processes, terms, test methods and test means urgently needed by the industry.

[Edit this paragraph] The impact of ]RoHS on China's electronics industry

According to the latest data of China Electrical Apparatus Industry Association, in the first quarter of 2004, China's mechanical and electrical products exports accounted for 55% of China's exports. The EU has become the main export market of mechanical and electrical products in China. Due to the backward environmental protection concept and technical level of China manufacturers, RoHS directive makes China's nearly $27 billion mechanical and electrical products face the environmental protection barrier of EU.

China government has been paying close attention to and studying the countermeasures, and the State Council has specially instructed the Ministry of Information Industry to study and respond to the EU environmental protection directive. The Management Measures for Pollution Prevention and Control of Electronic Information Products formulated by the Ministry of Information Industry according to the Cleaner Production Promotion Law and the Law on the Prevention and Control of Environmental Pollution by Solid Wastes have been completed and come into force on June 5438+1 October1day, 2005.

The Administrative Measures for Pollution Prevention and Control of Electronic Information Products stipulates that electronic information products listed in the Key Catalogue of Pollution Prevention and Control of Electronic Information Products shall not contain toxic and harmful substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated diphenyl ethers and polybrominated diphenyl ethers from July 1 2006. Before July 1 day, 2006, the government of China asked the manufacturers of electronic information products to take measures to reduce the production of toxic and harmful substances and actively look for substitutes.

At the same time, an organization named "Working Group on Pollution Prevention and Control Standards for Electronic Information Products" has also begun to prepare for its establishment. Its main task is to study and formulate the pollution prevention and control standards of electronic information products in line with China's national conditions, and to carry out the research and formulation of relevant standards for pollution prevention and control of electronic information products, especially to speed up the formulation of basic standards such as urgently needed materials, processes, test methods and experimental methods.
