ROHS certification

  1.2.1 Introduction

        RoHS is the abbreviation of "the Restion of the use of certain hazardous substances in electrical and electronic equipment" (the Restion of the use of certain hazardous suNTEKances in electrical and electronic equipment). At present, it mainly focuses on the lead Pb in electrical and electronic products,

     Cadmium Cd, mercury Hg, hexavalent chromium Cr6+, polybrominated biphenyls PBBs, polybrominated diphenyl ethers PBDEs six harmful substances are restricted. More harmful substances will also be restricted in the future.

         The directive was proposed by the European Parliament and the Council, and the EU member states will enforce it on July 1, 2006. Electronic and electrical products containing harmful heavy metals and using polybrominated biphenyls and polybrominated diphenyl ethers as flame retardants are prohibited from entering the EU market.

   1.2.2 Certification mark

   1.2.3 Technical Information

        The maximum allowable content (threshold value) of the RoHS directive (2002/95/EC) for hazardous substances: Cd threshold is 100ppmm; Pb, Hg, Cr6+, PBBs, PBDEs threshold is 1000ppm; its test methods also need to be coordinated by various countries.

1.2.4 Product Scope

The scope of the Rohs directive covers the electronic and electrical products listed in the catalog below AC1000V and DC1500:

1. Large household appliances: refrigerators, washing machines, microwave ovens, air conditioners, etc.

2. Small household appliances: vacuum cleaners, electric irons, hair dryers, ovens, clocks, etc.

3. IT and communication equipment: computers, fax machines, telephones, mobile phones, etc.

4. Civil equipment: radios, televisions, video recorders, musical instruments, etc.

5. Lighting appliances: fluorescent lamps other than household lighting, lighting control devices

6. Power tools: electric drills, lathes, welding, sprayers, etc. (except for large industrial tools that need to be installed)

7. Toys/entertainment, sports equipment: electric cars, video game consoles

8. Medical equipment: radiotherapy apparatus, electrocardiogram tester, analytical instrument, etc.

9. Monitoring/control equipment: smoke detectors, incubators, factory monitoring and control machines, etc.

10. Vending machines

Among them, the RoHS Directive does not apply to Articles 8 and 9 for the time being.

All of the above are within the scope of NTEK business

1.2.5 Factory inspection

  No factory inspection is required,

   But generally speaking, ROHS will require a one-year validity period, mainly because some well-known international companies will require your report to be valid for one year, or half a year when purchasing your products, or a limited Korean company requires three It is valid every month. Some companies even require testing to be effective only for each batch of goods. Why do they do this? It is to continuously monitor the stability of the supplier's products, which depends entirely on the buyer's requirements. But once you find that your product has changed, such as a change in the production process, a change in the production process, or a change in your supplier, you are required to re-test. These are the practices of the company to protect itself. At present, general enterprises require a validity period of one year. In fact, the ROHS test report itself is only based on the analysis of the product. As long as your product material, production process and process remain unchanged, the test report can be effective for a long time.

1.2.6 Certification notice

1. The first batch of exemption list includes related substances in 9 products:

1 The mercury of small fluorescent lamps, the mercury content of each lamp does not exceed 5 mg;

2 Mercury in general-purpose straight fluorescent lamps (there are corresponding restrictions on the content of mercury salts);

3 Mercury in straight fluorescent lamps for special purposes;

4 Mercury in other lamps;

5 Lead in cathode ray tubes, electronic components and fluorescent tubes;

6 The weight percentage of lead in the alloy does not exceed 0.35% in the steel base, 0.4% in the aluminum base, and 4% in the copper base.

7 Lead in high melting point solders (exemption period until 2010); Lead in solders used for network switches, signal transmission and communication network management equipment; Lead in electronic ceramic components (such as piezoelectric components).

8. Cadmium coatings other than those prohibited by the Lubricant Directive (91/338/EEC and 76/769/EEC);

9 Hexavalent chromium in the carbon steel cooling system for corrosion protection of absorption refrigerators.

2. The second batch of exemption list may include 22 products, pending release.

Types and limits of controlled hazardous substances

See the core content of the ROHS Directive for specific types and limits.

Description:

1. The above limit comes from a meeting of the European Union in December 2003. It has been widely adopted internationally. However, as the EU's final regulations have not yet been completed, the limit is still subject to change.

2. For the types of controlled hazardous substances, the European Union has been conducting relevant research, and it is likely to continue to increase the types of controlled substances in the future.

1.2.7 Certification information and process

Certification information

ROHS testing product data preparation:

1. Only heavy metal detection: about 5-10g for solids and 5-10mL for liquids;

2. Only detect brominated flame retardants: about 10-20g for solids and 10-20mL for liquids;

3. Carry out the detection of organic pollutants sent by heavy metals: provide about 20-30g samples;

4. Carry out other organic pollutants detection: provide about 30g samples;

5. Only test the samples of the coating (coating) part, and the approximate weight of the material part of the coating (coating) should be indicated; if the weight of the coating (coating) part does not meet the requirements of the sample quantity, the coating should be provided ( Coating) raw materials
