Penalties for violation of the directive:
If the product is found to be non-compliant with the requirements of the directive in the EU market sampling, it will be returned to the market, and will be destroyed for a fee, etc. In fact, if the manufacturer of the whole machine can not provide evidence that the product is compliant with the directive, there will be no European importers and exporters will not buy this product.
The way to comply with the directive and pay attention to the problem:
1, although, the ROHS Directive put the responsibility on the machine manufacturer, did not put forward the requirements of components and materials manufacturers. However, for the whole machine manufacturing, the confirmation and traceability of raw materials and components is a key issue in controlling hazardous substances in products, therefore, the whole machine manufacturers will require raw materials and components manufacturers to provide test reports or certificates.
2. Unlike other EU directives, it is nearly impossible to verify whether a machine is compliant with the ROHS Directive through several tests. The most reasonable approach is to obtain test data from suppliers of raw materials and components, and then convert it into a declaration of conformity for the product. However, the machine manufacturer also needs to determine whether the test data of the material supplier is reliable, which can be judged by the following ways: investigating the reputation of the laboratory that issued the test data; sending random samples to be inspected by themselves.
3. In most cases, testing for all six hazardous substances is not necessary and the cost of testing is prohibitive. Therefore, it is necessary to consult professional organizations to determine which parts need to be tested for which types of hazardous substances. For example, testing of electrostatic coatings in integrated circuit blocks is publicly limited to lead because tin/lead is the most common material used in such coatings. Cadmium and hexavalent chromium are relatively difficult to detect here, and the presence of mercury, polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs) is even less likely.
4. It may be necessary to modify your quality system documentation to add the appropriate content.
5, product consistency is always a certain limit, the content of hazardous substances in the samples sent for testing, if very close to the limit, there is no guarantee that your products are in line with the requirements.
In February 2003, the European Parliament and the Council 2002/95/EC "Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Directive" was formally announced, ROHS is the English acronym for Restriction of Harzardous Sub-tances, the directive provides that: since July 1, 2006, all in the EU Since July 1, 2006, all large household appliances, small household appliances, IT and communications equipment, user equipment, lighting equipment, electrical and electronic tools, toys, leisure and sports equipment, medical equipment, monitoring and control equipment, vending machines and other ten categories of products sold on the market must restrict the use of the heavy metals lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+) and the organics polybrominated diphenyl ethers (PBDE) and polybrominated biphenyls (PBDE). ) and polybrominated biphenyls (PBB). The directive will give China's exports of electrical and electronic products to Europe has a significant impact on the domestic industry should pay great attention to the implementation of this environmental protection directive, if not in advance to take effective measures, export enterprises will suffer huge losses.
In order to help enterprises to deal with the EU ROHS Directive, to expand exports, Zhuhai Inspection and Quarantine Bureau of Technology Center to provide inspection and related consulting services to enterprises to guide you on how to choose the test samples and testing methods, how to control the content of hazardous substances in the product, and issue ROHS test reports, so that your products can enter the EU market smoothly.
Enterprises should send samples before the need to test a whole machine, and at the same time the parts of the detailed split to a single homogeneous body, metal 20-30 grams, non-metallic 30 grams, the liquid shall not be less than 100 ml (attached to the list of materials and specify the supplier), respectively, packaged and sent to my center, or entrusted to my center to carry out the splitting. After splitting, it is usually divided into metal parts and non-metal parts. Metal parts usually need to test only the content of four heavy metals, lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+), while non-metal parts need to be tested for polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs) in addition to the test of the above four heavy metals.
Testing time: After the test samples and fees are collected, it takes 5-7 working days for heavy metals in homogeneous substances and 5-10 working days for organic items; the whole machine usually takes about 10-20 working days, depending on the complexity of the actual product.
