How to get CE certification? The following is a series of steps to obtain CE certification. Considering the difference of procts and their dangerous characteristics, several corresponding steps should be paid attention to. First, find out if there are any instructions applicable to your proct. If there is more than one such directive, your proct must comply with one of them. Determine to what extent your proct design and proction must meet the main requirements of the required instructions. Choose a unified assessment process based on the options provided in the instruction. Usually you have to fill in a & quot; Unified evaluation process & quot; Table, which asks you to provide proct characteristics in the form of a series of questions in order to classify its hazard level; At the same time, it includes many options to require manufacturers to confirm their procts and affix CE certification. The unified assessment process table requires that procts with low risk should be provided with a unified statement of self-test and attached with CE certification; The procts with high risk can apply for testing, supervision or other certification from the announcement agency. Choose applicable proct standards and testing methods for procts. If the proct needs to be tested separately, an independent laboratory shall be selected for testing. Set up an authorized representative for your procts in EU countries. Some directives require the manufacturer to appoint a representative in Europe to provide technical documents in time when the customer needs them. These instructions require manufacturers to prepare technical documents. In this way, customers can learn from the documents that the target proct has passed the test and meets the required standards. Prepare a unified declaration, including a package of instructions and standards your procts comply with, proct certification, manufacturer name, address and signature. CE certification itself does not provide details of the proct to the authority. The information in the uniform declaration must be detailed. According to this table, the manufacturer or its authorized representative in the EU can be found. Pasting of CE certification mark. The paste of CE certification mark must be in accordance with the regulations. The regulations indicate the size and pasting position of CE certification mark; Attach the logo to the proct, packaging, materials or documents shipped with the proct; There are restrictions on when and who can paste the CE mark. Who will carry out CE certification? According to the general proct safety directive (92 / 95 / EC), each member state of the EU can use laws, regulations and administrative regulations to ensure the safety and reliability of procts put on the market. As for specific implementation, each country has its own set of methods. Many countries set up special personnel to carry out on-site inspection of the instructions, and accept and handle consumer complaints. In other countries, the return of goods to the place of origin and economic punishment are combined. However, most countries adopt the mechanism of monitoring and training procers and distributors rather than resorting to legal action. Generally, such training is provided by the customer to the manufacturer. EU law stipulates that importers are responsible for the safety of their imported procts, including the machines provided by importers to employees for proction.
9. In September, many ministries and commissions took strict regulatory measures against virtual currencies such as bitcoin, and the prices of corresponding virtual currencies also fluctuated greatly
while the major bitcoin trading platforms have closed their trading services, some domestic "mining machines" for bitcoin mining have also lost their use. Mining machines and graphics cards used to dig bitcoin are being sold
it is understood that before, some low-quality "mining" people bought graphics cards and used them for mining. After a few days of mining, they returned the used graphics cards to the shopping platform by using the return and exchange policy of the shopping platform. Shopping platform will generally check the graphics card, find no damage after repackaging to the next consumer. This is undoubtedly damaging the interests of other consumers
"even the graphics card manufacturers themselves can't use an absolutely accurate method to judge whether the graphics card has been mined after only 1-3 months. There are some buyers who buy second-hand graphics cards. If they use them to play games, they will not be able to bring the machine with them when they buy "mine cards." The aforementioned instry insiders told reporters
"with the recent wave of changes, the market has changed too much. I don't think the ultimate value of graphics card is mining. After all, bitcoin mining also depends on the scale effect, which is the future trend. A few people's graphics card mining will eventually be eliminated. I hope the market will return to rationality. " Another bitcoin miner thinks so
the country's explicit restrictions will certainly only devalue more and more
