Data cable CE marking EN55035 standard processing guide

As an important accessory for connecting electronic devices, the quality and safety of data cables are directly related to the user's experience and the safe operation of the devices. In order to ensure the compliance of data cables in the European market, manufacturers need to apply for CE marking for their products and pay special attention to the EN55035 standard, which is a European standard on the immunity requirements for electromagnetic compatibility of multimedia equipment and applies to a wide range of electronic devices, including data cables. The following will detail the process of data cable CE marking EN55035 standard.

First, understand the EN55035 standard

EN55035 standard specifies the multimedia equipment in the electromagnetic environment should have the immunity ability to deal with interference from other equipment or electromagnetic sources. The standard applies to a wide range of multimedia equipment, including but not limited to IT equipment, audio equipment, video equipment and the connecting cables between them, such as data cables. Data cable as an important medium for transmitting signals, its electromagnetic compatibility directly affects the performance and stability of the entire system.

Second, prepare the information required for certification

Before the CE certification of data cables to the EN55035 standard, the manufacturer needs to prepare the following information:

Company information: including company name, address, trademark, business license and so on.

Product information: the name of the data cable, model number and so on.

Third, the choice of certification body

manufacturers need to choose a certification body to meet the EU requirements for CE certification. The certification body should have the appropriate qualifications and testing capabilities, in accordance with EN55035 standards for testing and evaluation of data cables.

Fourth, submit the application and send samples for testing

The manufacturer submits the application for CE certification to the certification body and provides the prepared information as mentioned above at the same time. The certification body will review the application information, and require the manufacturer to provide samples of the data cable to be tested.

After receiving the sample, the certification body will test the data cable according to EN55035 standard. Test items may include:

Immunity test: to assess the immunity capability of the data cable in an electromagnetic environment, including repeated bandwidth impulse noise interference and individual bandwidth impulse noise interference tests.

Electromagnetic compatibility test: Evaluate the performance of the data line in the electromagnetic environment to ensure that it will not interfere with or be interfered by other equipment.

V. Prepare Test Report and Review

After the test is completed, the certification body will prepare a detailed test report to document the test process and results. Manufacturers need to carefully review the test report to ensure its accuracy.

The certification body will audit the test report to confirm that the data cable meets the requirements of the EN55035 standard. If the test report meets the standard, the certification body will issue a CE certificate.

To summarize, the process of CE marking of data cables to EN55035 standard involves a number of steps, including understanding the standard, preparing the information, selecting the certification body, submitting the application and sending the samples for testing, preparing the test report and auditing it, attaching the CE marking and maintaining the compliance, and so on. Manufacturers need to strictly comply with the relevant requirements to ensure that the quality and safety of data cables meet the standards of the EU market. By applying for CE marking, manufacturers can enhance the competitiveness of their products and win the trust and recognition of consumers.
