As a part of the circuit of household electrical appliances, electronic wires are ubiquitous in our daily life. As a standard industrialized product, electronic wires must have relevant qualification certifications. Then, what kind of qualified electronic wires need to be obtained? What about qualification certification?
First, the electronic wire must first have UL certification
UL certification is not only a certification of electronic wire products, but also a testing standard for commodities. The English name of UL is Underwriter Laboratories Inc. The Chinese translation is: Underwriters Laboratories of the United States. It is an independent, profitable, third-party non-profit organization that conducts tests for public safety. It selects scientific testing methods for each product. Parameter input testing to prevent harmful chemical substances from flowing into the market. For example, lead PVC insulation in electronic wires is a chemical substance harmful to the environment and everyone’s health. UL testing will specifically detect this substance.
The electronic wire testing standard established by UL certification is not only one of the important testing conditions for the import of goods in the United States, but also provides a complete testing standard for the electronic wire industry. Whether the electronic wire is safe and stable, the relevant UL certification It is one of the important references.
Second, the electronic wire must obtain the SGS test report.
SGS (Swiss General Notary Company, called SGS Standard Technical Service Co., Ltd. in China) is a third-party impartial organization engaged in inspection, testing, appraisal and certification. Whether the electronic wire is exported or sold domestically, the purchaser will request an SGS report, the purpose of which is to verify whether it complies with relevant regulations or ROHS environmental protection standards through a third-party impartial organization.
The core content of the RoHS directive is to restrict the use of toxic substances in electrical and electronic equipment, protect the environment, provide green consumption, and achieve the destruction and harmlessness of the two fields of production and consumption. Through testing the electronic wire, to see whether there are lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers in the electronic wire, which are harmful to the human body, refuse to let the toxic substances flow to the market, and whether the electronic wire can pass the SGS related The ROHS standard environmental protection test is also one of the important references for the quality of electronic wires.
The UL standard and SGS report will not only restrain and standardize the electronic wire industry, but also have an insignificant effect on the import and export of the electronic wire industry. In summary, a high-quality electronic wire must obtain UL certification and SGS report, so that such electronic wire products are more safe, stable and reliable.
