Jiangsu Provincial Product Quality Supervision and Inspection Institute released a monitoring report on the quality risk of range hood products. Among the 50 batches of hood products sampled, 10 batches of products were unqualified, and 15 of them had unqualified electrical safety indicators. Electrical safety hazards.
According to the relevant personnel of the Quality Supervision Institute, the range hood products belong to CCC compulsory certification products, and must obtain CCC certificates in order to be sold in the circulation field. According to the website of China Quality Certification Center, 10 batches of commercially available range hood products in this spot check have not obtained CCC certificate according to law, and the production date of 1 batch of products is after the CCC certificate is revoked. Unlicensed production. These 11 batch range hoods are illegal products and are illegally sold. The remaining 39 batches obtained CCC certificates according to law and were produced during the period of validity of the CCC certificate.
Among the range hood products tested by this risk monitoring, 15 products have failed electrical safety indicators, mainly signs and instructions, internal wiring, structure, power connection and external cord, grounding measures, screws and connections, and creepage. 7 items such as distance do not meet the standard requirements, there are electrical safety hazards, which will bring about short-circuit of the circuit, and the metal casing is charged, which may cause electric shock and other safety hazards when the human body touches the casing.
Experts suggest that in the purchase of range hoods, ordinary consumers, in addition to paying attention to selecting well-known brands and obtaining CCC-certified products, can refer to several aspects, such as selecting the appropriate range of range hoods according to the installation space, and selecting according to the budget. The right price range. Among them, air performance is an important parameter of the performance of the range hood. For the performance of range hood products, the current effective national recommended standard is GB/T 17713-2011 "suction hood", which specifies three performance technical indicators for the air performance of the range hood, respectively, the air volume is 10m3/ Min, wind pressure 100Pa, full pressure efficiency 15%.
When purchasing a range hood, consumers can compare the air volume and wind pressure value of different brands of range hoods. When other indicators meet the requirements, the theoretical two values ​​are larger, the more the air performance of the range hood is. it is good. Author: Zhang Xu Chen Zhixuan
