Vacuum cleaners can be divided into vertical, horizontal, and portable types according to their structure. The working principle of a vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, generating negative air pressure inside the sealed shell and absorbing dust. Let's introduce the testing standards and items of vacuum cleaners below Vacuum cleaner testing standards: 1. Meet the requirements of "3C certification", CNCA-01C-016:2010 "Implementation Rules for Compulsory Certification of Electrical and Electronic Products - Household and Similar Purpose Equipment" 2. GB 4706.1-2005 "Safety of Household and Similar Purpose Electrical Appliances - Part 1: General Requirements" 3. GB 4706.7-2004 "Safety of Household and Similar Purpose Electrical Appliances - Part 2: Special Requirements for Vacuum Cleaners and Suction Cleaners" 4. GB/T20291-2006 "Performance Testing Methods for Household Vacuum Cleaners" 5. GB/T 26125-2011 "Testing Methods for Six Restricted Substances in Electronic and Electrical Products"
