This standard specifies the energy efficiency level, energy efficiency limit values, energy-saving evaluation values, test methods, and inspection rules for range hoods. This standard applies to outdoor range hoods installed on household cooking stoves, stoves, or similar appliances with a rated voltage not exceeding 250V. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document. GB/T 2828.1 Sampling Procedures for Inspection by Attributes - Part 1: Sampling Plans for Batch Inspection Retrieved by Acceptance Quality Limit (AQL) - GB/T 2829 Sampling Procedures and Tables for Periodic Inspection by Attributes (Applicable to Inspection of Process Stability) - GB/T 17713-2011 Range Hood 3 Terms and Definitions - GB/T 17713-2011 and the following terms and definitions apply to this document 3.1 Minimum allowable values of energy efficiency for range hood The minimum allowable values of energy efficiency for range hood under specified testing conditions. 3.2 Evaluating values of energy conservation for range hood The minimum allowable energy efficiency value of an energy-saving range hood under specified testing conditions. 3.3 Standby mode: The range hood is connected to the power supply and only provides restart, information or status display (including clock) functions, without providing any main function status. Note: The restart function refers to a function that switches the appliance to the main function mode provided through remote control, internal sensors, or timing clocks 3.4 Off mode is a state where the range hood is connected to the power supply but does not provide any standby mode or main functions. Note: When only providing shutdown status indication (such as LED), it is also considered to be in shutdown mode
