GB/T 42827-2023 A.C.ventilating fans and regulators for household and similar purposes—Methods for measuring performance

Scope

This document specifies the performance and corresponding test methods for AC ventilation fans and their speed controllers used in single-phase AC circuits with a voltage not exceeding 250 V and an input power not exceeding 125 W (including corresponding speed controllers), driven by single-phase AC motors, and intended for forced ventilation and air exchange in household and similar applications. This document applies to ventilation fans, such as wall-mounted ventilation fans and ducted ventilation fans installed in windows and walls. Note: This document does not apply to: -- Safety of household and similar appliances - Part 2: Special requirements for fans (GB 4706.27); -- Performance test methods for comfort fans (IEC 60879); -- Performance test methods for cooking range hoods (IEC 61591); -- Special requirements for noise test methods for household and similar appliances - Particular requirements for fans (GB/T 4214.9); -- Electromagnetic compatibility requirements for household appliances, power tools, and similar devices - Part 1: Emission (GB 4343.1); -- Electromagnetic compatibility requirements for household appliances, power tools, and similar devices - Part 2: Immunity (GB/T 4343.2); -- Electromagnetic compatibility limits - Part 1: Harmonic current emission limits (equipment with a per-phase input current ≤16 A) (GB 17625.1); -- Electromagnetic compatibility limits for voltage changes, voltage fluctuations, and flickering generated by equipment with a rated current ≤16 A and unconditional access to public low-voltage power supply systems (GB/T 17625.2).
