GB/T 12665-2008 specifies the humidity cabinet test requirements for motors under general environment conditions. The standard specifies the humidity cabinet test equipment, such as the technical parameters of the test chamber that can precisely control the temperature and humidity. Detailed description of the preparation of the motor test piece, put it under the heat and humidity conditions of the simulated general environment, specify the temperature and Humidity value, cycle cycle, etc. By observing the electrical performance and Mechanical Property changes of the motor during the test, evaluate its adaptability to the heat and humidity environment. This standard provides a unified specification for motor mass testing, helping to ensure stable operation of motors in common heat and humidity environments, prolong motor service life, and ensure the safe operation of power equipment.
