ویژگی‌های مرتبط با محصول:
  • Tests door operation under forces up to 1.5 times the required opening force.
  • Ensures microwave radiation emission does not exceed 5 mW/cm² at 5 cm from the enclosure.
  • Performs 10 to 50 opening and closing cycles based on appliance type (household or commercial).
  • Evaluates door integrity after impact tests on inner and outer viewing screen barriers.
  • Considers different installation arrangements (counter-top, built-in) for force application.
  • Uses spring scales or equivalents to apply precise forces during testing.
  • Tests side-hinged and bottom-hinged doors with specific force requirements.
  • Includes dowel tests to assess door closure under adverse conditions.
سوالات متداول:
  • What is the purpose of the UL923 Microwave Cooking Appliances - Door Assembly Tests?
    These tests ensure that microwave oven doors can withstand operational forces without compromising radiation containment, maintaining safety standards.
  • How many times are the door opening and closing tests performed?
    Household appliances undergo 10 cycles, while commercial appliances undergo 50 cycles to ensure durability under frequent use.
  • What happens if a door fails a test during the sequence?
    If a failure occurs, the test is repeated on a new sample. If the new sample passes, testing continues until all required tests are completed or another failure occurs.
