- Scope
- This standard specifies the test method for the aerodynamic performance of air distributors. These include the type of test device, measuring instrument and its accuracy requirements, test methods and test data calculation methods used, etc. This standard is applicable to aerodynamic performance testing of various types of air supply vents and return air vents. This standard is applicable to aerodynamic performance tests under isothermal conditions (that is, the supply air temperature is equal to the room temperature or the temperature difference between the two is not greater than 2°C), and it also puts forward technical requirements for non-isothermal jet characteristic tests. Other products with similar uses can also refer to this standard.
