Scope: This standard specifies two laboratory test methods for the capillary flow of refrigerants, the traditional method and the alternative method, to determine the capillary flow that regulates the refrigerant in a refrigeration system. Both methods use dry nitrogen and provide comparable results. If electronic equipment is used, alternative methods are more convenient. Through the test method of this standard, the flow characteristics of the refrigerant in the capillary can be obtained. However, the obtained results do not represent the actual flow characteristics of the refrigerant in the refrigeration cycle. This standard does not specify the tolerance requirements of the inner diameter of the capillary and the deviation requirements of the nitrogen flow rate, but it is recommended to give the acceptable deviation range of the test results.
