This document specifies the symbols related to different types of compressed air dryers, the standard test conditions and specified operating conditions, describes the performance test methods, and provides information on uncertainties and test reports. This document applies to the requirements and testing of adsorption-type compressed air dryers, osmotic-membrane-type compressed air dryers, refrigeration-type compressed air dryers (including those dried by cooling), and combined compressed air dryers with operating pressures greater than 0.05 MPa and less than or equal to 1.6 MPa. This document does not apply to absorption-type compressed air dryers, over-compression-type compressed air dryers, and built-in compressed air dryers. Note 1: The types and principles of compressed air dryers covered in this document are described in Appendix C. Note 2: This document specifies the partial-load test methods used to determine the performance of energy-saving devices.
