Foreword
This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents".
Drafting.
This document supersedes GB/T 10893.1-2012 "Compressed Air Dryers - Part 1.Specifications and Tests" and GB/T 10893.2-2006.
"Compressed Air Dryers - Part 2.Performance Parameters". This document is based on GB/T 10893.1-2012, and integrates GB/T 10893.2-
The content of.2006.Compared with GB/T 10893.1-2012, apart from structural adjustments and editorial changes, the main technical changes are as follows.
---The scope has been changed (see Chapter 1, Chapter 1 of the.2012 edition);
---Terms and definitions that were defined in the referenced documents have been removed (see Chapter 3, Chapter 3 of the.2012 edition);
---Added solutions suitable for the operating conditions of compression heat dryers (see Table 2);
---Added conditions suitable for the stability of compression heat dryers (see 7.2);
---The requirement for pressure drop has been increased (see 7.3).
This document is modified to adopt ISO 7183.2007 "Compressed air dryers - Specification and testing".
This document has undergone significant structural adjustments compared to ISO 7183.2007.A table comparing the structural numbering changes between the two documents is provided.
See Appendix A.

Compressed Air Dryer Specifications and Tests
1 Scope
This document specifies the symbols, standard test conditions, and prescribed operating conditions for different types of compressed air dryers, and describes the performance testing.
The method provides information on uncertainties and experimental reports.
This document applies to adsorption-type compressed air dryers and membrane-type dryers with operating pressures greater than 0.05 MPa and less than or equal to 1.6 MPa.
Requirements and tests for compressed air dryers, refrigerated compressed air dryers (including those dried by cooling), and combined compressed air dryers.
This document does not apply to absorption compressed air dryers, overcompression compressed air dryers, or built-in compressed air dryers.
Note 1.The types and principles of compressed air dryers discussed in this document are detailed in Appendix C.
Note 2.This document specifies the partial load test method for determining the performance of energy-saving devices.
