Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 1236-2000 "Industrial Fan with a standardized duct performance test."
This standard compared with GB/T 1236-2000, in addition to editorial changes outside the main technical changes are as follows.
--- Remove the original standard in the 14.9;
--- Removed the original standard in Chapter 22;
--- Removed the original standard in Chapter 24;
--- Removed the original standard in chapter 29;
--- In Chapter 21 "Determination of flow", delete the original standard "ISO Venturi nozzle, 90 ° arc inlet nozzle", and the tapered
Import and arc import merger; these deletions and changes at the same time in the standard Chapter 22, Chapter 23, Chapter 24, Chapter 25
Respectively, made the corresponding changes;
--- Added Chapter 27 "Rectifier";
--- Removed the original standard appendix C;
--- Added Appendix C "wind chamber leakage test method";
--- Added Appendix E "fan device input power consumption";
--- Added Appendix F "preferred method of performance testing";
--- In Chapter 30, Chapter 31, Chapter 32, Chapter 33, on the test method of different test equipment introduced in the calculation method, delete
The first case of the "simplified method" in the corresponding chapter of the original standard is that the base Mach number is less than 0.15 and the pressure ratio is greater than 1.02.
This standard uses the translation method identical with ISO 5801.2007 "Industrial Fan with standard duct performance test."
The documents of our country that are consistent with the corresponding international documents that are normative references in this standard are as follows.

For ease of use, this standard made the following editorial changes.
--- "This International Standard" changed to "this standard";
--- Use the decimal point "." Instead of as a decimal point comma ",";
--- Remove the original standard in the foreword and introduction;
--- The original standard Appendix C, in this standard as "Appendix NA" as an informative annex;
--- In the cited documents, note the date of the adoption of the Chinese standards corresponding to international standards.
