Scope
With many corporations and suppliers conducting development and validation tests at different climatic wind tunnel sites, there is an increasing need for a recommended best practice that defines a process by which climatic wind tunnels can be correlated. This document addresses the test methods and metrics used to correlate results from different facilities, independent of location, for heating ventilation and air conditioning (HVAC) and powertrain cooling (PTC) development. This document should be used as a guideline to make sure key aspects of tunnel testing are covered when comparing various climatic wind tunnel facilities.
The depth of the correlation program is ultimately influenced by program objectives; therefore, a correlation program, for the intent and purposes of this document, can range from just a few tests to a full analysis that involves multiple vehicle tests identifying limitations and statistical boundaries. Using recommendations in this document will eliminate most of the items that effect facility mismatch in a correlation program.
Rationale
The document was updated to include specific requirements for electrified vehicles (BEVs, PHEVs, HEVs). Additionally, it was updated to incorporate latest best practices as well as updated formatting for improved clarity.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
