Many of you have already seen this I’m sure, but for those who haven’t and are interested, and as it came up in conversation recently, a link to Bob Livingston’s excellent article on motor testing. Scroll down through it and you get a good explanation of setup and how he tested RPM and Torque, and how torque was tested at lower voltages and then given an appropriate multiplying factor. This seemed to be an acceptable practice. If not entirely accurate, results with the same equipment and methodology should at least be relatively accurate. Setup’s are relatively easy to duplicate should you be interested in doing it yourself.

If anyone is further interested I could see if I could find the manufacturers graphs showing the same thing wrt torque.
