SAE J1677 - 5.2 (Reverse Flattening Test) and how it should be carried out

Hopefully someone here has had some experience with this standard, and can provide some guidance.
We manufacture single-wall and double wall tubing in a variety of sizes. Some of the testing we conduct is listed under the above-mentioned standard. There is currently come controversy about 5.2 (Reverse Flattening Test) and how it should be carried out.
My interpretation of the standard is that the tube is sectioned, leaving the weld in the middle of the section, and then the part is placed either concave or convex, and the part is flattened to the original material thickness.
Another interpretation is that the part is bent 'backwards' 180 degrees, which greatly increases the stress on the weld and surrounding areas.

I am almost completely confident that I am correct, but this is a fairly new process to me, so I want to be sure before making any changes to our test instructions.
:thanks:
