Testing Rectangular Box Profile

Hello everyone, i need help on a subject. I have to test a 30x50 2mm thick rectangular box profile in terms of bending. What procedures should i follow? My lecturer told me that i have to find ASTM standards for box profiles first, but i couldn't find that. Can you help me on the procedure?

The requirement is not very clear. Are all dimensions in mm? If it is a box one dimension is missing. Or is it a hollow rectangular section (30 x 50 mm) extruded beam? How is it bent/

Yes all dimensions are in mm, its length is 200mm. It is hollow, its thickness is 2 mm. Similar with the profiles in here https://www.raven.eu/offer/metallurg.../hollow-profiles-rectangular-box-section.aspx

We need bending along its long side
