From what I've read, test samples are generally checked at 4X or 5X,
then working parts proofed at 2X. I tested my overbuilt, overweight
scaffold section to 1000 Lbs vertically and 500 on all diagonals,
which the 3/4" EMT braces initially failed.
What is normal practice for testing a single piece without damaging it?
