In load testing, which statement about SWL is correct?

• A. Testing is done at SWL only
• B. Testing is done at SWL and above the SWL
• C. Testing is done below SWL
• D. SWL is not relevant to testing

Answer: (B)

SWL stands for Safe Working Load, the maximum load an item is designed to carry safely during normal use. In load testing, you want to verify not only that the equipment behaves safely at the rated capacity but also that there is a margin beyond it. Testing only at loads below the SWL won’t reveal how the system handles near-limit or slightly higher conditions, and testing only at or below can miss potential issues that appear as you approach the limit. By applying loads at the SWL and at higher levels, you confirm that the rating is accurate and that the structure, fastenings, and components maintain safety and performance under near-limit conditions. Of course, any testing above SWL must be conducted under strict safety protocols and according to standards.
