What is a common method to confirm clamps remain sealed during a test?

• A. Perform a pull test on clamps.
• B. Replace clamps mid-test.
• C. Ignore minor tightness changes.
• D. Take a photo.

Answer: (A)

Evaluating whether clamps stay sealed during a test relies on directly checking the clamping force. A pull test applies a controlled tensile force to the clamps to verify they still grip securely and keep the joint closed under the test conditions. If a clamp slips or loosens, it reveals a potential leak path, allowing corrective action before any significant leakage occurs. Replacing clamps mid-test disrupts the procedure, ignoring small tightness changes is unsafe, and taking a photo only records appearance rather than the actual sealing integrity under load. The pull test directly assesses the ability of the clamps to retain the seal, making it the best method.
