What should be done during the hydrostatic test to ensure that no portion of the piping is subject to freezing?

Explanation:
Preventing freezing during hydrostatic testing is essential because water inside the pipes can freeze and expand, causing damage and making the test unreliable. The correct approach is to take precautions so no portion of the piping experiences freezing—keep the area warm, insulate exposed runs, circulate heated water, or perform the test in conditions where freezing won’t occur. The other ideas—adding ice, testing only in warm weather as a rule, or ignoring freezing risk—would promote freezing or ignore the risk, which is unsafe and not in line with good practice.
