What is the WIP test result for storage?

• A. less than 2 inches
• B. less than 3 inches
• C. less than 4 inches
• D. equal to 3 inches

Answer: (B)

In this WIP test for storage, you’re looking at how much water intrusion the storage area can tolerate during the test. The measurement is a water depth, recorded in inches, inside the storage space after applying the test conditions. The goal is to keep that intrusion below a defined limit so the contents stay dry and protected. A reading that is less than 3 inches shows the storage resists water intrusion effectively under the test, meaning the seals, doors, and drainage meet the required tolerance. If the depth were equal to or greater than 3 inches, that would indicate excessive intrusion and a failure of the protective measures. The 3-inch threshold is set based on design and safety considerations to ensure stored items remain protected under expected conditions.
