Class 1 leakage is described as what?

Class 1 leakage is described as what?

• A. Seepage that forms drops but does not drip
• B. No seepage
• C. Seepage not great enough to form drops
• D. Seepage that drips during inspection

Answer: (C)

Leakage classifications look at how moisture appears at joints during inspection. Class 1 means you see seepage, but it’s very mild—there isn’t enough flow to form drops. You might notice a damp spot or a thin film, but no discrete droplets. This indicates only minor leakage that should be monitored and may be addressed with routine maintenance before it progresses. In contrast, seepage that forms drops or drips during inspection signals higher leakage and requires more immediate action, while no seepage means everything is completely dry.
