‘Test Method
Water pressure has been exercised on the pressurized side (A) in the order of pressure level, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, and 0.5Mpa. Water pressure has been applied for 15 minutes at each pressure level and occurrence of water leakage has been checked at the observed side (B).
