Window and Door Air tightness/Water tightness/Internal Wind Pressure Resistance Performance Test

Test Items

Window Set, Glass, Fire Door (Air tightness Performance)Performance, Internal Wind Pressure Resistance Performance (Displacement)

Test Subject

Window Set, Glass, Door (Fire Door, Revolving Door)

Test Standards

Air tightness Performance - KS F 2292, Water tightness Performance - KS F 2293, Internal Wind Pressure Resistance Performance - KS F 2296

Test Method

• ① Air tightness Performance Test: Pressurize and depressurize at 10 Pa, 30 Pa, 50 Pa, and 100 Pa to measure the airflow.
• ② Water tightness Performance Test: Apply uniform pressure, flood the front of the specimen with 4 liters/m² of water for 10 minutes, and visually confirm the extent of water overflow.
• ③ Internal Wind Pressure Resistance Performance Test: Apply positive and negative pressure to the specimen at 25%, 50%, 75%, and 100% of the target pressure, each for 10 seconds, and measure the displacement with the installed displacement gauge.
