Air Infiltration, Water Resistance and Uniform Load Testing

Air filtration is determined by a high precision mass flow meter while the specimen is subjected to a constant air pressure differential. For water resistance tests, specimens are checked for water penetration under cyclic and static air pressure, which simulates differing storm conditions. QAI tests apparatus ensures that all test samples receive the necessary water application at the required test pressure conditions.

Test results determine if water penetration occurs inside the product or wall cavity. For the uniform load tests, the specimen’s structural integrity is evaluated while prescribed static high pressure differential is created across the specimen, simulating both positive and negative wind loads. QAI uses precise digital instrumentation to measure permanent set and deflection readings under ratios established by the standard.
