What is the main focus of an assembly test?

The main focus of an assembly test is to verify the joints between the membrane and accessories. This step is crucial because the effectiveness of an air barrier system heavily relies on the integrity of these joints. If the joints are not properly sealed, they may allow air leakage, compromising the overall performance of the air barrier system. The assembly test specifically evaluates how well these components work together, ensuring that the connections can withstand environmental stresses and maintain the intended air barrier function.

While durability, material performance under pressure, and cost-effectiveness are important considerations in building and construction, they are not the primary objective of an assembly test. Durability may be assessed in other types of tests, while material performance is typically evaluated through different methodologies. Cost-effectiveness is a broader economic concern rather than a specific focus of assembly testing. Therefore, confirming the integrity of the joints is the critical aspect addressed in this type of testing.
