What is the purpose of ASTM E283 testing?

The purpose of ASTM E283 testing is to assess air leakage through building components such as walls, windows, doors, and other assemblies. This standardized method measures the amount of air that passes through the material or assembly under a specified pressure difference, allowing professionals to quantify the air permeability of the building envelope. By understanding the air leakage rates, builders and designers can make informed decisions to improve the air barrier performance, contribute to energy efficiency, and enhance indoor environmental quality.

In this context, while evaluating the performance of air barrier materials and the overall air barrier system are important aspects of air barrier design, ASTM E283 specifically targets the quantification of air leakage, which is crucial for ensuring that the building envelope effectively restricts unwanted air flow. This distinction emphasizes the importance of the specific testing parameters outlined by ASTM E283.
