ASTM E2319

ASTM E2319 is the standard test method for determining air flow through the face and sides of exterior windows, curtain walls, and doors under specified pressure differences across the specimen. It provides a defined way to evaluate how these building products respond to air pressure, helping support product comparison, performance assessment, and quality control. For projects where air leakage behavior matters, this standard offers a consistent technical basis for testing and documentation.

Overview of ASTM E2319

This ASTM standard focuses on measuring air flow through the face and sides of exterior fenestration and wall systems when pressure differences are applied across the specimen. Its role is to provide a repeatable test method that can be used to assess air movement in windows, curtain walls, and doors under controlled conditions. ASTM E2319 is commonly used when stakeholders need a reliable, standardized approach for evaluating air flow performance and comparing test results across products or specimens.

Common use cases of ASTM E2319

ASTM E2319 is typically used in laboratory or product evaluation settings for exterior windows, curtain walls, and doors. It may support testing during design verification, quality assurance, specification review, or procurement of building envelope products. The method is relevant when air flow through the face and sides of a specimen must be measured under defined pressure differences, making it useful for manufacturers, testing laboratories, and specifiers working with enclosure performance requirements.

Benefits of using ASTM E2319

Using ASTM E2319 helps create consistent test conditions and clearer performance comparisons for exterior windows, curtain walls, and doors. It supports compliance efforts, technical review, and product selection by giving teams a standardized way to measure air flow under pressure. That consistency can reduce ambiguity in testing, improve documentation for project requirements, and help identify whether a specimen meets expected air performance characteristics. For many users, ASTM E2319 is a practical tool for evaluation and risk reduction.
