Standard: ASTM E2128 - 12 – Standard Guide for Evaluating Water Leakage in Building Walls

Scope: This guide describes methods for determining and evaluating causes of water leakage of exterior walls.

Applicable Products: Building wall systems employing its exterior and interior finishes, fenestration, structural components, and components for maintaining the building interior environment. Sealants, masonry, windows and glass/metal curtain walls, exterior insulation and finish systems (EIFS), cement stucco and tile systems, wood and manufactured wood-based siding systems, fiber-cement and cement-bonded particle board siding systems, and precast concrete panels.

Test Procedure: Investigative testing is undergone in order to recreate leaks, trace internal paths of the leaks, correlate test results with observed damage and verify hypothesis using diagnostic test methods and procedures adapted from standard test methods such as E331, C1601, E547 to meet specific objectives. Diagnostic testing can also be adapted from in-service quality assurance testing procedures such as Test method E1105 or diagnostic test procedures such as Test Method C1715, AAMA 501.2, and AAMA 511.

End Result: Upon the completion of a successful test, the products meet the performance criteria for water penetration resistance or do not meet criteria and further remediation may be required to pass.
