What is the ASTM 2128?

What types of building systems does the ASTM E2128 provide testing for?

The document provides a standard guide for evaluating water leakage in building walls, covering methods for determining causes, investigative techniques, safety considerations, and a systematic approach to evaluation. ​ It includes detailed guidance on planning, methods, equipment, and objectives for investigative testing to recreate leaks, trace internal paths, correlate results with observed damage, and verify hypotheses. ​

ASTM E2128 and the Evaluation Practices for Water Leakage

The document outlines investigation and evaluation practices for water leakage through various building components such as wood siding systems, concrete panels, windows, curtain walls, EIFS, stucco, and tile systems. ​

For the ASTM E2128, the Emphasis is placed on the importance of proper installation, maintenance, and inspection to prevent water leakage issues. ​
It discusses consequences, performance criteria, maintenance, and sources of water leakage in exterior wall assemblies, stressing the need for systematic analysis, cause-and-effect relationships, and detailed reporting in evaluations. ​
