ASTM E547 Laboratory Water Penetration Testing
ASTM E547 – Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Cyclic Static Air Pressure Difference – is a laboratory test method used to evaluate the water resistance of exterior fenestration products under cyclic pressure conditions.
At Sovell Investigative Testing and Consulting (SITC), ASTM E547 testing is conducted in our laboratory to assess product performance in accordance with ASTM International requirements.
What ASTM E547 Testing Evaluates
ASTM E547 determines the resistance of exterior windows, doors, skylights, and curtain wall assemblies to water penetration when subjected to:
- Cyclic static air pressure differences
- Continuous water spray applied to the exterior face and exposed edges
This cyclic loading simulates fluctuating wind pressures and wind-driven rain conditions that exterior products may experience in service.
How ASTM E547 Differs from ASTM E331
While ASTM E547 and ASTM E331 both evaluate water penetration resistance, they differ in how pressure is applied and which products are tested.
- ASTM E331 uses a uniform static air pressure difference
- ASTM E547 uses a cyclic static air pressure difference
Windows and doors are rated and certified in the laboratory based on specific performance classes or grades. The applicable test method is determined by the performance classification of the product.
In certain cases, both ASTM E331 and ASTM E547 are performed on a product as part of the Hallmark certification process.
Performance Classes and Testing Responsibility
It is the responsibility of the testing agency to work directly with the window or door manufacturer to understand the intended performance class or grade the product is designed to achieve.
Clear communication is critical to ensuring the correct test method is selected and that testing aligns with the manufacturer’s certification and performance goals.
Experience and Client Communication
One of SITC’s greatest strengths is communication with our clients. We work closely with manufacturers to ensure testing objectives are clearly defined before testing begins, allowing our clients’ goals to drive the testing process.
Sovell Investigative Testing and Consulting has conducted ASTM E547 laboratory testing for:
- General Electric
- HomeFlash
- Systems Control
