Water Penetration Field Testing
Sovell Investigative Testing and Consulting (SITC) provides expert ASTM water penetration testing for residential, commercial, light commercial, and architectural projects across the United States.
- ASTM Quality Assurance (QA) Testing – for newly installed fenestration products
- ASTM Forensic (Investigative) Testing – for existing installations experiencing water intrusion
For examples of past projects, see our Projects Page.
SITC Testing Standards and Specifications
SITC utilizes a variety of ASTM standards and AAMA specifications depending on the type of testing required:
AAMA 502 – Quality Assurance Testing for Newly Installed Fenestration
- Edition: AAMA 502 Voluntary Specification for Field Testing of Newly Installed Fenestration Products
This standard applies to:
- Windows
- Operable doors
- Fenestration products
Important Requirements:
- For quality assurance testing only
- Must be performed prior to building occupancy permit issuance
- No later than six months after installation
Referenced Standards Include:
AAMA:
- AAMA/WDMA/CSA 101/I.S.2/A440
- AAMA 503
- AAMA 511
ASTM:
- ASTM E122
- ASTM E783
- ASTM E1105
- ASTM E2128
See our AAMA 502 Page for further information.
AAMA 503 – Storefront & Curtain Wall Field Testing
Edition: AAMA 503 – Voluntary Specification for Field Testing of Newly Installed Storefronts, Curtain Walls and Sloped Glazing Systems
- Scope: Quality assurance of newly installed storefronts, curtain walls, and sloped glazing systems
- Timing: Before occupancy permit and within six months of installation
- Exclusions: Windows, glass doors, and skylights (use AAMA 502)
Referenced Standards Include:
AAMA:
- AAMA 502
- AAMA 511
- AAMA AG-07
ASTM:
- ASTM E122
- ASTM E783
- ASTM E1105
- ASTM E2128
See our AAMA 503 Page for further information.
AAMA 501.2 – Diagnostic Field Water Checks
- Edition: AAMA 501.2 Quality Assurance and Diagnostic Water Leakage Field Check
Scope: Used for:
- Installed storefronts
- Curtain walls
- Sloped glazing systems
This method:
- Is diagnostic in nature
- Does NOT test rated wind-driven rain performance
- Does NOT apply to operable windows or doors
- Exclusions: Operable windows and doors
- Purpose: Not intended to simulate full wind-driven rain events; used for identifying leak paths in glazing details only
- References:
- AAMA: 502, 503, 511
See our AAMA 501.2 Page for further information.
AAMA 511 – Forensic Water Penetration Testing
- Edition: AAMA 511 Voluntary Guideline for Forensic Water Penetration Testing of Fenestration Products
- Scope: Forensic testing to recreate known leaks
Unlike quality assurance standards (AAMA 502 & 503), AAMA 511 is used to:
- Recreate known leak conditions
- Simulate weather events
- Identify leak paths
- Calculate differential air pressures experienced during wind-driven rain
This is an investigative tool used when leakage has already been reported.
- References:
- AAMA: 502, 503, AAMA/WDMA/CSA 101/I.S.2/A440
- ASTM: E1105, E2128
- Other: NOAA climatological data
See our AAMA 511 Page for further information.
ASTM Laboratory and Field Standards
SITC conducts both laboratory and field testing using these ASTM standards:
- ASTM E331 – Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls
Used for:
- Laboratory testing
- Interior mock-up testing
This test:
- Uses uniform static air pressure
- Defines apparatus, specimen size, and calibration requirements
Conducted in SITC’s laboratory facility.
ASTM E547 – Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls
Used for:
- Laboratory testing
- Interior mock-up testing
This method:
- Uses cyclic static air pressure
- Simulates fluctuating wind conditions
Conducted in SITC’s laboratory facility.
ASTM E1105 – Field Determination of Water Penetration
Used for:
- Quality assurance testing
- Forensic investigation
Advantages of Early Testing:
Testing at time of installation allows:
- Identification of fabrication errors
- Installation correction before wall completion
- Reduced repair costs
Forensic Applications:
Used after building completion to determine if leakage is due to:
- Installation failure
- Material failure
- System design issues
Procedures:
- Procedure A: Uniform static air pressure
- Procedure B: Cyclic static air pressure
SITC determines the appropriate procedure based on laboratory performance data.
- ASTM E2128 – Evaluating Water Leakage of Building Walls
Forensic/investigative testing to determine how, why, and to what extent a building leaks
SITC Approach to Water Penetration Testing
- Document Review: Evaluate design documents and project specifications
- Site Inspection: Assess as-built conditions and service history of the building
- Controlled Testing: Conduct reproducible field or laboratory tests to verify hypotheses
- Data Analysis: Establish cause-and-effect relationships between wall/fenestration characteristics and observed leakage
Our objective is to determine:
- Why the building leaks
- How the leakage occurs
- The extent of damage
- Reporting: Deliver clear, actionable reports with findings and recommendations
Why Choose SITC?
- Extensive experience across North America
- Both field and laboratory capabilities
- Quality assurance & forensic expertise
- Clear, professional reporting
- Standards-driven methodology
