Diagnostic repair narratives live on storefront water-intrusion repair. This page is design-phase method selection for field water testing.
Start from specification intent
Read the project specification section that names the field test. Note whether the intent is quality-assurance sampling during construction, forensic diagnosis after a leak, or contractual acceptance testing. The method name, sampling rate, and pass/fail criteria belong in the specification or a written testing plan, not in memory.
High-level method distinctions
INFORMATIONAL COMPARISON ONLY. Confirm every parameter against the current official standard and the project specification. Not a substitute for purchasing the standards.
| Topic | ASTM E1105 (field water penetration) | AAMA 501.2 (QA hose method) |
|---|---|---|
| Typical role on commercial jobs | Standardized field water-penetration test method referenced for fenestration performance checks | Quality-assurance hose procedure commonly used to check installed fenestration workmanship |
| Where numeric parameters live | In the current ASTM E1105 text and any project modifications | In the current AAMA 501.2 text and any project modifications |
| Specification practice | Cite edition/year and any project deviations in writing | Cite edition/year, sampling, and acceptance language in writing |
| What this page will not do | Publish invented pressures, durations, or nozzle setups | Publish invented spray rates or pass/fail shortcuts |
Selection checklist
- Does the specification name ASTM E1105, AAMA 501.2, both, or another method?
- Is the purpose QA during install, acceptance, or forensic diagnosis?
- Who hires the testing agency, and who remediates failures?
- Which openings are in the sample set, and who protects adjacent finishes?
- Are product-approval / shop conditions consistent with the assembly being tested?
What to prepare in the field
Access, water source, power, interior protection, and a written sequence so the test does not become an uncontrolled wetting of unfinished spaces. Coordinate Division 07 transitions before blaming the glazing alone for a fail.
How to ask for a test-ready package
Send the specification section naming the test method, elevations, and whether ACG is furnish-and-install or supply-only. ACG: (772) 486-7711. FL CGC #1531993.
Frequently Asked Questions
What is the difference between ASTM E1105 and AAMA 501.2?
They are different published methods used for different field water-check intents. Read the project specification and the current official standards for apparatus and acceptance criteria. This page does not invent pressures or spray rates.
Can I use AAMA 501.2 if the spec names ASTM E1105?
Not as a silent substitute. Obtain written direction before changing the specified method.
Who usually hires the testing agency?
Follow the project specification and general conditions. Do not assume the glazing sub always pays for third-party testing.
Where should numeric test parameters come from?
Only from the current official standard text and any written project modifications, never from memory or this article.
