Modified ASTM E1105 — Modified E1105 / Gravity-Flow Water Test
A modified E1105 procedure using gravity-flow water application where a sealed test chamber and controlled air pressure aren’t practical on site.
What it measures
Water penetration under a calibrated spray without an applied air-pressure differential.
When to use it
Used where geometry or access prevents a standard pressurized E1105 chamber, but water performance still needs checking.
Frequently asked
- When is modified E1105 appropriate?
- When a sealed chamber can’t be built or pressurization isn’t feasible, but a documented water test is still required.
