ASTM E2226
Standard Practice for Application of Hose Stream
What it measures
The companion to a fire-resistance test. Immediately after the furnace exposure, a duplicate specimen is hit with a fire hose stream at a specified pressure and duration to prove the assembly does not disintegrate under fire-fighting conditions.
Why it matters for a panel envelope
An assembly can survive the heat and still fail when water hits it. Codes require the hose stream for many rated assemblies, so a rating quoted without it is incomplete.
