Steps
Recognize ASTM E514/E514M is a laboratory test method for wind-driven-rain water penetration through a built wall specimen, not a field/in-situ test -- for diagnosing an existing building, use a field method instead.
Use E514 primarily to evaluate a proposed new wall assembly, flashing detail, or mortar/masonry-unit combination in a lab mock-up before it is built.
Specify the test pressure differential, duration, and spray rate per the current E514/E514M edition, verified on astm.org's store rather than an outdated year.
Compare results against the project's own performance criteria set by the design team, since E514 itself does not define a pass/fail threshold.
For an existing leaking wall, pair any E514-informed design fix with field diagnostics (moisture mapping, RILEM tube testing, borescope inspection) to locate the actual entry point.
Known gotchas
Don't specify E514 as a field acceptance test for an already-built wall; it requires a fabricated lab specimen and is not equivalent to the field test method C1601.
E514 doesn't include a built-in numeric pass/fail criterion -- the design team must set acceptance criteria separately.
Confirm the current edition designation on astm.org before referencing test parameters, since the standard has been revised more than once.
