Steps
Confirm ASTM E283's current title/scope (rate of air leakage through exterior windows, curtain walls and doors under specified pressure differences) on astm.org or the ASTM store before citing it.
Confirm ASTM E330's current scope (structural performance of exterior windows, doors, skylights and curtain walls under uniform static air pressure difference).
Confirm ASTM E331's current scope (water penetration of exterior windows, skylights, doors and curtain walls under uniform static air pressure difference).
Match each method to the specific performance criterion being verified in the spec (air leakage rate vs structural deflection/permanent set vs water penetration) — these are typically run together, not as substitutes for one another.
Verify the specimen size, pressure differential, and duration required by the project spec against each standard's default test parameters, since specs often modify default test pressures.
Known gotchas
E283, E330 and E331 test three different performance attributes and are normally specified together in a mock-up program, not chosen as alternatives to each other.
Always confirm the current active edition on the ASTM store before citing a year — editions are periodically reapproved or revised.
