Cite ANSI/RESNET/ICC 380 blower-door and duct-leakage test procedures correctly

Steps

1. Confirm which edition applies to the job (2016, 2019, or 2022) — most jurisdictions require testing per the edition referenced by their adopted IECC/IRC cycle, not automatically the newest edition.
2. Use RESNET's own summary articles and technical explainers (resnet.us) for freely citable methodology basics: ducts are pressurized/depressurized to 25 Pa, both single- and multi-point blower-door tests are permitted, and both total-leakage and leakage-to-outside duct test methods (including Delta Q) are recognized.
3. For enforceable, word-for-word standard text (equipment calibration, tolerances, reporting formats), purchase the specific edition PDF from ANSI's webstore (webstore.ansi.org) or ICC — do not reproduce full standard text from third-party summaries.
4. Confirm any code trigger dates relevant to the job (e.g., homes permitted after a jurisdiction's 380-standard adoption date) against that jurisdiction's adopted code, not a generic national date.
