Steps
Identify ASTM F1704 (Standard Test Method for Capture and Containment Performance of Commercial Kitchen Exhaust Ventilation Systems) as the relevant performance test method, distinct from UL 710/710B listing tests
Use flow-visualization techniques described in F1704 to determine the capture-and-containment (C&C) threshold under both idle and specified cooking-load conditions for the actual hood/appliance/replacement-air configuration
Note that F1704 testing reflects a more realistic kitchen environment (multiple appliances, ambient drafts) than UL listing tests, which typically evaluate a single appliance in a draft-free space
Use the measured C&C threshold to validate or adjust the exhaust airflow rate specified for the hood, and re-test after any change to appliances, hood position, or makeup air configuration
Document results for the AHJ or engineer of record, especially where airflow was reduced from the original design for energy-savings (demand-control kitchen ventilation) purposes
Known gotchas
A UL 710/710B listing is a fire/safety-focused certification, not a capture-and-containment performance guarantee — passing UL listing does not mean the hood was verified against F1704
C&C performance is configuration-specific: changing appliance lineup, hood height, or replacement-air design can invalidate a prior F1704 result, so re-verification is needed after any material change
Field conditions (open doors, foot traffic, cross-drafts from HVAC) can defeat a hood that tested fine in a controlled F1704 setup — treat lab results as a starting point, not a field guarantee
