Chemical Fume Hood Testing Services
Airtest provides comprehensive chemical fume hood testing services for compliance to ANSI/AIHA Z9.5, SEFA 1 including:
Face velocity profiling
Cross draft testing
Small and large volume airflow visualization testing
Face velocity testing of chemical fume hoods alone is not considered a sufficient demonstration of hood performance, as laboratory environmental factors may compromise hood performance. Quantitative containment tracer gas testing of chemical hoods under as-installed and as-used conditions as outlined in ANSI/ASHRAE 110 provides a means of quantifying containment performance. Airtest has extensive experience with this valuable testing tool and in assisting clients in identifying and correcting performance deviations.
