Chemical Fume Hood/ASHRAE 110 Testing
MSS offers comprehensive testing and certification of Chemical Fume Hoods including ASHRAE 110 testing. MSS Fume Hood testing and certification services are executed in accordance with MSS's Standard Operating Procedures (SOPs) which are updated to remain compliant with current federal and international industry standards and guidelines.
Chemical Fume Hoods are tested in accordance with AIHA/ANSI Z9.5, SEFA, ASHRAE 110 & OSHA.
Primary tests include:
- Inflow [face] velocity profiling
- Airflow smoke patterns testing
- Cross draft airflow testing
Additional tests where specified may include:
- Airflow alarm installation and calibration
- ASHRAE 110 testing to include:
- Inflow [face] velocity profiling
- Small and large volume smoke testing
- Cross draft airflow testing
- Tracer gas containment testing
- Variable Air Volume testing
As per ANSI/AIHA Z9.5, 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 ASHRAE 110 provides a means of quantifying containment performance.
MSS has extensive experience with this valuable testing tool and in assisting clients in identifying and correcting performance deviations.
MSS also provides consultation and guidance on the development of fume hood testing protocols to support airflow reduction and energy conservation efforts.
