Why qualify this equipment?
Ces dispositifs ventilés permettent de maîtriser les flux d’air et de contenir les polluants particulaires et microbiologiques.
La qualification s’assure que chaque équipement répond aux normes réglementaires (ISO 14644, NF EN 14175, NF EN 12469, etc.) et offre les performances attendues en matière de sécurité et de protection.
Fume cupboard control
Control of Microbiological Safety Cabinets (MSC) and Laminar Flow Hoods (LFH)
fume cupboards
Measuring frontal air velocities
Check air velocity through the work opening to ensure effective containment of pollutants.
Containment tests
Use of gaseous tracers (SF6) to assess the capacity of the fume cupboard to contain pollutants.
Air flow visualization
Identification of areas of turbulence and possible aeraulic disturbances.
Comfort parameter measurement
Check temperature, humidity and sound pressure.
PSM and HFL
Microbiological Safety Cabinets (PSM) and Laminar Flow Hoods (HFL) are used to protect operators, products and the environment. This equipment controls unidirectional air flows to prevent contamination and guarantee a sterile workspace.
Particle counting
Measurement of suspended particle concentrations to check compliance with air cleanliness classes.
Measurement of particle removal kinetics and recovery time
These analyses enable us to check how quickly equipment can eliminate particles generated in the workspace, guaranteeing rapid return to clean conditions after a disturbance.
Airflow assessment
PSM Downflow, guard-vein and laminarity control for optimum protection against microbiological contamination.
HFL Checking the speed and regularity of unidirectional flow (horizontal or vertical) to protect products.
HEPA filter integrity tests
Filter leak detection to ensure effective filtration of fine particles and maintain a controlled environment.
Biocontamination control
Analysis of viable particles in the air and on surfaces to assess microbiological risks.
Air flow visualization
Use smoke to check the efficiency of downward or horizontal air flows, identify dead zones and ensure a sterile environment.
Comfort parameter measurement
Controls brightness, sound level, temperature and humidity.
