scope:

This standard is intended to measure the capture and containment performance of ventilation extraction systems during simulated cooking conditions of an extraction device installed over standardized cooking appliance thermal plume challenges under specified appliance configurations and positioning, in kitchens and other companies processing foodstuffs intended for commercial use. This test method describes flow visualization techniques that are used to determine the threshold of capture and containment capture and containment for non cooking and specified heavy cooking conditions. The threshold of capture and containment can be used to estimate minimum flow rates for hood/appliance systems. The test procedure determines static pressure differential after the exhaust collar of the hood. It does not apply to household kitchens.
