New threshold exhaust flow rates for capture and containment of cooking effluent.

This paper presents results of applying the capture and containment test procedures in ASTM Fl 704-96, Standard Test Method for Performance of Commercial Kitchen Ventilation Systems, to determine the threshold capture and containment exhaust flow rates for a number of cooking appliances and two types of kitchen exhaust hoods. It presents new data showing threshold capture and containment values for several common cooking appliances and compares them to both the International Mechanical Code values and test values based on Underwriter Laboratories Standard 710, Standard for Exhaust Hoods for Commercial Cooking Equipment.
