Proposed ASTM Standard to Test Ventilation When Cooking

WEST CONSHOHOCKEN, PA — A proposed new ASTM International standard will help determine how well a kitchen range hood exhausts pollutants from a stovetop. These pollutants include moisture, odors, and chemicals and particles that are health hazards. 

The proposed standard (WK55797, Test Method for Measuring Capture Efficiency of Domestic Range Hoods) is being developed by ASTM International’s committee on performance of buildings (E06).

ASTM member Iain Walker notes that the standard will determine a “capture efficiency rating” that tells what fraction of the cooking emissions are vented directly outside. A higher rating indicates better performance.

“We anticipate that the standard will be used by the kitchen ventilation industry,” said Walker, a scientist at the Lawrence Berkeley National Laboratory. “Products could be labeled with their capture efficiency rating, allowing contractors and consumers to ask for higher performing range hoods.”
