1.1 This test method measures the capture efficiency of wall-mounted domestic range hoods under controlled conditions in a test chamber.

1.2 This test method applies to range hoods that exhaust air to outside and does not apply to recirculating range hoods.

1.3 This test method only applies to range hood air flows up to 200 L/s and widths up to 0.91 m (36 in.).

1.4 This test method is intended to quantify the capture efficiency of range hoods under controlled laboratory conditions suitable for rating.

1.5 The values stated in SI units are to be regarded as standard. If a value for measurement is followed by a value in other units in parentheses, the second value may be approximate. The first stated value is the requirement.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 Cooking can be one of the most polluting activities commonly and regularly occurring in residential environments. Capturing airborne cooking contaminants before they can mix with the indoor air is a critical indoor air quality control method.

5.2 Range hoods are used in homes to remove cooking-generated contaminants above cooking surfaces before they mix with air in the rest of the house. This test method is used to measure the capture efficiency under specific conditions that permit comparisons and ratings of range hoods.

5.3 Range hoods may be manufactured and intended to operate at different flow rates or using different inserts such as filters. This test method may be used to determine capture efficiency over the range of rated air flows and operating configurations of a range hood. The rated air flows shall be listed and shall be tested in accordance with HVI Test Procedure 916, IEC 61591, ASHRAE 51/AMCA 210, or equivalent. The maximum air flow allowed for this test method is 200 L/s.
