3、hamber.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
4、of range hoods under controlled laboratory conditions suitablefor 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 unitsin parentheses, the second value may be approximate. The first stated value is the requirement.1.

Intentional inlets and outlets include the ra
22、nge hood exhaust duct. The test chamber shall be pressurized to 50 Pa. The airflow required to maintain this pressure (Q50 (L/s) shall be measured and recorded. This flow shall be converted into Air Changesper Hour using Eq 1:Air Changes per Hour53.63Q50V (1)The test chamber shall have less than 2.5
