19、ers. These grease lters are intended for installation and use in accordance with the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, NFPA No. 96 and the International Mechanical Code (IMC). 1.1 effective August 6, 2012 1.2 Grease extraction devices integral to

20、the exhaust hoods that use them and other lter devices designed to be used in only the specic manufacturers hoods are not covered by this standard but are tested under the Standard for Exhaust Hoods for Commercial Cooking Equipment, UL 710, or the Standard for Recirculating Systems, UL 710B, or the

21、Outline for Ultraviolet Radiation Systems for Use in the Ventilation Control of Commercial Cooking Operations, Subject 710C. 1.2 effective August 6, 2012 1.3 The test methods described in this standard pertain to lters used in exhaust hoods for commercial cooking operations. The primary function of

22、these devices and the capability of devices tested in this standard are to prevent ames from penetrating into the exhaust system beyond the hood collar. The terms grease and oil are used interchangeably in this standard 1.3 effective August 6, 2012 1.4 Filters are investigated to determine their abi

23、lities to: a) Limit the projection of ames downstream when subjected to ames on the upstream face, after having been loaded with grease in a manner representative of cooking that produces a grease-rich exhaust, b) Drain any collected grease in such a manner that it does not fall back onto the cookin

24、g surface. 1.4 effective August 6, 2012 1.5 The standard does not measure capture efficiency or physical robustness of the grease lter device or other factors that do not directly affect user or re safety. Note: Capture efficiency of a kitchen hood lter can be measured using ASTM F2519 “Standard Tes
