1、Designation:E233614An American National StandardStandard Test Methods forFire Resistive Grease Duct Enclosure Systems1This standard is issued under the fixed designation E2336;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year
2、of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe protection of grease ducts under fire exposure conditions is an item of importance in securingconstructions that ar
3、e safe,and that are not a menace to neighboring construction nor to the public.Recognition of this is registered in the codes of many authorities,municipal and other agencies.Manytypes of enclosure materials are used to protect grease ducts.Normally,these enclosure materials areeither applied to gre
4、ase ducts in the field or are fabricated as part of the grease duct when shipped fromthe factory.Evaluating enclosure materials used to protect a grease duct from fire is an aid forpredicting their fire performance and promotes uniformity in requirements of various authorities.Todo this it is necess
5、ary that the fire-endurance properties of enclosure materials be measured andspecified according to a common standard expressed in terms that are applicable alike to a wide varietyof materials,situations,and conditions of exposure.1.ScopeNOTE1The majority of this standard is based on the Model Build
