Significance and use
ASTM E2336 test methods are intended to evaluate the ability of the grease duct enclosure system to do the following:
- Resist the effects of a standardized fire exposure
- Retain its integrity, or
- Exhibit both properties dependent upon the type of test assembly involved during a predetermined test exposure.
ASTM E2336 test methods provide for the following measurements and evaluations where applicable:
Capability of the enclosure material to resist flaming (combustion) when exposed to 1382°F (750°C).
Load bearing ability of the tested support system and fastening system to carry the load of the grease duct enclosure system during a standardized fire-engulfment test.
Ability of a fire stop to meet the requirements of Test Method E 814 when used with a grease duct enclosure system.
Ability of the enclosure material to resist the passage of flames and hot gases during a standardized fire resistance test and a standardized internal fire test.
Transmission of heat through the grease duct and the enclosure material(s) during a standardized fire resistance test and a standardized internal fire test.
Ability of the grease duct enclosure system to resist the passage of water during a standardized hose stream test.
Comparative measurement of temperature aging of the enclosure material(s) when subjected to standardized cyclic thermal transmissions.
