Standard Test Methods for Fire Resistive Grease Duct Enclosure Systems
SIGNIFICANCE AND USE
5.1 These test methods are intended to evaluate the ability of the grease duct enclosure system to do the following:
5.1.1 Resist the effects of a standardized fire exposure,
5.1.2 Retain its integrity, or
5.1.3 Exhibit both properties dependent upon the type of test assembly involved during a predetermined test exposure.
5.2 These test methods provide for the following measurements and evaluations where applicable:
5.2.1 Capability of the enclosure material to resist flaming (combustion) when exposed to 1382°F (750°C).
5.2.2 Loadbearing 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.
5.2.3 Ability of a fire stop to meet the requirements of Test Method E814 when used with a grease duct enclosure system.
5.2.4 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.
5.2.5 Transmission of heat through the grease duct and the enclosure material(s) during a standardized fire resistance test and a standardized internal fire test.
5.2.6 Ability of the grease duct enclosure system to resist the passage of water during a standardized hose stream test.
5.2.7 Comparative measurement of temperature aging of the enclosure material(s) when subjected to standardized cyclic thermal transmissions.
5.3 These test methods do not provide the following:
5.3.1 Full information as to performance of the enclosure material or the grease duct enclosure system constructed with components, densities, or dimensions other than those tested.
5.3.2 Evaluation of the degree by which the enclosure material or grease duct enclosure system contributes to the fire hazard by generation of smoke, toxic gases, or other products of combustion.
5.3.3 Measurement of the degree of control or limitation of the passage of smoke or products of combustion ...
SCOPE
Note 1: The majority of this standard is based on the Model Building Code Evaluation Service2 Acceptance Criteria titled ACCEPTANCE CRITERIA FOR GREASE DUCT ENCLOSURE ASSEMBLIES, AC101, which was created in 1994. Numerous design listings and labeled materials exist based on the provisions of this standard.
1.1 These test methods evaluate the enclosure materials and the grease duct enclosure systems using the following test methods: noncombustibility, fire resistance, durability, internal fire, and fire-engulfment with a through-penetration fire stop.
1.2 These test methods prescribe a standardized fire exposure for comparing the test results of the enclosure materials and grease duct enclosure systems. The results of these tests are one factor in assessing predicted fire performance of grease duct enclosure systems. Using these test results to predict the performance of actual grease duct enclosure systems requires the evaluation of test conditions.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 The text of these test methods references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the fire test response standard.
1.5 These test methods are used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.
1.6 These test methods do not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of these test methods to establish appr...

INTRODUCTION
The protection of grease ducts under fire exposure conditions is an item of importance in securing
constructions that are 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. Many
types of enclosure materials are used to protect grease ducts. Normally, these enclosure materials are
eitherappliedtogreaseductsinthefieldorarefabricatedaspartofthegreaseductwhenshippedfrom
the factory. Evaluating enclosure materials used to protect a grease duct from fire is an aid for
predicting their fire performance and promotes uniformity in requirements of various authorities. To
do this it is necessary that the fire-endurance properties of enclosure materials be measured and

INTRODUCTION
The protection of grease ducts under fire exposure conditions is an item of importance in securing
constructions that are 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. Many
types of enclosure materials are used to protect grease ducts. Normally, these enclosure materials are
either applied to grease ducts in the field or are fabricated as part of the grease duct when shipped from
the factory. Evaluating enclosure materials used to protect a grease duct from fire is an aid for
predicting their fire performance and promotes uniformity in requirements of various authorities. To
do this it is necessary that the fire-endurance properties of enclosure materials be measured and
specified according to a common standard expressed in terms that are applicable alike to a wide variety
of materials, situations, and conditions of exposure.
