1. SCOPE

1.1 This Standard covers fire endurance tests applicable to walls, partitions, floors,
roofs, ceilings, columns, beams, and girders, as well as to some components of these building
sub-assemblies.
Note: It should be recognized that the performance displayed by a component in one assembly would
not necessarily be the same when such component is tested in a dissimilar assembly.

1.2 It is the intent that the fire endurance period established by this test method
indicates performance only during the fire exposure period and shall not be construed as having
determined suitability for use after fire exposure.

1.3 Separate fire endurance test methods are prescribed for various building
constructions and materials, as follows:
Walls and Partitions, Loadbearing (Section 6)
Walls and Partitions, Non-loadbearing (Section 7)
Columns (Section 8)
Columns, Steel, Tests of Protection for (Section 9)
Floor and Roof Assemblies (Section 10)
Beams or Joists, Loaded, Restrained (Section 11)
Beams or Joists, Loaded, Alternative Classification Procedure (Section 12)
Beams and Girders, Steel, Alternative Tests of Protection for (Section 13)
Framing and Facings, Combustible, Tests of Protection for (Section 14)
Ceiling Membranes (Section 15)

1.4 The fire exposure and hose stream tests are not intended to be representative
all fire conditions. It is likely that conditions will vary with changes in the amount, nature and
distribution of fire, loading, ventilation, size and configuration of assembly installed. This fire
endurance test Standard provides a relative measure of fire performance of comparable
assemblies under specified fire exposure conditions.
