(Test Method)Standard Test Methods for Fire Tests of Building Construction and Materials
Standard Test Methods for Fire Tests of Building Construction and Materials
SCOPE
1.1 The test methods described in this fire-test-response standard are applicable to assemblies of masonry units and to composite assemblies of structural materials for buildings, including bearing and other walls and partitions, columns, girders, beams, slabs, and composite slab and beam assemblies for floors and roofs. They are also applicable to other assemblies and structural units that constitute permanent integral parts of a finished building.
1.2 It is the intent that classifications shall register comparative performance to specific fire-test conditions during the period of exposure and shall not be construed as having determined suitability for use under other conditions or after fire exposure.
1.3 This standard is 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.
1.4 These test methods prescribe a standard fire exposure for comparing the test results of building construction assemblies. The results of these tests are one factor in assessing predicted fire performance of building construction and assemblies. Application of these test results to predict the performance of actual building construction requires the evaluation of test conditions.
1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.6 The text of this standard 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 standard.

INTRODUCTION
The performance of walls, columns, floors, and other building members under fire exposure
conditions is an item of major importance in securing constructions that are safe, and that are not a
menace to neighboring structures nor to the public. Recognition of this is registered in the codes of
many authorities, municipal and other. It is important to secure balance of the many units in a single
building, and of buildings of like character and use in a community; and also to promote uniformity
in requirements of various authorities throughout the country. To do this it is necessary that the

standard expressed in terms that are applicable alike to a wide variety of materials, situations, and
conditions of exposure.
Such a standard is found in the methods that follow. They prescribe a standard exposing fire of
controlled extent and severity. Performance is defined as the period of resistance to standard exposure
elapsing before the first critical point in behavior is observed. Results are reported in units in which
field exposures can be judged and expressed.
The methods may be cited as the “Standard Fire Tests,” and the performance or exposure shall be

expressed as “2-h,” “6-h,” “ ⁄2-h,” etc.
When a factor of safety exceeding that inherent in the test conditions is desired, a proportional
increase should be made in the specified time-classification period.
