ASTM E119-18 pdf free.Standard Test Methods for Fire Tests of Building Construction and Materials.
ASTM E119 described in this fire-test-response standard are applicable to assemblies of masonry units and to composite assemblies of structural materials for buildings, including loadbearing 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.
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 or 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 fire-resistive properties of materials and assemblies 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.
Such a standard is found in the test 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.
5. Test Specimen
5. I The test specimen shall be representative of the con- struction that the test is intended to assess. as to materials workmanship, and details such as dimensions of parts, and shall be built under conditions representative of those applied in building construction and operation. The physical properties of the materials and ingredients used in the test specimen shall be determined and recorded.
5.2 The size and dimensions of the test specimen specified herein shall apply for classifying constructions of dimensions within the range employed in buildings. When the conditions of use limit the construction to smaller dimensions. the dimensions of the test specimen shall be reduced proportion ately for a test qualifying them for such restricted use.
6. Protection and Conditioning of Test Specimen
6. 1 Protect the test specimen during and after fabrication to ensure its quality and condition at the time of test. The test specimen shall not he tested until its required strength has been attained, and, until an air-dry condition has been achieved in accordance with the requirements given in 6.2 — 6.4. Protect the testing equipment and test specimen undergoing the fire- resistance test from any condition of wind or weather that is capable of affecting results. The ambient air temperature at the beginning of the test shall be within the range of 50 to 90°F (10 to 32°C). The velocity of air across the unexposcd surface of the test specimen, measured just before the test begins, shall not exceed 4.4 ft (1.3 m/s). as determined by an anemometer placed at right angles to the unexposed surface. When mechanical ventilation is employed during the lest, an air stream shall not be directed across the surface of the test specimen.
9. Report of Results
9.1 Results shall be reported in accordance with the performance in the tests prescribed in these test methods. They shall he expressed in Lime periods of resistance, to the nearest integral minute. Reports shall include observations of details of the behavior of the material or construction during the test and after the furnace fire is extinguished. including information on defonmition, spalling. cracking, burning of the test specimen or its component parts. continuance of flaming, and production of smoke.
9.2 Reports of tests in which restraint is provided for the test specimen shall describe the method used to provide the restraint.
9.2.1 Describe the physical details of the restraint system and provide information to define the longitudinal and rotational resistance of the test specimen by the restraint system.
9.2.2 Describe the restraint conditions with regard to the free movement of the test specimen prior to encountering resistance to expansion, contraction or rotation.ASTM E119-18 pdf free download.
