The testing equipment and sample undergoing the fire test shall be protected from any condition of wind or weather that might lead to abnormal 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 unexposed surface of the sample, measured just before the test begins, shall not exceed 4.4 feet per second, as determined by an anemometer placed at right angles to the unexposed surface. If mechanical ventilation is employed during the test, an air stream shall not be directed across the surface of the specimen.

  1. Prior to the fire test, constructions shall be conditioned with the objective of providing, within a reasonable time, a moisture condition within the specimen approximately representative of that likely to exist in similar constructions in buildings. For purposes of standardization, this condition is to be considered as that which would be established at equilibrium resulting from drying in an ambient atmosphere of 50 percent relative humidity at 73°F (23°C). However, with some constructions, it may be difficult or impossible to achieve such uniformity within a reasonable period of time. Accordingly, where this is the case, specimens may be tested when the dampest portion of the structure, the portion at 6-inch (152 mm) depth below the surface of massive constructions, has achieved a moisture content corresponding to drying to equilibrium with air in the range of 50 to 75 percent relative humidity at 73 + 5°F. In the event that specimens dried in a heated building fail to meet these requirements after a 12-month conditioning period, or in the event that the nature of the construction is such that it is evident that drying of the specimen interior will be prevented by hermetic sealing, these requirements may be waived, except as to attainment of a large portion of final strength, and in the specimen tested in the condition in which it then exists.

  FIRE-RESISTIVE STANDARDS

  2. Specimens shall be exposed to the controlled conditions outlined in Item 1 until the interior or dampest section of the assembly attains a relative humidity of 75 percent or less. If during the conditioning of the specimen it appears desirable or is necessary to use accelerated drying techniques, it is the responsibility of the laboratory conducting the test to avoid procedures which will significantly alter the structural or fire endurance characteristics of the specimen or both from those produced as the result of drying in accordance with procedures given in Item 1.
  3. Within 72 hours prior to the fire test, information on the actual moisture content and distribution within the specimen shall be obtained. This information shall be included in the test report.

  TESTS OF BEARING WALLS AND PARTITIONS

  Sec. 12-7-106.

  (a) Size of sample. The area exposed to fire shall be not less than 100 square feet (9.3 m [2] ) with neither dimension less than 9 feet (2743 mm). The test specimen shall not be restrained on its vertical edges. The fire testing furnace, its arrangement and control during fire tests shall conform to SFM 12-7-3, Section 12-7-301 (a), Vertical Large-scale Wall Furnace.
