These standards outline methods of fire tests for the fire-resistive properties of building constructions and materials and through-penetration fire stops of various materials and construction. These fire tests 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.

These requirements are intended to evaluate the length of time that these types of assemblies will contain a fire or retain their structural integrity, or both, dependent upon the type of assembly involved, during a predetermined test exposure. The test evaluates the assembly's resistance to heat, and in some instances to a hose stream, while carrying an applied load, if the assembly is load bearing. The results of these tests are one factor in assessing predicted fire performance of building construction and assemblies.

Full Scale Furnaces

Full Scale Horizontal Furnace

Standards Include: Horizontal Floor and Deck Assemblies Horizontal Thermal Barriers Through-Penetration Fire Stops for Floor/Ceiling WFCi's most recent addition is the Horizontal Furnace used for Full Scale testing of floor/ceiling assemblies in accordance with test standards (notably ASTM E-119). The furnace is 7 feet deep and with collar can be expanded to test columns. It will accommodated samples up to 14 feet wide by 18 feet long.The furnace utilizes unique burners which produce lazy, yellow diffusion flames like earlier furnaces which generated historical fire resistance data. It is able to do so even when run at positive pressure all the way to the floor if desired.

Full Scale Vertical Furnace

WFCi Can Satisfy Your Full Scale Testing Needs. Standards Include: Building Constructions Fire Door Assemblies Fire Window Assemblies The furnace used for fire resistance tests of building constructions and materials (notably ASTM E-119) and fire door and window assemblies is a large-scale, fire-burning apparatus fueled by natural gas. The furnace is mounted to the floor, with the back side close to the west wall, at the south end of the laboratory facility. Inside the laboratory to the north of the furnace is a large area for specimen construction and curing. Ambient temperature in the laboratory is controlled by natural gas radiant heaters at the ceiling level. A wall section can be mounted, in a vertical orientation, into a steel frame specimen holder. The specimen holder is then rolled up to the furnace and secured by four pneumatic rams to the furnace opening. Combustion air and natural gas are supplied to burners through a series of pipes and valves. Internal furnace pressure is controlled by a series of dampers in the exhaust outlets. Temperature measurements are recorded by calibrated data acquisition units which pass the readings to a computer for graphical display and storage. A large roll up door is in the wall opposite the furnace area and allows for the samples to be moved approximately 40' on tracks outdoors to the area designated for hose stream testing.

Equipment Details

The furnace can run under positive or negative pressures to comply with standard requirements. Special burners were designed to create historical lazy yellow luminous diffusion flames under positive pressure conditions so that the sample performance under the new positive pressure requirements is similar to historical performance under negative pressure. The furnace is capable of loading samples, per the standard. The furnace can follow the new standard hydrocarbon curve.

Research Scale Furnaces

Research Scale Horizontal Furnace

WFCi's Research Scale Horizontal Furnace. Standards Include: Horizontal Floor and Deck Assemblies Horizontal Thermal Barriers Through-Penetration Fire Stops for Floor/Ceiling The furnace used for horizontal research-scale fire resistance tests of building constructions and materials, such as horizontal floor and deck assemblies, thermal barriers (in accordance with UBC 26-2 and ASTM E-119) and floor and ceiling fire stops is a small-scale fire burning apparatus, fueled by natural gas. The sample is mounted on to the top of the furnace horizontally. The exposed surface is subjected to the time-temperature curve, while temperature measurements are taken from the unexposed surface, using a computerized data acquisition system. The furnace valves are controlled based upon the average of the interior furnace temperature, which is determined from the internal thermocouples. Additional thermocouples are added to the unexposed surface of the specimen to monitor its temperature.

Research Scale Vertical Furnace

Standards Include: Building Constructions Fire Door Assemblies Fire Window Assemblies The furnace used in the for vertical pilot-scale fire resistance tests of building constructions and materials and fire door and window assemblies is a small-scale fire burning apparatus, fueled by natural gas. The test assembly is mounted onto a steel frame specimen holder and installed onto the furnace vertically. The exposed surface is subjected to the time-temperature curve, with temperature measurements taken on the unexposed surface of the door and frame using thermocouples connected to a computerized data acquisition system. The furnace valves are controlled based upon the average of the interior furnace temperature that is determined from five internal thermocouples.

Equipment Details

There are windows in the sides of the furnace to allow viewing of the specimen's exposed surface and the taking of photographs during testing. Upon completion or early termination of a test, the main gas supply valve is closed and the specimen is removed from the furnace, allowing for hose stream testing, if applicable, and allowing for post-testing observations. Ambient temperature in the laboratory is controlled by natural gas radiant heaters at the ceiling level.

Door and Window Fire Resistance Testing

Standards Include:
ASTM E 152
ASTM E 2010
ASTM E 2074
NFPA 252
NFPA 257
UBC 7-2
UBC 7-4
UL 10B
UL 10C
UL 9

These fire-test-response standards are applicable to door and window assemblies, including glass block and other light-transmitting assemblies, for use in walls to retard the passage of fire. These standards determine the ability of door and window assemblies to function as a fire-resistive barrier during a standard fire endurance test. They are intended to evaluate the ability of the assembly to remain in an opening during a predetermined test exposure, which, when required, is then followed by the application of a hose stream.
