Fabric products fireproofing agent after finishing fireproofing effect is commonly used to determine the method is in accordance with the different placement of fabric specimens can be divided into vertical method, horizontal method, 45 degrees tilt method.

1、Vertical method

This test method provides that the specimen is placed vertically (specimen length direction and horizontal line vertical), the combustion source in the specimen below the ignition, measuring the specimen of small ignition time, flame spread speed, carbonization area, carbonization length and other indicators. Suitable for fireproof woven fabrics, knitted fabrics, PU coated products, laminated products and other fire performance determination. Refer to the standard (GB/T5455- 1997 fabric products - burning performance test - vertical method.

2、Horizontal method

Horizontal method, also known as the tablet method, this method is used for pavement fabric, the specimen will be placed horizontally. The main determination of fabric products horizontal direction in the specified conditions of the burning speed, that is, the material or combination of heat and flame responsiveness, with reference to the standard GB 11049-1989.

After wetting the specimen on the bottom of the test chamber, pressed on the four sides and the specimen aligned metal cabinet, placed flat in the center of the specimen a piece of hexamethylenetetetramine, ignite the tablet and start timing, when the ignited flame or any spread of flame burning until extinguished, or let the flaming or flameless burning spread to any edge of the metal frame pressure plate hole, the test is terminated, stop timing. Use a steel ruler to measure the large distance from the center of the specimen to the edge of the damaged area and calculate the flame spread time.
