[0005] From the above excerpts, we can know that the minimum width of the fabric sample specified by GB shall not be less than 51mm, but some narrow fabrics (such as rope and belt fabrics) are too narrow to meet the width standard. When the combustion performance of the fabric is tested, it is directly hung on the sample holder bracket, causing the sample to be heated and curled when the sample is ignited, and quickly leave the flame, failing to reach the burning time specified by GB.
The test result does not meet the national standard 12s ignition time

Abstract
The invention provides an auxiliary frame of a narrow fabric combustion tester. The auxiliary frame is matched with a specimen holder support for detection. The auxiliary frame comprises a vertically arranged metal body plate and a connecting plate connected to the lower end of the body plate, wherein a plurality of fixing needle plates are sequentially arranged on the connecting plate in the vertically direction, each fixing needle plate is provided with a plurality of fixing needles, and a fastening plate for being connected to the specimen holder support is arranged at the upper end of the body plate. According to the auxiliary frame, narrow flame-retardant fabric such as ropes, belts and the like is fixed on side surfaces of the fixing needle plate through the fixing needles, and positions between the narrow flame-retardant fabric and flames are adjusted through sliding the fastening plate on the specimen holder support for combustion tests. The narrow flame-retardant fabric is fixed on the fixing needles and prevented from leaving the flames quickly due to crimp with heat, so that national regulations are satisfied, and testing standards are met.
Description
technical field [0001] The invention relates to the field of experimental equipment, in particular to an auxiliary frame for a narrow fabric combustion tester. Background technique [0002] People have attached great importance to fire prevention and flame retardancy since ancient times, and the Song Dynasty also set up special fire protection agencies. With the development of society and the emphasis on life, the country has mandatory regulations on the flame retardancy of textile materials used in many fields such as construction and public transportation. [0003] "GB / T5455-1997 Textile Combustion Performance Test Vertical Method" stipulates the structure of the vertical combustion tester, the ignition method and time, and the size of the sample holder. The following is a partial excerpt from "GB / T5455-1997 Textile Combustion Performance Test Vertical Method": [0004] "Sample clamp: used to fix the sample to prevent curling and keep the sample in a vertical position. T...
