Fire Resistance Test Apparatus Of Rigid Thermoplastic Materials

What is the Fire Resistance Test Apparatus Of Rigid Thermoplastic Materials?

The Fire Resistance Test Apparatus for Rigid Thermoplastic Materials is a specialized testing device designed to evaluate the fire performance of rigid thermoplastics under controlled combustion conditions. This apparatus subjects material samples to a defined flame exposure while measuring key parameters such as ignition time, flame spread rate, and heat release rate. Utilizing advanced sensors and data acquisition systems, it provides precise assessments of thermal degradation and smoke emission, ensuring compliance with fire safety standards for applications in construction, automotive, and industrial sectors.

Compliance：UIC 564-2 "Regulations relating to fire protection and firefighting measures in passenger carrying railway vehicles or assimilated vehicles used on international services", Appendix 11 "Fire resistance of rigid thermoplastic materials" and Appendix 12 "Fire resistance of floor coverings".

Main parameters:

1. Test box/fume hood: a combustion box with a volume of 2.0M³, without ventilation;

2. Burner:

2.1 Structure: the gas s upply part of the burner is Ф10mm±0.2mm in inner diameter; the head is a strip-shaped nozzle with a length of 48mm±1.0mm, 3.0mm±0.2mm;

2.2 Flame size: the inner flame (blue) is 6mm±1.0mm, the outer flame is 35mm±1.0mm,

2.3 Installation: the burner is at an angle of 45°, and the surface of the outer flame touching the sample is 50mm±1.0mm away from the bottom of the sample;

3. Sample bracket: It is a U-shaped stainless steel bracket, with a shape of 318mm in length, 175mm in width, and a stainless steel side width of 20mm;318mm in length, 175mm in width, and a stainless steel side width of 20mm;

4. Fixer: Fix the sample holder in a vertical position, so that the flame can directly act on the surface of the sample;

5. Gas source:
