Flame Spread Tester

I. Product Overview

A flame spread tester is a specialized device for evaluating the speed and range of flame propagation when materials are exposed to fire. By simulating specific combustion environments, it measures parameters such as flame spread rate and burning distance to determine the fire resistance of materials. Widely used in fields like building materials, textiles, and plastics, it complies with standards such as ASTM, ISO, and GB.

II. Key Features

  • Accurate simulation: Adjustable fire source intensity and ambient wind speed to replicate real combustion scenarios, with test repeatability error ≤5%.
  • Automatic monitoring: Equipped with infrared sensors and cameras to record the position of the flame front in real-time and automatically calculate the spread speed.
  • Safety protection: Fully enclosed test chamber with explosion-proof observation windows and automatic fire extinguishing systems to prevent flame leakage.

III. Common Specifications

  • Sample size: Length 300-1000mm, width 100-300mm, thickness ≤50mm (supports plates, coils, etc.).
  • Fire source parameters: Propane flame, temperature 600-1200℃, ignition time adjustable from 0-180s.
  • Device parameters: Test chamber size approximately 1.2×0.5×0.8m, power supply 220V/380V, power ≤1kW.

IV. Typical Applications

Flame spread testing of building insulation materials, fire performance evaluation of curtain fabrics, combustion propagation experiments of automotive interiors, and flame spread grade determination of cable bundles
